Deep Space 9 Superior

[Starbase]

Physiology
Breen physiology is among the most unique for humanoid lifeforms, which may be due, in part, to their homeworld's climate. The Breen have no blood or other liquid circulatory system. The Breen brain is structured into four lobes; this protects them from the probing of some empathic species, such as the Betazoids, who are unable to detect the thoughts or emotions of the Breen. (DS9: "In Purgatory's Shadow"; TNG: "The Loss")

The Breen body is able to take a considerable beating before being taken down. When Worf attacked a Breen with a blow that could normally fell a Nausicaan, the Breen was unfazed. It then successfully zapped him with its neural truncheon. (DS9: "Til Death Do Us Part")

Although it is often stated throughout the franchise that the Breen homeworld is a "frozen wasteland", Weyoun claimed in "The Changing Face of Evil" (DS9) that the Breen planet actually had a temperate climate, leaving one to wonder if the suits they wear are in fact to keep them cool.

Society and Culture
The Breen are known to use slave labor; and at least some of these slaves are captured in raids on other species. (DS9: "Indiscretion") They have been known to feed their prisoners a diet of algae paste. (DS9: "Til Death Do Us Part")

The Breen commonly produce offspring at a very early age. The Breen entertain their offspring with nursery rhymes. Breen nursery rhymes can be made up of a heterophonic, five-line verse with an alternating tetrameter and pentameter structure. These are nonsensical phrases strung together because they rhyme (at least to the Breen). Some Breen music, which can accompany these nursery rhymes, is written on a Lyxian scale. (DS9: "For the Uniform"; VOY: "Elogium")

It is unknown if this means a young average age for known humanoid species, or if the Breen have children at an age that would be considered young among Breen.

The Breen are very prudent when dealing with prisoners. They typically send in three guards at a time when they wish to remove a prisoner from their cell if there are multiple prisoners sharing the cell. (DS9: "Til Death Do Us Part") When Worf attempted to escape from captivity, the Breen used a type of neural truncheon to paralyze him. Even after he fell to the ground, partially paralyzed, two Breen guards continued to use the truncheons on him to ensure he would not get back up, before removing Ezri from the cell. (DS9: "Til Death Do Us Part") In another incident, Worf takes a single step towards Weyoun while showing signs of anger, and is again shocked by a neural truncheon to prevent him from doing anything. (DS9: "Strange Bedfellows")

From this we can extrapolate that the Breen have little tolerance for prisoners.
To extract information from captives, the Breen use cortical implants, despite the severe pain and damage it causes to the recipient. (DS9: "Til Death Do Us Part")

Science and Technology
Given that most known humanoid species live on class M planets with an average temperature far above the supposed temperature of Breen, the Breen are largely thought to have had to develop refrigeration suits in order to co-exist with others. However, if the Breen homeworld is temperate as suggested by Weyoun, then their reason for wearing environmental suits, if they were environmental suits at all, was much more mysterious. (DS9: "The Changing Face of Evil")

It should be noted that while Weyoun suggested the planet to have a more temperate climate, this may be a misguided opinion, as most other Alpha Quadrant species have suggested the Breen planet to be frozen over. It may also however be a testiment to the Breen's counter-intelligence.
The Breen were known for their knowledge of sophisticated cold-storage units, summed up in Captain Sisko's statement, "If anyone knows how to keep things cold, it's the Breen".

The Breen have also developed organic technology to the point where they routinely use biological spacecraft. Some of these ships are fitted with cloaking devices and the Breen are known to use type-3 disruptors like the Romulans and Klingons, as well as energy dampening weapons. The Breen made use of memory probing technology in the form of cortical implants and neural truncheons for subduing prisoners. (TNG: "Hero Worship"; DS9: "Indiscretion", "Til Death Do Us Part"; VOY: "Scorpion"; Star Trek: Generations)

The Breen also manufacture a portable hand held cannon, the CRM 114. It was designed to target moving objects and surface emplacements. It was among the weapons dealt by the Ferengi arms dealer Gaila in the mid-2370s. (DS9:"Business as Usual")

Background Information
Although it is impossible to tell the gender of the Breen, Cathy Debuono was one person to wear one of the suits.
The model for the Breen suits came from the Ubese Bounty Hunter suit that Princess Leia wore to Jabba the Hutt's Palace. The Breen helmet is reminiscent of that worn by Princess Leia in Star Wars Episode VI: Return of the Jedi. It has been speculated that this was intended as a tribute to Star Wars' 15th anniversary, though it should be noted that both the Breen and Boushh are very similar to the Cylons from the original Battlestar Galactica TV series.
In Norwegian, the word breen means the glacier.
Executive Producer Ira Steven Behr has said that the Breen's distinctive, scratchy voice was inspired by the guitar feedback on Lou Reed's album "Metal Machine Music".

[the Fifth Race]

Breen does mean Glacier in Norwegian. If you read through the article I post iy will shed a lot of light on the Breen and misconceptions.......

Interesting, I knew the word was Norwegian but I wasn't sure of the meaning.

The Breen may have been influenced to join the Dominion from a Changeling impersonator in the Confederacy's government, as an unidentified Breen was seen in Internment Camp 371, where several people replaced by Changelings were placed.

Wow, that makes an awful lot of sense. I always kind of wondered why there was Breen in the prison. They hadn't joined the Dominion alliance as of yet so a Changeling probably did infiltrate the Breen Confederacy and influenced them to join the Dominion with what we later found out were false promises from the Founders.

Shortly after joining with the Dominion, the Breen attacked Starfleet Headquarters on Earth in the raid on San Francisco.

Those suit wearing baztardz! I drive across the Golden Gate Bridge to and from work 5 days a week, and I can't help but think of Breen attack, the ending Voyager where I believe Voyager flew underneath the bridge and the movie The Voyage Home where the Klingon bird of prey flew over it.

I think it was the other way around Brother Fifth, the BOP went under the bridge and Voyager flew over it. I could be mistaken though.

I think the Breen are a cool and mysterious enemy that I hope are explored in the new Trek series.

[the Fifth Race]

I think it was the other way around Brother Fifth, the BOP went under the bridge and Voyager flew over it. I could be mistaken though.

You are right brother HG, after I posted it and thought about it, I realized it was the other way around. The Bird of Prey flew under a fog shrouded Golden Gate Bridge, Voyager flew over with fireworks in the back ground and the Breen just plain destroyed it.

I think the Breen are a cool and mysterious enemy that I hope are explored in the new Trek series.

I agree, the Breen are still very mysterious and very powerful.

Season VI of DS9 episode discussion
Episode # 17

Wrongs Darker than Death and Night
On her late mother Meru's birthday, Kira receives a transmission from Gul Dukat in which he tells her that Meru, who supposedly died when Kira was three, was actually his lover for many years and left her family to be with him. When Kira's investigation fails to prove Dukat false, she asks Sisko, as the Emissary, to permit her to consult the Bajoran Orb of Time. He agrees, and Kira finds herself in the past, at a refugee center where she comes face to face with her long-lost family, who does not realize her true identity.
Kira and Meru are taken from the camp to become "comfort women" for Cardassian troops. The sight of her mother being torn from her children is painful for Kira, and she vows to help her return to her family. The women are taken to the Terok Nor space station, where, despite her sadness, Meru is overwhelmed by the bounty of food and other comforts. Later, she is singled out for special attention by Gul Dukat, the Prefect of the station.

Meru confesses to Kira that she has what she always dreamed of — enough to eat, beautiful clothes — but at the cost of her family. Later, Kira learns that her mother has become Dukat's mistress. When Kira confronts a guard and demands to see Meru, she is thrown out into the station's Bajoran ghetto.

Kira befriends a Bajoran named Halb, who asks her to help attack the Cardassians, but she is suddenly summoned to meet with Meru. When her mother begins singing Dukat's praises, it is too much for Kira to bear. She angrily reminds Meru that Dukat is not only responsible for killing innocent Bajorans, but also for separating her from her family. Meru explains that Dukat has promised to provide her husband and children with food and medical supplies. Kira accuses Meru of becoming a collaborator and storms out, hatching a plan with Halb to smuggle a bomb into Dukat's quarters. The blast will kill her mother, but Kira no longer cares.

Pretending to have had a change of heart, Kira returns to Dukat's quarters to apologize to Meru, then secretly hides the bomb. She is preparing to leave when Dukat gives Meru a recorded message from Kira's father. He thanks his wife for what she has done, telling her that she has saved their lives. Kira realizes that if her father could forgive her mother, she must forgive her also. She warns Dukat and Meru about the bomb, and they escape just before it detonates. Kira returns to the station with the painful knowledge that Dukat's story is true.

------------------------------------------------------------------------------------------------

Wrongs Darker than Death or Night was a much better episode than I remembered. Maybe it's just that I am sucker for anything that's Kira dedicated but this episode was very well acted, even though the story left a lot to be desired. There are few notes I made......

As far as the time travel question goes, I'm not convinced that the Orb of time works the way we have seen other time travel. I don't believe that Prophets would send you anywhere unless they knew what your actions would be before hand, they would not send anyone that would alter the time line, or they would stop anyone from accidently changing it.

DuKat is as arrogant and obsessed with self image in the past as he is currently in the DS9 time-line. He tries to convince everyone around him (especially the Bajorans) that he is all for there well-fare and his actions prove that to be the case , anotherwords you could see his mental illness even at his younger age.

This is an interesting piece of info about this episode from Ira Steven Behr......This episode was originally going to feature a past affair between Dukat and Major Kira, but Nana Visitor argued with Ira Steven Behr against it. When the script came out, Ira happily informed Nana that the affair wasn't in the script, and that she never had an affair with Dukat, and smiled, "but your mother did...." LOL, even Nana Visitor couldn't stomach the possibility of Kira being romantically involved with DuKat.

Memorable quotes from the episode......

"I only hope you won't condemn us all for the boorish behavior of one man."

- Gul Dukat to Kira Meru

"Mind telling me what you're smiling about?"
"The Prophets - I never realised they had such a sense of humor. When I was a child, I dreamed of having food to eat and pretty clothes to wear, and now look at me - I have everything I ever wanted and now look at me."
"That is pretty funny in a horrible way."

- Kira Nerys and Kira Meru

"I know what you're thinking - you can't wait to get us all drunk so you can kill us in your sleep."
"Are you sure you're not part Betazoid?"

- Cardassian and Kira

"You Bajoran women are so bony."
"That's because you Cardassians eat all our food."
"I could have you executed for that kind of remark."
"And that's why we hate you all so much."

- Cardassian and Kira

I re-watched this episode over the weekend and I must say it was a pretty good. I don't know how they did it, but they did make DuKat look younger in the "back in time" scenes. You are right brother Fifth, DuKat was much the same back then, trying to convince the Bajorans he is on there side, he is doing more for them than any Cardassian before, while he takes woman away from there families to be prosititutes for the Cardassian military. I guess mental illness or meglomania isn't a prerequisite to not be a commander in the Cardassian army.

As far as the time travel question goes, I saw it the way you did. I firmly believe that the Prophets send you back as an illusion so to speak, sure the events are real and did occur as they are presented, but you just an observer that cannot and will not be allowed to alter anything. Whether the Prophets know this before they send someone on a "Time Orb Quest" or whether they prevent it at the time of the incident, I do not know?. Sisko did mention and Kira alluded to the fact that the Prophets do not send just anyone on a "Time Orb Quest", you have to be accepted first by the emissary's blessing then you have to look into the Orb to see whether the Prophets send you where you seek to go. Very interesting stuff.

Kira was brilliant as ever, and even though Sisko and DuKat had small parts in this episode, they both shined as usual. I always find it interesting to watch Sisko deal with his emissary duties while juggling with beliefs and duty to Starfleet.

LOL, even Nana Visitor couldn't stomach the possibility of Kira being romantically involved with DuKat.

I can picture the first time Nana (Kira) read the script where she had an affair with DuKat in the past, she probably threatened Behr's life. Although I'm pretty sure she wasn't that much happier about her mother having the affair.

I will give Wrongs Darker than Death or Night 7.5 stars.

[Descent]

I really liked this episode even if Dukat mysteriously calling up Kira to tell her about the affair was a bit...out there. A lot of this episode proved what Sisko uncovered about Dukat in Waltz.

He's not the "good" man forced to bad things. He's a horrible man forced to do horrible things and that's all there is to it.

Another thing pointed out is that the whole time travel thing bugged me along Sisko allowing Kira to use it. Hmm, plot devices, oh well.

I really liked this episode overall and I always enjoy a good episode that looks back at the Occupation.

I give Wrongs Darker than Death or Night an 8/10

DuKat is an evil rat that jumps at any chance to get under Kira's skin, he is very sadistic and makes no bones about it.

Another thing pointed out is that the whole time travel thing bugged me along Sisko allowing Kira to use it. Hmm, plot devices, oh well.

Sisko didn't let Kira use the Orb of time per se, what he said was, it isn't a good idea to use the Orb of time for anything and he was afraid that Kira would try to alter the time-line. To which Kira said that she asked him as the emissary not as commander Sisko and that the Prophets would not allow her alter the time-line and she wouldn't be allowed to use the Orb if her quest wasn't worthy in the first place.

[Darkstar]

The Orb does send the recipient back in time, in the episode "Trials and Tribble-ations" the defient goes back in time and sisko and co work to save Kirk from being blown up by a faked bombed tribble in the storage hatch back in season 5.

Thats time travel I could be wrong but wasen't that the same Orb?

The Orb does send the recipient back in time, in the episode "Trials and Tribble-ations" the defient goes back in time and sisko and co work to save Kirk from being blown up by a faked bombed tribble in the storage hatch back in season 5.

But the end result was the same as if Sisko never went, the time-line stayed the same.

Thats time travel I could be wrong but wasen't that the same Orb?

It's all subjective, the Orb of time does not send someone physically back in time, your body stays in the present standing in front of the Orb. Your mind and conciousness are sent back in time as some one different but similar. IMHO I just don't see it as classical time travel where you are sent both physically and mentally in the future or past as yourself and as someone who could alter the time-line by accident or on purpose. The way the Orb of time works is different, the Prophets control everything, if they do not want to send you the Orb will not work, they control what you see, and they wouldn't allow any changes in the time-line.

[Darkstar]

Yo know and just out of curisoity in the pilot episode way back at the start when Sisko meets with the Prophets inside the wormhole for the first time he is recounting to his deceased wife Jen (who is a Prophet but in her image of course) and he tries to explain the concept of time and how humans and he precieves time because they exist outside time of something, so for an Orb of time is is a little contradictory in a way if they do not know time?

[the Fifth Race]

Here is some DS9 Tine Travel love for my fellow Trek Brethren....

Time Travel in Star Trek: Deep Space Nine (DS9)

"I hate temporal mechanics!" (O'Brien, DS9: "Visionary")

DS9: Past Tense..... Sisko, Bashir and Dax beam down to Earth, and they arrive at the right place, but in the year 2024. This transporter accident is attributed to chroniton particles from the Defiant's cloaking device, which misdirect the transporter beam. In the past, Sisko and Bashir meet Gabriel Bell, which is supposed to be an important man in history: To Sisko's knowledge, he is the man who avoids a massacre when homeless people take government employees as hostages. Bell, however, is killed prior to this incident when he tries to protect Sisko and Bashir. His premature death changes history, and the Federation ceases to exist in the future. The Defiant is not affected by the timeline change due to the chroniton particles on the ship's hull. Dax, Sisko and Bashir are obviously protected as well, since they continue to exist in the past and have memories about their future. Therefore a paradox is not due in this episode. Nevertheless, predestination does not apply in this case, since the timeline was definitely temporarily changed. Sisko finally corrects the timeline by pretending he is Gabriel Bell, so it is not astonishing that his portrait will be depicted in history books (see DS9: "Little Green Men"). Anyway, why did no one except for Nog notice the striking resemblance of Sisko and Bell?
Classification: past incursion, corrected with one visible consequence (Bell is now Sisko)

DS9: Visionary..... "Visionary" Miles O'Brien suffers from a radiation damage caused by delta type isotopes. In connection with the tetryon emissions from a Warbird's quantum singularity this is the cause for O'Brien's frequent time leaps.

1. While playing darts, O'Brien travels about 5 hours to the future, where he watches himself talking with Quark about a damaged holosuite on the upper level of the promenade deck. This situation causes the first (probably minor) paradox, since vice versa, while actually talking to Quark, he remembers his time travel and is aware of the other (time traveling) O'Brien who was not recognized in the first timeline. The fact that a temporal anomaly was found at the time of his departure and his arrival confirms that he actually traveled through time and did not hallucinate.

2. O'Brien travels to a turmoil in Quark's Bar, again about 5 hours in the future. An obvious paradox does not occur, since the turmoil takes place anyway, despite the improved security measures. The two O'Briens help each other struggling against the furious Klingons and Romulans, still, the scene is slightly different in the second timeline.

3. O'Brien witnesses his own death when he is hit by a laser beam in front of the Romulan quarters 5 hours later. This time the timeline is definitely and significantly changed, since the accident is avoided.

4. Once again poor O'Brien travels to a time when he is dead, this time because of an irreversible brain damage. The future Bashir tells him that his basilar arteries should have been scanned in time. Back in his present, Bashir does so, and O'Brien's life is saved in the new timeline.

5. Things get even worse when DS9 has to be evacuated and finally explodes, and the wormhole is sealed. O'Brien witnesses these events in the future, but he fails to find a clue. Although it might endanger his life, he decides to attempt an intentional time travel in order to prevent or at least find the reason for the disaster. This is accomplished by flooding his body with delta isotopes and calibrating their time constant in a way that this time travel leads only 3 hours to the future.

6. The calibration being very inaccurate (at least for Star Trek standards), O'Brien arrives 3.5 hours later, just an instant prior to the evacuation of the station. Still, it is enough time left to find out that a Warbird destroyed the station along with the wormhole in order to prevent a Dominion invasion. Since the time traveling O'Brien suffers from severe radiation damage, he gives the time travel device to his future self.

This episode implies multiple paradoxes, unless we assume that the timelines in different times are isolated from each other. Only in this way it is possible that O'Brien repeatedly prevents his own death, which would have occurred anyway in a predestined timeline, and the prevention of which would have lead to a causality loop or paradox in other theories. Most obviously, the O'Brien who remains in the present, is an O'Brien who has memories of a timeline which is supposed not to exist any more.

Anyway, it is more annoying that highly qualified Starfleet personnel (namely Jadzia Dax) is not able to identify a "black hole circling around the station" as a cloaked Warbird. At latest since TNG: "Timescape" it should be a commonly known fact that the Romulans employ a quantum singularity as power source.
Classification: multiple travels to the future, accidental and to avert future disaster

DS9: The Visitor..... Some time in the 25th century, a young woman visits old Jake Sisko and asks him why he stopped writing a long time ago. Jake tells her that he lost his father in an accident on the Defiant many decades ago. At that time, Ben Sisko disappeared to subspace, and since then reappeared on rare occasions, always in the vicinity of his son. The title of the episode is ambiguous and may refer to the young woman as well as to Ben. While Jake first tried to cope with this situation and became an author, he later turned to science and took any effort to get his father back. Finally, the situation is resolved, when old Jake dies and the bond between him and his father is torn. Back on the Defiant, Ben is warned in time, and the accident is avoided.

Obviously there is a biological effect involved, a connection that keeps Ben in subspace as long as his son is alive. Even if we accept this odd biological component of the inherently physical traveling from one space-time to another, the solution is not consistent. First, there is a clear paradox when the accident does not occur again at the end of the episode. Second, there is no clue why Ben is thrown back to an instant just prior to the accident. This appears to be a kind of divine intervention.
Classification: alternate timeline which ceases to exist, remaining paradox (Sisko's accident doesn't occur)

DS9: Little Green Men..... Quark and Rom accompany Nog on his way to Starfleet Academy, when their shuttle "Quark's Treasure" is thrown back to the year 1947 and crashes near Roswell, New Mexico. In this odd story the three Ferengi are responsible for the so-called Roswell Incident, which many people in our time believe to be authentic. This Star Trek plot can be regarded as the third one based on a predestined timeline after TOS: "Assignment: Earth" and TNG: "Time's Arrow". As if he knew that the future is not endangered, Quark seizes the chance to sell 24th century technology to the "Australians" (or Americans, what does it matter), which could dramatically change Earth's history. In contrast, his nephew Nog tries to avoid any damage to the timeline. His threat that Ferengi Marauders would attack Earth is a good idea in this respect, since he tells the 20th century humans exactly what they expect to hear. Besides, at the beginning of the episode Nog holds a PADD in his hands where "Gabriel Bell" Sisko is depicted, which reflects the timeline change in DS9: "Past Tense".
Classification: past incursion, with minor consequences (Roswell Incident)

DS9: Accession..... The injured Akorem Laan stumbles across the Bajoran Wormhole with his sailing ship around 2172. His wounds are healed by the Prophets. Akorem emerges from there 200 years later, possibly because of a "mistake" by the Prophets, who are not aware of the linear nature of time. In the 24th century, Sisko and Akorem struggle for the position of the Emissary, and they enter the wormhole to let the Prophets decide. When Akorem learns that he is not supposed to be the Emissary, he agrees to be sent back to the time when he first encountered the wormhole.

The Prophets promise to send him back healthy, but without a memory of anything that happened. The timeline would have been changed at any rate, because Akorem travels to a past in which he was believed to be dead. He finishes a poem that Kira remembers to be incomplete. While we may suppose that he didn't finish the poem the first time simply because he was stuck in the wormhole, the question occurs why of all people Kira should not be aware of the now different history. But as Sisko himself suggested, the Prophets may have intentionally left this little conundrum.
Classification: past incursion with minor consequences

DS9: Children of Time...... The Defiant crew members are surprised when they discover a planet which is inhabited by their own descendants from a changed past. The "Children of Time" know that when the crew tries to leave the planet the Defiant will cross a temporal barrier. The ship will be thrown back in time and crash land on the planet, leaving no possibility to escape. The question arises whether it is right to allow the time travel in order to preserve the people on the planet, or to take countermeasures to get home. Sisko decides to let things happen and orders a course towards the temporal field. However, the older version of Odo, who spent the whole time on the planet mourning for Kira who died without medical treatment after having suffered a plasma shock, prevents the time travel. History is corrected, and the small colony on the planet ceases to exist. Still, the crew remembers them.

The Defiant crew descendants are there without actually a time travel to the past occurring. This should be a clear sign for predestination, and in this case it would have been the last DS9 episode, leaving the Defiant crew trapped in the past. Yet, the timeline is altered when the Defiant finally escapes. So this episode features a strange and inconsistent mixture of causality concepts. The odd phenomenon of breaking an existing causality loop is similar as in VOY: "Time and Again", and cannot be solved. Still, here the original timeline in which the "Children of Time" live on the planet is not just erased, since they are still remembered after they have disappeared. Everything on the planet did actually happen and, most importantly, Kira gets to know that Odo loves her.

By the way, Sisko's decision to let the time travel happen is highly doubtful in three respects. Firstly, from an ethical viewpoint it is equivalent to abandoning his duty and family intentionally and condemn his first officer to death. Moreover he orders his crewmates to do the same. Secondly, the fact that the crew have learned about their future in the past will almost certainly change the history of the planet, considering various possibilities of female/male relationships that cannot be controlled and could develop in a completely different way. In this case the known descendants might never come to existence and the sacrifice of the Defiant crew in favor of them would be useless. Thirdly, even if we accept that the timeline with the Defiant crashed on the planet is the original one, it is created involving a time travel, and this is not possible in the natural course of time. In this respect it is generally the right decision to alter history in a way that the time travel and its effects are avoided or compensated.
Classification: broken predestined timeline ("causality loop")

[the Fifth Race]

DS9: Trials and Tribble-ations The time travel is enabled by the Orb of Time, and this could be a sign that the protagonists are actually guided and protected by the Prophets, such as in DS9: "Wrongs Darker than Death or Night", where it is explicitly mentioned. In fact, the mission to prevent a change in the timeline is successful, and Kirk is saved without even noticing it. Amazingly the episode seems to be completely consistent with the events as shown in TOS: "The Trouble with Tribbles".
Classification: past incursion to change history, corrected

DS9: Wrongs Darker than Death or Night Kira's time travel is guided by the Orb of Time and therefore by the Prophets. It is not mentioned how the Prophets manage to protect the timeline or at least reduce the possible damage to a minimum. Kira would have enough chances to alter history, since she encounters her mother and also herself as a child. Finally, she even tries to kill Dukat and her mother, and it is not clear if the Prophets would have avoided the bomb explosion, if Kira had not done it herself. It is possible that Kira's time travel lead to an isolated past which had no impact on the present. Still, it is not very fruitful to discuss the capabilities of supernatural beings who exist out of time and can manipulate time as they like it.
Classification: intentional travel to the past, without visible consequences

DS9: Time's Orphan Eight-year-old Molly O'Brien travels 300 years to the past when she falls into a time portal. The DS9 crew manages to reactivate the destabilized portal and get her back. However, due to an instability in the temporal field Molly comes home 10 years too late. She is now an 18-year-old girl, who has spent the past 10 years of her life alone on an uninhabited planet and is run wild. Nevertheless, the O'Briens decide not to alter the timeline again, since the existence of their older daughter would be extinguished, if they tried to get her back at the age of eight. When Miles and Keiko finally decide to send her back to her home in the past, the time portal works properly again and she arrives at a time 300 years ago instead of the intended 290 years. So Molly meets herself as a little girl, and persuades her to cross the time portal towards the future. At the same instant, the 18-year-old Molly vanishes, since she has never existed. Still, Keiko and Miles do remember her.

The net time travel is that of 18-year-old Molly ten years into her past. In this respect it didn't matter whether the time the portal sent Molly to in the first place was in the future or in the past, as long as no interaction with the present was possible. The obvious paradox in this story can be solved, if we postulate that the time portal has an isolating effect, allowing that different timelines exist on its two sides. Moreover,

But the end result was the same as if Sisko never went, the time-line stayed the same.

Not entirly.....Kirk made his pretty lady smile at him instead of the pretty lady. There's a change.

It also automatically makes minute changes in the crew members' behaviour patterns- they just say hello to one of the DS9-ers, from there all their actions are off minutely, even if they follow the same course of business that they would have. So while the big picture ended up the same, many little pictures were altered, and when it comes to the cosmic scale of the universe, there isn't much difference.

I understand the small changes that occured when using the Orb of time, we witnessed those in this last episode brother Fifth put up "Wrongs Darker than Death or Night". But in all the Orb of time episodes the time-line stayed the same in the end, which leads me to believe that either the Prophets are just presenting an interactive hologram type rewind or more likely the Prophets know exactly what is going to happen before "the chosen" people that view the Orb will not change the time-line with there actions.

You are making think way to much about this TrekGirl.
