It starts of with 'Michael' in the med lad, he's totally human & wakes up with complete amnesia. Weir & Shep come to him after being told by Beck that he's awake. They inform him that his name is Michael & he works under Shep's command as a soldier in Atlantis.
This goes on for a little while, he's told that he has diabetes & needs a daily injection to control it. Of course it's really his daily dosage of the retro-virus. They haven't refined it enough for the long term, some it needs to be administered every day to supress the bug part completely. The team have a meeting, which includes Beck & Dr.Heightmeyer. Those two along with Weir have support for releasing him as they think it will aid him in his recovery. Shep doesn't agree but he's overuled. So he's released & taken to his quarters by Teyla,. She shows him a cowboy hat & tells him he's from Texas. As well as telling him two people in a photo are his parents. He is sleeping (dream sequence now) then wakes up, he wanders over to the mirror & looks in it, suddenly it's a Wraith reflection that staring back at him. He wakes up from the dream in a cold sweat.
Next day, he's sparring with Teyla. Bits & pieces are starting to come to him now. Teyla beats him good in the first practise. She tells him that he is a good fighter & that he was a hero etc, he was on a mission before he was captured by the Wraith. So they restart & this time he gets the better of Teyla & throws her to the ground. Suddenly Ronon come in & grabs him & flings him back against the wall. Then without breaking rythm, picks him up against the wall by the throat in a supreme show of strength. Teylan screams that it's only training & to let him go.
He is talking to Teyla about the dream that he has had, she assures him that he isn't the only one. She has also had them as well as other members of the expedition who have came into contact with the Wraith. That calms him down a bit.
Later on, he's in the mess hall eating, he has two guards that are shadowing him everywhere. McKay comes past him holding a Tablet PC, he seems lost for words & they don't really know what to say to each other. While talking McKay turns the screen of the pc slightly towards Michael. Who immediately recognises the Wraith schematics that are on the screen as the materializer that's on the Dart, probably the one that was recovered from 'Duet'. He asks McKay how did he know that, he's told that he knows it because that was him mission when he was originally captured. Again he seems to believe it.
He's sleeping & has another nightmare, so he wakes up & goes over to the med lab to see Beck. He's there but is fast asleep, Michael galnces over at an exposed laptop (haven't they ever heard of power saving mode), he takes it along with a few other things & goes back to his quarters. He goes through the cd's on the laptop. Know he finally finds out that he's a Wraith. The team rush to him, he confronts them & accuses them of being hypocrites. It goes on about how evil the Wraith are & that he's better of the way he is know etc.
They take him for his treatment when he momentarily escapes, he ambushes & shoots a soldier dead before being recaptured. He's taken to the Atlantian holding cell that the other captured Wraith have also been held in.
The team meets to decide his fate, Ronon wants to kill him, McKay surprisingly agrees. Weir wa nts to continue on the drug with a stronger dosage to see what happens with that. So it's decided to move him to the Alpha site, they do that just incase a Wraith ship is flying close to Lantia & he connects with them & reveals all about Atlantis.
So he's knocked out & sedated for the journey. He awakes in the med lab on the Alpha site, a bit groggy but he's been restrained. He somehow connects with Teyla & gets her to help him escape his bindings. He takles her hostage & escapes into the woods towards the gate. Ronon & Shep are hot on their heels, he kills another 2 guards. He manages to dial the gate & get through as Shep & Ronon are right behind them firing. However they manage to get through.
They are about to call in McKay to strip the DHD down in order to get the last dialled locations. However Ronon finds a piece of tablet, that has gat sysmbols on it. Michael whose memory is coming back now must have wrote them down one symbol at a time to help him remember.
They are through when somehow Teyla is knocked out. She awakens a short time later, alone, her restraints have been cut off, as well as her vest. She turns around to be startled by a rapidly changing Michael, who is well on his way back to his true Wraith form. She senes that they aren't alone on the planet & that it's full of Wraith & they are coming to them. He says he knows & that's why he brough them there. She turns around to see a docked Hive ship, Cruisers are flying twoards it. There is a lot of activity going on. She asks Michael to go back & get his treatment. He tells her that he is going back to who he really is. She know knows that she's going to get fed upon, if not by him then by the Wraith who are on their way to them on foot. So she says to him that he may as well go ahead & feed on her. He walks over & puts his feeding hand slowly towards her, then suddenly pulls it back at the last minute. Teyla breaths a huge sigh of relief, but then just as quick, he fires the hand back towards her chest. Right then Shep & Ronon come blazing in behind them, they shoot him up pretty good. Then the Wraith reinforcements arrive, lots of the grunts chase them away. Then real Wraith come over to Michaels body & say he is still alive, they pick him up & carry him towards thr Hive ship.
The final scene switches back to Atlantis, they are holding an urgent meeting. They know he will tell all & know Atlantis' cover has been blown again. It's only a matter of time before they get to the planet again, McKay says that the cloaking act won't fool them a second time.
Then Shep says that they need some powerful weapons, then it ends.
Roll on, 'Inferno'. This is the one that I really want to see, since it has the Aurora Warship. Hope it isn't destroyed & they get to use it for the season finale.
