The plot itself was interesting. I liked the idea that they thought Jacob was dead. I was beginning to wonder if you had really killed him off until the wedding ring scene. Though the meaning of not finding it didn't seem obvious to Sam or Jack.
The characters were mostly "in character" as far as my understanding of them goes. I did have trouble with Jack's cold blooded murder of an unconcious Jaffa. I realize that with Jack's covert ops background that he would have that capability in him but I wasn't really prepared to see it (or read it). It also fit in with the "them or us" theme of the story but like I said I wasn't prepared for it.
I thought that Carter got a little too insubordinate too early. I could see it later on when they had been worn down by hunger, fatigue and dispair. The second day seemed a little too soon for her, though it could be attributed to grief for her father.
Okay, this is going to sound kind of stupid... I have a thing for how far into the mythology the writer goes into. I have a bad habit of "googling" names from an author's fic to see where they got there names from. Did you know that "Spegla" is a FTP software? LOL!
I loved the reference to the Duke! LOL! I have always pegged Jack as a John Wayne fan! The Duke will always be the best in my heart!
I liked the epilogue. Too often fics end too suddenly. "They were rescued. The end." I like to have a scene afterwards that finishes up the loose ends. That it included Teal'c's Ritual of Remembrance for Daniel was a nice touch.
