So does that mean you think Sam would lose her personality if she ever got together with Jack? I suppose I can see that happening, given how the SG-1 writers treat the pairing. In fanfic it can be okay, but canon is iffier. I'm not saying I like Sam/Jack better, just that it doesn't bother me, while Lee/Laura does.

Honestly, I think that Sam's canon feelings have already compromised her as a person. That's a large part of why I don't like her as much as I'd like to. I hate that she made the bomb in Scorched Earth, knowing that Hammond would be against it and knowing that she personally felt it to be the wrong thing to do. But Jack wanted her to, so she did. I hate that so much. I hate the way she acted in Threads. I hate that when Jack gave command over to her in The Lost City, her first action as a commanding officer was to push Jack to talk about his possible feelings for her. I hate her saying to her Jack-vision in Grace that she would leave the military for him.

Putting the two of them in a relationship wouldn't tarnish her, because she's already shown that her feelings will get in the way. It would tarnish Jack, who has thus far managed to walk a very thin line.
