I just watched this ep and really enjoyed it, thanks for mentioning it. I am soooo going to have to watch all of SG-1 now. I loved the Daniel/Vala interaction.

Sam Carter is vaguely entertaining, but. I'm still extremely iffy about her coming to Atlantis :-/
I don't mind Sam Carter coming to Atlantis so much, I quite like her character, I'm just worried about what that means for Elizabeth...and the overall dynamic of the Alantis crew. Time will tell, I guess.
