So ... season is only a few episodes old, and we already have an episode without Samantha Carter, and I didn't miss her. (Did anyone?) I thought Shepard and the Traveler leader had some good chemistry, I guess now that Weir is gone they had to give him someone to be quasi-romantically interested in, even if at arm's length. I think there's a good chance we'll see her again this season .... I'm just not convinced that the prospect of a future alliance was enough to allow her to let Shepard go - she could have held him, especially given how important it was to her to get the Atlantean ship fully operational, but I guess that's just a minor plot nitpick.
