I got about 3/4 of the way through the episode before realizing that Sam was taking the expedition leader role and I hadn't seen Weir at ALL. It surprised me, and I was REALLY pleased with it. She looks _good_ as a civilian with ex-military background! It's not so obvious when she TAKES CHARGE! And yet she's clearly facilitating all of it! Very, VERY snazzy. Sorta the leadership we always wanted to see from Sam....

(Am I correct in presuming she's now ex-mil, even though they're still calling her by her rank?)
