Lost: I forgot it takes them a few episodes to get back! The whole time Greer was running towards the Stargate hoping to get there before Eli, Scott and Chloe left I was thinking FIRE YOUR WEAPON! That would get their attention and they wouldn't leave until they found him.
Could have done without the whole Greer back story which is just kind of shitty and cliched. Oh tough guy, had a bad dad etc.. I like Greer just fine, I think he's a very interesting character, and the backstory does nothing to make him more interesting.
Speaking of terrible dads, poor T.J.
Nicely done, the beginning of Chloe's massive brain hiccup. Other than the Greer backstory the drama of trying to connect the team with the ship and Greer being left behind works well. Would be nice not to always interrupt these people with earth stuff.
