I didn't catch last night's episode, but I watched the first episode of the season and can't help but feel all of last season was a waste of time.
They spent all of last season constructing a weapon, taking out the defense grid and then taking out Karen only to all get split up and turned into refugees in the current season?
I also lol'd at the "Don't you recognize your sister, Ben?" from Lexi. You went from a hispanic looking little kid to a blone, white teenager. No shit he doesn't recognize you.
