I hope so, when they first announced that it had been picked up there was no suggestion that it would be mid-season only, so I'm kind of bummed about this :( People are saying in the comments that the writing will be tighter with only 13 episodes and that this is a good thing, but I actually found season 2 even stronger than season 1, so I don't know that it's a show that will necessarily benefit from a shortened season when the main arc tends to be quite involved. I remember hearing that they assumed that they were getting 22 episodes for season 2 originally, and so they had to cram everything in to the final episodes a bit/cut out some character scenes which dealt with Liz's family, so it sounds to me like 13 episodes isn't going to be enough to fit everything in

16/17 episodes would be okay, but I'll be disappointed if it's only 13
