I had figured that Alison was so big because this is baby #2 so she's showing earlier (a lot of women do show earlier and bigger with subsequent babies) but then I did the math, realized that she's got at least 21 weeks left to an April due date, and thought ... what woman shows like that at 19 weeks?
I reiterate my contention that Alison needs a posse of girlfriends. Having one friend you haven't seen in nearly a year and an ex-sister-in-law are not good. She needs a crew of women who can call her out on her ongoing series, Bad Decision Theater.
Then again, if Alison had a crew of good friends, maybe she wouldn't have been so mired in helpess grief and self-loathing back in S1.
This show is pretty much an argument for why, even if you have a romantic partner who rocks your world, you really need good friends. Not family, but good friends. Everyone whose POV we see on this show is so very alone.
