Let me get this straight--
It was the kids who drove her to drink in the first place. so, when she gets arrested for drunk driving, she gets knocked up again? and this is after the shit hit the fan and she knew she was probably going to jail? My guess is moomy and Duhddy thought that "nobody would be so heartless to put a pregnant lady in jail!" Sorry. And let's say she didn't go to jail. In another couple of months she would have put somebody else in the hospital because now she would have four kids driving her to drink.
Yes. That sound you heard was my head exploding.
