There was a definite cheer let out in the room when that happened.

It seemed like it never occurred to him that he should be talking to the baby (he probably had no experience with kids) until she told him. Then when he started to do it, he realized it wasn't as awkward as he thought it was going to be. I really liked that scene too.

I didn't read it like that at all. I believe that she wanted her back in jail so she would have her fuck buddy back (she kept flashing back to their first sexual encounters). Plus, she was genuinely worried about Alex's safety. She just told Polly that she would be screwing her over in order to making her do it.

They way I interpreted the scene, the "mail fraud" was a red herring and she was actually convicted for stalking.
