Adrian, her old boyfriend; her former boss, Frank; or Jack? Sleeping around as much as she does, you'd think she would be on the pill. There is a rumor going around that sex can cause pregnancy!
shareMaybe she was on the pill.
shareI don't think it can be Adrian or Jess (her old boss) just due to timing. They don't make the timeline real clear, but I got the sense she was in town for a bit (the interview, the calls trying to set up interviews) before the New Year's Party and then there is a brief time from there to when she first sleeps with Frank. So it would seem it has to be Frank or Jack.
She pretty much lost me when Frank showed up and dumped the dog on her, and she not only took it, but then went off for a weekend fuck-a-thon as soon as Jack was out of town.
