Student nurse at Memorial Hospital
Doesn't matter what it is, the safe money says that Alison has been there, done that. Go ahead, try her. Porn star? Check. Junkie? Check. Sends Mother's Day cards to her sister, Emily? Check. Yep, she's done it all. And if you're talking about sleeping with the same dudes as your mother-slash-sister, she's done that MORE than once.
The funny thing is, Ali isn't a bad person. Far from it. Despite some serious baggage (especially in the L-O-V-E department), if you saw her being lectured by her mom-mom (as opposed to her sister-mom), Dr. Susan Stewart, you'd probably think she was the girl next door -- and no, not the girl next door to a brothel, either!
