Whitney went out of her way to see Scotty. I'm pretty sure her choice would have been B, especially since Cole had to practically hold her back while Scotty took off.

Alison definitely isn't a saint, but she's WAY more interesting than Noah. He always claims to want the best for his children but he doesn't even acknowledge them when they're around and they clearly have issues. At least Alison is less self-centered enough to see when something's wrong with the people around her.
