Cherry was in a state of shock that Scott found out the truth in the worst way possible and didn't leave her over it. That whole conversation was a lot to process.
He managed to guess what she was up to solely from finding out that Sherry and Delia were the same people. That was a crazy level of deduction but it made a bit more sense after finding out he saw what she did to that creep who attacked her several months ago.
It was strange finding out he was so nice to her because he didn't want her to end up like him. Even stranger that he had met her father in prison. Talk about a small world! She couldn't help but wonder what he had been in for but didn't feel like it was the right time to ask since he was still understandably kind of mad at her.
Yet he was offering to take care of her once she got out of the hospital anyway. She knew he was nicer than anyone else she had ever met but wasn't this too much?
