Yeah, I completely agree with you. At some point she’s bound to find out and she’ll begin to hate Jefferson. The only question is, does she find out before or after she strands him in Wonderland? From what we say in Hat Trick, she didn’t seem like she had a whole lot of animosity towards him, but was more manipulative than anything. Then we find out that she made his curse different than everyone else’s by causing him to remember. So, either something happened between the events in Hat Trick and the casting of the curse, or Regina is a really good actress to hide her hatred for Jefferson and not even tell him about it as she strands him in another world.
Yeah, I’m going with something happens after she strands him.
