I don’t think Regina would need to brainwash Belle into hating Gold. What he did to her was enough for her to not go back to him. I wouldn’t go back to a guy who acted like. He is too erratic and completely flipped out and even though he felt sorry about it afterwards i really think he would do it again. I mean look at what he did to Belle’s father.
I disagree. I think Belle still had feelings for Rumpel when she left his castle. When we see her in the bar in “Dreamy,” she seemed to be genuinely heartbroken and sad about what happened to between her and Rumpel. I honestly think if Rumpel would have given to her and accepted her love, she would have stayed with him willingly, despite everything that happened between them.
