Inasmuch as most Salemites seem to be able to fall in and out of love quite easily, I am guessing Rafe could easily fall for someone else. But yes, people are going to be working on trying to get Hope out of prison, so she will undoubtedly be back.I just think, romantically, Hope needs to be alone and on her own for a while. She needs to concentrate on her family, and her job.
However, I do agree with Heather that the writing for these two has been all wrong. Might have worked for another couple, but Rafe had nearly his whole family move in with him, wonderful big family.......which has disintegrated and been ignored completely. That would not be like Rafe at all. He is very protective of his family, and was good at his job (when he was assigned to be Sami's guard in witness protection). But that person or trait has disappeared, and Rafe seems to hover and smother Hope at times.
And then Hope, her children have meant everything to her, yet she ignores granddaughter Claire, is unaware of daughter Ciara's inner torments, and barely even acted as though she knew Shawn, (when he was in town before).
So both have not been living as the Hope and Rafe of yore.
