I think that it has to be Belle in the real world and not the fairytale world because we know that Rumpel is not aware that Belle is alive as of now so i think that may mean that something happens where someone finds out about Belle. Though we may just hear a conversation between Belle and Regina. There are a lot of possibilities. Though i do not think that we are going to have a happily ever after for Belle and Rumpel. For some reason i don’t see that happening at least not long term.
