I would love a Belle/Rumple reunion 😀 If he is reunited with her, I think we’ll start to clearer sides: who’s with Emma breaking the curse and who’s with Regina. I think Gold would choose Emma’s side.
I think it’s likely David will remember his FT past but I hope if he does, that he won’t have his heart crushed like poor Graham.
I don’t think the curse will be broken by the finale.
