You know I would find it interesting if for some times Belle end up with Keith (or anybody else) Don’t hit me Rumbellers please 
But it would be really interesting to see Rumpel struggle and, yes, suffer too. As much as I love him, he need to suffer. He deserve a little angst for what he has done to the Enchanted Forest and his inhabitants. For what he has done to Regina. To Bael and all the others he manipulated and screwed over for his own interest.
In fact I now hope Belle will not get her memory back until next season. Rumpel need to atone, understand and learn.
