I’m the odd gal out as I believe that this is not the end for Rumbelle. While there are lots of arguments supporting that it’s the end, and I agree with much that was said, I’m trying to think along the lines of A&E.
Rumple did something unselfish by returning Belle’s heart to her. He also acknowledged defeat and acceptance when he told her that Will is now the man to protect her heart.
A few things I noticed was the look of happiness when Rumple restore her heart and she came out of her trance and looked upon his face. She still loves him.
When Will reached for her hand, she didn’t reciprocate. She just doesn’t feel that way about Will.
As Rumple left the shop, she pulled away from Will and you could see the look of pain & love in her face for Rumple.
They directed that scene with very telling signs about how Belle truly feels about Rumple.
So, I say it’s not over and what Rumple did will allow Belle to open her heart and forgive him again.
