It HIGHLY doubt it will be Emma, she’s only just after accepting that she cares for Killian at the moment. She won’t be ready for a wedding by the end of the season. You could be right about Regina – who knows what sort of development has happened between her and Robin in the past year? But at the moment, I’m thinking it’s likely to be Rumbelle. Belle isn’t that important no, but Rumple is.. I liked Belle in season 1 and some of season 2… but this season I’m pretty meh about her. She hasn’t had any real character development to me. Her reactions to Rumple’s villainy are all over the place – Neal has been mentioned TWICE as Rumple’s Happy Ending, not Belle. Neal has been more important to Rumple throughout the series so far, which is very consistent with Rumple’s character arc.
