I like the idea of this connection. It would make sense if the BF banished Tink to NL due to her relationship with Belle’s father. Also, it would explain why the BF is so against fairies being in love. Their has to be a reason behind this and I believe the BF said it distracts them from their duty. So maybe Tink was to guide Maurice and fell in love with him instead, had Belle and something horrible happened as a result. His kingdom and people fell prey to disaster.
Remember all the dad’s look better when they were younger. Remember Regina’s father was quite the looker in FB’s.
It would also explain why Belle is able to do the spell to protect SB, she has magic within her.
