I don’t think Tink is anyone’s fairy Godmother she is just a fairy like the BF was in my opinion.
All the fairies we have seen have had the jellyfish dress. Varying embellishments and colours, but all the jellyfish design, like Blue’s. When that swarm of fairies attacked George’s castle, it was jellyfish everywhere. The only exception has been Ella’s FGM. And now also Tink. Unless and until we see other large populations of fairies without the jellyfish dress, I think that the only fairies who get to be distinguished with a non-jellyfish costume, are FGMs.
Everyone’s thinking that it’s either Blue or Regina that banished her to Neverland. I personally think it’ll turn out to be Cora.
I don’t have a theory why yet, but it seems like something Cora would do.
Totally something Cora would do if Tink was starting to get in Regina’s ear. No one is allowed to tell Regina what to do if they’re not Cora, so Tink would have to be removed.
