Not only that, but she is also able to free Peter.
So that's what she was jealous of.
Tink distracts Hook and Smee while Jane frees the Lost Boys and battle the pirates.
This angers Tinker Bell, making her red with jealousy and even calling Wendy a "big ugly girl".

Though Emma is curious about what is her relationship with Tinker Bell, Regina would rather not go into details about the complicated history.
