Seeing as how Peter Pan is evil, the mermaids are bad, I expect Tinker Bell to be more than rebellious but manipulative to the core. In the original PP, she was in love with Peter Pan and jealous of Wendy.
Agreed. It seems like the “native” inhabitants (we still don’t know if PP is native to NL) of NL are more devious and manipulative than people from other realms. But maybe there are exceptions to each of the species: Ariel, for example, being the “good” mermaid. Random brain thought: Blue was originally from NL but left because she wanted to be “good” rather than an evil fairy, like Tink? While I like Blue more as Sneaky Fairy, this might be another route they could go down.
