Disney Fairies/WMG

Tinker Bell is much more intense and animated in everything that she does after she leaves with Peter Pan because she has more to lose.

In Pixie Hollow, she was around others of her own size, language and culture. When she is with the Lost Boys she is forced to make every emotion more obvious because she is barely there to them. She also becomes more spiteful and jealous because she left everything to be with Peter Pan, and has that much more to lose.

• • The movies does take place before the Peter Pan movies. Tink is shown to have affections for Peter, so that might count as Love Makes You Evil.

Queen Clarion and the Minister of Spring are having an affair.

Hence he tries hard to impress her and is so nervous around her.

• • Sounds more like a crush than an affair...
    • Seconded.

The Pixie Dust Tree is the heart of the island.

And Peter is the island's protector.
