Heartwarming: A Fairly Odd Movie: Grow Up, Timmy Turner!
While the canonicity of the film is very debatable, Jorgen (and the rest of Fairy World for that matter) ultimately allowing Timmy to keep his fairies, on the condition that he continues doing good deeds with their magic. It's certainly a big contrast with how often he was called selfish in the animated series. Hell, Jorgen once out-right stated that the world would be a better place if he didn't exist! It was also nice to see how grateful everyone in Fairy World is of Timmy's good deeds in the past.
