Heartwarming / Return to Never Land

• Although it is followed with a huge Mood Whiplash, "So to Be One of Us", with Jane playing with the Lost Boys and Peter. Although it doesn't go well at first, she eventually is shown laughing and having fun, and finally acting like a kid—which, considering that Jane is a huge Broken Bird who was forced to grow up way too fast during the Second World War, is very sweet to see.
• The scene near the end when Jane's renewed belief in fairies restores Tinker Bell to full health. Tink sees Jane crying, she smiles benevolently at the girl and gently tugs at her hair to get her attention.
• The scene with Peter giving Jane a flying tour through Neverland, which starts with them flying over a rainbow and Peter taking Jane's hand to run both their hands through it. Though Jane is initially scared, she genuinely seems to be enjoying the experience (at least until Tinker Bell tries to push her off of Peter so she'll fall), and Peter, for his part, does seem to be making sure she's having a good time. Peter also saves Jane from being soaked by the mermaids, indicating he remembers Wendy did not like that. Considering how dismissive he was about it in the first film, it says a lot that he understands now that it was not a pleasant experience for Wendy and doesn't want Jane to go through it.
• Jane telling her baby brother about her adventures in Neverland, showing her restored faith in fairy tales and making up for her bitterness in the opening of the movie.
• In a similar demonstration of Took a Level in Kindness, Peter stares at Jane sympathetically when he finds out why she's so desperate to go home, and when her makeshift raft sinks, he's willing to teach her to fly so she can return. Later, when he finds her again after she becomes fed with their shenanigans, Peter quickly apologizes for what they did and states they want to make her feel like she's one of them. It's quite the change compared to how dismissive he was of Wendy in the first film.
• Wendy's brief, but beautiful reunion with Peter and Tinker Bell at the end. She may have grown up, but deep down is still the girl she used to be. Tink even levitates her for a moment to let her relive the sensation she felt years ago.
• Just the final minute of the film is packed heartwarmers. After Peter and Wendy say goodbye, her newly-reconciled children come to the window and Danny gets to glimpse Peter for himself, just as her husband returns from the front to Jane's absolute joy and relief. Peter and Tinker Bell watch the Darlings' reunion with satisfaction before returning home themselves. The booming Triumphant Reprise of Peter's leitmotif from the first movie puts the cherry on top.
