Hook/Tear Jerker

"Wendy: "Hello, boy.""
 * Wendy's very first line, especially when she fully expects Peter to remember based on that alone.

"Jack: Please don't give up."

""I wish I had a dad... like you.""
 * "When You're Alone". Even the pirates get teary over it, save for Hook, who looks more like he doesn't know what the hell is going on.
 * He may have left so no one can see him cry. And his last words were "I want my mommy!"
 * Remembering Childhood.
 * The entire scene where Peter regains his memories, starting with, "I remember..."

"Peter Banning: Tink!

Tinkerbell: Say it, Peter. Say it and mean it.

Peter Banning: I believe in fairies.

Tinkerbell: You know that place between sleep and awake? That place where you still remember dreaming? ... That's where I'll always love you... Peter Pan. That's where I'll be waiting."
