I actually just looked this up and found out some interesting things.
Young MacGuffin speaks in a North East Doric dialect which obviously is hard to understand. Originally he was going to just speak gibberish but his voice actor, Kevin McKidd, suggested he try a few lines in Doric and Pixar loved it and kept it. Found a couple translations too, but only one of them applies to this gif set and that’s the third one after Merida gave her speech about letting them choose who they marry:
“It’s just not fair making us fight for the hand of a girl who doesn’t want anything to do with it. You know?”
So I know we know nothing about Pan’s back story, but until we do I feel like he came from an abusive household. There were no positive adults in his life and he was horrified of growing up because of that so he ran away to Neverland. And then he meets Hook who is an adult, but he’s the first adult Peter actually tolerates and then later likes and kind of trusts (even though he’d never admit those last two).
