The way Pan called Rumple, “laddie”. I’ll bet that’s what their father used to call him.
Yes! That sounded so much like an older brother talking to his bullying victim…. er… younger brother.
Also, the Rumple/Bae conversation back at their hut after Rumple magicked him out of there. I’ve known him since I was young etc etc.
Serious psychoanalytical gold mine though: exactly what did Mama and Papa Stiltskin do SO WRONG for both sons to end up dark, twisted, abusive magical overlords?!!
