That would make a LOT more sense! Thanks! Thought I was going crazy trying to track the cuffs, but that would explain why Regina thought it would be safe to wear and how Pan conveniently had a loophole!
So that means Cora had them at some point that Regina would recognize them, she put a spell on them for the beanstalk, and after the beanstalk is when they were messed with by GOAT sending them to Pan. Hook at least has that impression I guess since he said “they rigged it” and obviously they wouldn’t know there was magic in it since Pan was manipulating them and told them whatever they needed to hear.
I thought I might be over-thinking something but Pan’s been playing such a long game it made me wonder!
