I agree with Slurpeez108 that a parent, especially Rumple, would cry over the toy of their child BUT 1) if that is Bae’s doll from when he was growing up we would have seen it by now. They could have used the ball we saw Bae playing with, they could have somehow used the shaw, something that audience instantly connects with Baelfire. But instead it’s a mystery as to who’s doll it really it is which is why I think it’s Rumple’s, it creates the mystery for the season (one of them at lest): how are PP and Rumple connected? What is their backstory/their history? And it’s more Rumple backstory. 2) The line from Felix is so…carefully constructed and needs so much unpacking that yes it’s psychological torture for Rumple buy probably on many different levels. The doll may remind him of Bae’s lost childhood because it’s also representative of his (Rumple’s) lost childhood. I think that doll is symbolic on many levels; it’s Bae, it’s Rumple, it’s Henry. A lot of our theories could be right (it belonged to Rumple as a child but it being used to torture Rumple over the death of Bae and loss of Henry) without being conflicting.
