I don’t expect it to be a happy reunion. When Milah left with Hook, the only thing Bae knew at that point was that his mom died. I doubt Rumpel went home and said to him, your mom took off with a pirate. No. And when Hook and Milah came back to the same port, Bae was already long gone by that point. So, I can see Bae being sympathetic to Rumpel about his mom – why he was mad with her. That may sway him towards his side a bit, but not all the way.
I’d like to see them trying to reconcile over a long period. Not, I’m sorry son that I abandoned you over one episode. I would hate that.
