I’m anxious to see Mr. Gold reunite with both Belle and Baelfire. That man needs a reason to become good again. He needs living proof of his goodness, and Baelfire and Belle are those people. Hopefully, Mr. Gold will be able to prove himself and become the loving father he once was.
Or maybe he needs to become good again before he reunites with his loved ones, so they will see the change and forgive him. To do something selfless, even self-sacrificing, and aboveboard would be a great first step. If he can find himself again he’ll be ready to find Bae and Belle.
