Maybe they met as children. We still don’t know how Baelfire spent the years between Neverland and growing up. He might have helped Gerda to get to Kai and save him, because he did know a lot about magic, travelling through worlds and all that stuff. The reindeer says it knows the way to his home. I guess the Snowqueen is from the EF. This would actually really work with showing flashbacks!
