Interesting. All of those seem so possible. 😆
My personal theory of how I see it playing out is Hook and Regina working together to take down GOAT and then they can work either independently or together to take down the CharmingStiltskins and then when it is revealed that GOAT is after Henry and kidnap him the entire family and Hook have to come together. Henry is the only thing that would make them all come together.
