I had an amazing epiphany this morning about Captain Swan. This theory involves the potion and Hook’s ship. Since we know that there is an episode coming up called, I think what happened is that Hook traded his ship for the memory potion. He let go of his old new home to return to his new home, Emma.
And it falls in line perfectly with Prince Charming:
And if he would have taken the easy way out and just pretended to be King George’s son, would have lived an easier life but he fell in love and he gave all that up for Snow.
So yeah, I can totally see Hook willing to make this exchange — for Emma because he can’t be without her.
