Honestly? I have no idea. But this is what is happening in my head right now. Rumple is just sick and tired of all these fools. All of them. Snow, Charming, Regina, Random Guy on the Streeth #21346. Doesn’t matter. He wants out of the nut house that is SB because who the frack wouldnt?
Also I would say…The rest of the world is probably a MUCH safer place to live in then Storybrooke. I mean come on every week a new crisis or Villain, or something happens.
