I think that it’s reasonable, given that Rumple found Ursula outside of Storybrooke, to believe that The Dragon will come back into play somehow. He was the first hint we had that magic had crept into The Land Without Magic beyond Storybrooke’s invasion. All we really know about him though is that he had magic and a link to another realm somehow…and that he knew who August was.
But with Ursula in this realm outside of Storybrooke, there’s good reason to think that SOMETHING is going on. The Home Office front that Pan was using to find Henry did seem to be sussing out magic in other places…it would be kinda cool if they connect all these dots they’ve laid out.
I don’t completely trust A&E to do that…but sometimes they do lovely things like that.
