I’m inclined to believe Henry was taken to Storybrooke by someone opposing Peter’s plans for him, it can’t be a coincidence that for 11 years Storybrooke was the one place on Earth that Henry could’ve grown up without being found by the Home Office agents.
Possibly, but again that brings up the question of someone else in our world having to know all about these people and the specific situation, and right now we have no one else who would fit that bill. Unless it was someone within THO working undercover to thwart PP’s efforts?
I guess maybe Tink, if she was working against PP instead of being his ally. We just dunno yet what her role will be or if she was even able to come to our world to have been able to interfere with Henry’s whereabouts.
