TVLine: Why did Rumple restore magic in Storybrooke?

Question: Probably a stupid question, but in the Once Upon a Time finale, did Rumple restore the magic — even if it meant empowering Regina — because he was so ticked about Belle being hidden away so long? —Joshua
Ausiello: You are correct — that was a stupid question. ”His plan was set in motion long before he knew that Belle was alive,” notes exec producer Adam Horowitz. “ So all his actions in the finale were part of something else going on. When he discovers that Belle is alive and that Regina had her locked away, that’s a wrinkle in his plan and something that he must deal with in Season 2 while he also deals with whatever agenda he already has (hey, we’re not gonna spill that just yet!).”
