I just don’t see Henry doing magic, except as a means to control his actions while asleep. He already refused magic when Regina offered to teach him, and I think he’s too smart to be tricked. No one hated the curse more than he did for enacting such evilness as revenge against his birth family. He knows better than anyone that magic always comes with a price.
I think Mr. Gold has good intentions when it comes to Henry. He said that Henry shouldn’t have to pay the price for Regina’s use of dark magic, which is what his own son, Baelfire, did for Mr. Gold’s decision to cling to dark magic. Gold doesn’t want what happened to Bae to happen to a good kid like Henry, especially since Henry probably reminds him a lot of Bae. I also believe that by showing Mr. Gold’s tenderness for Henry, the writers are setting the stage to reveal Henry as his grandson.
