This curse can’t have been that much fun for Regina either- she has been stuck there for 28 years in limbo without her magic! Her only good deal is that she is in a position of power and gets to watch the others suffer. But obviously, this has not brought her true happiness….she adopted Henry in an attempt to fill the void. I suppose she may have an idea who Emma is, but she hasn’t indicated it. She has only shown she has issues with Henry interacting with a stranger she doesn’t trust. Does she realize that Henry is Snow White’s grandson? Would that bother her or would she just think of that as another way she has taken something from Snow White.
