I could see Regina dying, but not likely until the end of the show’s run. They’re not gonna alienate all the EvilRegals before the whole series is complete, that’d just be a stupid business move to piss off such a huge chunk of your audience. But it would be kind of poetic, that when the show began, we saw her sacrificing her father’s life to make all this happen, and then in the end, she somehow sacrifices herself to make it all right again.
