Well i meant before the Dark Curse. If Rumpel’s goal was to kill Regina then he should have just killed her. But even now he could kill her non magically. That works just as good. Dead would still be dead. It just seems like Rumpel is less likely to play with people before he kills them then the queen is. The queen seems to like to ruin people first. Destroy their lives.
I think that there will be a trial of some sort, but it does beg the question of where would Mary be in jail if she was convicted. She would be sent to some sort of state facility in real life. She is going to get off.
