And now I’m really confused about this scene. It’s night time when she pushed Cora through the mirror and then the next FTL scene is day and Regina is leaving because “that was always the plan” she tells Rumple. If she had just married the King and then pushed Cora through the mirror it wouldn’t make any sense for her to wait until morning given that Leopold would want to consummate the marriage BUT if she was about to marry the king and pushed Cora through the mirror before the wedding, it still wouldn’t make any sense because she was always planning on leaving once Cora was gone so why stay and marry the king.
The line “the kingdom will be yours” does seem to indicate that the marriage hadn’t happened yet except when you take it in conjunction with the preceding line “the king is not a strong man” which I think we are supposed to. Cora is telling Regina that because the king is not strong therefore Regina will be the true ruler of the land. I don’t know if it has anything to do with a time reference. But why on earth would Regina have stayed and married the King if Cora is gone and her plan was to leave.
So either there is a flaw in the writing or we’re missing something.
