@Heather about your theory, the thing with MC happened during the Christmas break, back then the script of 315 was already with the cast, so cannot be anything related to that, however the MC could have happened bc him knew that MRJ was written of the show, and somehow, that ship discussion( Mc said that they spoke about ships and like SQ was the worst of them) can in BTS on the show, maybe that neal was gone to make CS happen, and MC simply tired of all that crap of ships, that made his friend being written off, simply losts it. Also find it very ood that Keegan was only used for the cemetery scene and will be on 322( i bet in a fb about sending baby emma through the portal), maybe she also said something about what they were doing to MRJ.
Also, i thought about what the fans wanted to see and never knew, i wonder and since a pic of a tree was show, could it be that this thing was , what would be emma life if she was raise by snow in our world( that was the original plan, snow entering the wardrobe bf emma was born, but again this would change a lot, unless snow had a spell that allowed her to not age.
