Have you seen the script tease where Emma and Snow are discussing the engagement? The dialogue feels very carefully constructed... like they're trying to emphasize Snow's expectations for Emma's love life! Immediately made me think of your multiverse theory
Yes! I had the same thought right away. It’s like they really want to draw our attention to how this is about Snow. It already started when she was still Mary Margaret and suggesting that Emma was in love with Graham, while Emma made it incredibly clear she wasn’t interested when she was… actually interacting with Graham. They’ve been supporting it in subtext. Like before the ball, when Emma was dressed in white, she looked so sad and uncomfortable and Snow was oblivious to it while she went on about having dreams to take her daughter for her first ball. That scene breaks my heart, cause they both want to make up for lost time in their own way.
