Lana Parrilla even said that, Adam and Eddy are really setting up a sisterly relationship between Emma and Regina, which would parallel the Elsa and Anna sisterhood. I know…just another weird connection because Regina is really Emma’s Grandmother through marriage….but a type of sisterhood is where they’re heading for.
Well if your step-grandmother were frozen at the same age you currently are, you might become like sisters. However, that raises the question of why Emma and Snow aren’t closer and more sisterly. I get that Emma feels more similar to Regina since they both have magic and that they’re both mothers to Henry. Yet, I would hope Emma could have a closer relationship to Snow the way she and Mary Margaret were close in S1, before Emma realized she was indeed her mom. Why is it that Emma can forgive Regina for casting the dark curse which caused her to grow up an orphan in this world, yet Emma doesn’t seem able emotionally to open up to Snow, who only sent her away to give her her best chance? I wish Emma could give her own mom more of a break. Emma is also a lot closer now to David than she is to Snow.
