Honestly, we had the whole Evil vs Wicked thing between Regina and Zelena just this Spring, so having a focus be Regina vs Elsa would have been redundant. Yes Regina has the most vocal fanbase within the fandom, but she’s not the only character on this show. So Elsa and Emma interacting is something I am totally all for.
I know….but they make it sound like Emma is the only character Elsa could really relate to, and once you list the things they have in common, you only come up with two or three, whereas with Regina or even Rumple…you can come up with about five or more! And I did not say an Elsa vs Regina…I mean a more friendlier, future Best friends forever type of relationship with Regina and Elsa. The Queens have to stick together!
