As for the topic at hand, I like the idea of Elsa being the first openly gay character on the show. The only thing I wouldn’t want is a ONCE twist where Anna was her lover, instead of sister.The beauty of Frozen was the sisterly relationship
Don’t see them changing that, it would be a great and welcomed contrast to the bad sister relationship we just had with Regina and Zelena, and as much as they might like to put their own twist on characters, that would be too much of a twist even for OUaT. No, don’t worry about them making Anna anything else but Elsa’s sister.
