Episode 2: Why don't Mary Margaret and Emma just tell Mulan and co who they are... Snow White and the 'saviour'?

im wondering the same thing

maybe they didnt recognize her with the short hair lol either that or they have never met snow before. only heard of her. also in answer to your question, maybe they thought mulan and the others were enemies judging by when snow kicked aurora which btw i kinda honestly liked lol judging by the preview for the next episode, it looks like they eventually work together so maybe by the next episode, mulan and aurora will find out who snow and emma truly are.

Maybe they did that just for kicks and clear it up somehow during next week's ep.
