I’m a huge fan of Elsa, so to see her meet Emma was truly enchanting. I think the only other time we’ve ever seen Emma really bond with a female friend was with Mary Margaret in season 1, before she found out she was really her mother. So it’s nice to see Emma and Elsa become friends. I think Elsa is lonesome for Anna, so she probably welcomes having a friend and sister figure in this strange and foreign land. I know it probably won’t last beyond the first half of season 4, but it’s nice while it lasts.
