What if Elsa and Anna's mother had a sister, who is the Snow Queen. So just as Elsa is a sister to Anna, the Snow Queen is a sister to Elsa and Anna's mother. However in the past, something terrible happened so the Snow Queen fled to the Enchanted Forest, which is why she developed the persona of the evil Snow Queen. The reason why Elsa's parents might be going to the EA is to find the Snow Queen and try to get her to return and teach Elsa how to control her powers.
