Once Upon A Time Season 4
Elizabeth Mitchell guest stars as Snow Queen in Once upon a time Facebook/OnceUponATime

In the previous episode we found out the truth about the Queen's evil plans for Emma, while in flashback we discovered Belle's connection to Anna's disappearance.

The episode revealed that she wanted to replace Anna with Emma. In an interesting twist, another prophecy was revealed which said that the saviour would become Ingrid's sister.

Emma would never join Ingrid willingly, but she had a plan that would get her the family she desired – a magic mirror. The mirror was cast with a spell that could turn everyone in town to turn on each other until the only ones left were Ingrid, Elsa and Emma.
