Five years later, Anna and Elsa prepare for Anna's wedding to Kristoff when Elsa finds her mother's diary, which reveals that the reason for their "business" trip had to do with Elsa's seemingly uncontrollable ice powers. Elsa feels guilty that she may be the reason for their deaths, but Anna sets out to prove it wasn't, and meets with Grand Pabbie, the Troll King, to find out where their parents had gone. He reveals that they were headed to a land called Misthaven.
Later, Anna goes missing and Elsa seeks out Kristoff to help find her. He reveals that she has set out to Misthaven in an effort to cure Elsa of her powers. Kristoff reveals that there is another name for Misthaven: the Enchanted Forest.
Emma Swan leaves the diner to apologize to Regina for breaking up her and Robin Hood — whom she inadvertently reunited with his deceased wife Marian after travelling back in time.

Regina later makes her way to the mental hospital and releases Sidney Glass, who she has kept there since the first curse broke. She tasks him to help her turn back time to kill Marian.

- Elsa's iconic dress is very different than the dress seen in "There's No Place Like Home", which picks up where that episode left off on. In the previous episode, the hue was darker with gold-colored decorations and the cap was of the same hue and similar to Snow White's in the 1937 Disney film.
