Rumplestiltskin declines Ursula's offer to join them, to get villains their happy endings, claiming he will always win. In the present, Gold learns that Ingrid's lingering magic will keep those who leave Storybrooke from ever returning, so he has Hook help him uncover a portal in the Sorcerer's mansion, where Elsa and Anna depart.

Only Henry is left behind, who tracks down Isaac in the Land without Magic, as he discovers that Isaac has become a best-selling author. When Isaac refuses to undo everything (and since he no longer is the Author, having violated the Author's Code), Henry uses a key that sends him and Isaac into the alternate Enchanted Forest. There, in order to undo Isaac's work, Henry has to convince a "Snow White" version of Regina to stop Robin Hood from marrying Zelena, while trying to rescue Emma, who is held captive in the tower by an "Evil Queen" version of Snow White. Henry and Hook help Emma escape the tower and must race against time to make sure that Robin doesn't marry Zelena.

However, Isaac blackmails Rumplestiltskin into stopping Emma, but Regina would sacrifice herself after Rumplestiltskin killed her. Emma shows Isaac what he had done in this world but since Isaac cannot undo what happened, it's Henry who can change everything as Isaac has lost the ability to write, and Henry has become the new Author. Henry uses the ink to undo everything that Isaac did, and the timeline is restored with everybody returning to Storybrooke. The Apprentice offers Henry a chance to become the Author, but he turns it down, snapping the pen. The Apprentice also frees an unconscious Gold from the Darkness in his heart, which had nearly killed his heart, by sending it into the Sorcerer's Hat.

This purifies Gold's heart and severs his link to the Dagger of Kris in the process. However, the Darkness is too powerful for the hat to contain, and it escapes, attacking the Apprentice. Emma is able to drive out the Darkness with her light magic, but the Apprentice has been fatally wounded, and warns them that only Merlin, the Sorcerer, can prevent the Darkness from destroying all of the realms. The Darkness eventually reappears and attacks Regina, but Emma sacrifices herself and volunteers to tether her soul to the Darkness, to prevent it from destroying everything and everyone, leaving only the Dagger behind, now featuring a new inscription, "Emma Swan."
