Written by the show's creators, Edward Kitsis and Adam Horowitz, and directed by Ralph Hemecker, it premiered on ABC in the United States on May 18, 2018.

In the episode, the Wish Realm Rumplestiltskin's plan to eliminate all the happy endings of all the characters in every realm is revealed, as Sir Henry prepares to kill Regina as part of the scheme, while Alice and Robin seek out help from Storybrooke to rescue Henry, Jacinda, Lucy, Hook, and Weaver, who is ready to risk everything to stop his evil counterpart from carrying out his plan.

They explain that a fifth Dark Curse took them, along with the future versions of Henry, Regina and Mr. Gold to Seattle in the past, which is in the present day.

However, due to the numerous outsiders in the past that has caused Storybrooke trouble, they are met with disbelief and hostility.

He shows Sir Henry that if he raises his emotions, he can banish the heroes into the “Once Upon a Time” books that will serve as their prison.

As they come up with a plan, Wish Rumple shows up, ready to trap the characters in realms of eternal torment, while Sir Henry shows up in the forest to confront Regina and forces her into a sword fight, which causes the portals to open, powered by Sir Henry’s emotions.

When Sir Henry corners Regina, she tells him that if she needs to die to show him that he's loved, it's a worthy end for her story.

After Regina gives her speech with unanimous cheers as Emma, Hook, and Hope look on in support, the camera zooms out of the castle and moves toward Storybrooke, where it shows the different parts of the town including Granny's Diner, Gold's shop, stores along the main street, and the clock tower.

As the series comes to an end, the camera soon shows a shot of the town line, where it zooms in on the "Leaving Storybrooke" sign.

[1] Justin Kirkland of Entertainment Weekly gave the episode a B−, noting: "Gather your tissues, kids, because this is the last chapter of Once Upon a Time.

This show has been such a weird little nugget of television that dared to try to reinvent all the classic fairy tales we grew up reading and put them into a modern, albeit at times messy, new narrative.
