So its fitting, naturally, that we pick up with Emma (and everyone else) asking WHAT?
when they learn Regina has told her sister to pursue her love with Hades.
Anyway, Hades shows up and asks for help.

He says theres a portal in the cemetery that will open and bring them back to Storybrooke.
And, in the continuing theme of Hades being truthful, there is.
Well, theres a clocktower thats migrated there that will serve as a portal.
Hades does take their names off the tombstones, though, despite Hooks suspicion.
His soul has left his body, which means hes kind of screwed.
Henry doesnt want to leave the Underworld because they havent saved enough people.
Regina is at first wary, but her good soul wins out, and she agrees to help him.
Rumple, meanwhile, is dealing with a pissy father, as Pan wants the heart he was promised.
Rumple shows up and takes Robins heart, because poor Robin just hasnt been through enough lately.
NEXT: Pick me.
In Maine, a 2009-era Emma with adorable black-framed glasses is looking for answers about her family.
Shes also a bounty hunter wanting to take her in for a warrant in Phoenix.
Emma is even better, though.
Before Emma leaves, she makes a purchase: her own armor, a.k.a.
the red leather jacket thats become a staple.
When Reginas power doesnt work to free them, they realize theyve been duped and stopped from leaving.
Meanwhile, Emma and Hook take their elevator ride and find a scale waiting for them.
She does, and ends up falling to the ground in pain while Hook catches fire.
Through the portal they go!
Im still not over the fact they brought a baby to the Underworld.
He sends her up in the elevator and says hes not following because he cant, anyway.
But he knows Emmas love for him is real, and thats what matters.
And man, Emma is upset.
Even more upset than when Hook died the first time.
Heartfelt moments in the Underworld, you guys.
So many of them tonight.
Pan wants to go as well, and he wants his heart, which Rumple gives him.
Pan doesnt deserve happy endings.
And now everyone is back in Storybrooke well, almost everyone.
