Did you catch last night’s Winter Finale of Once Upon A Time? It was quite the emotional roller coaster, as Emma Swan struggled her inner battle of good vs. evil, and her main man, Hook, struggled with the same. The episode’s conclusion was ridiculously shocking, even for OUAT, and OUAT l-o-v-e-s to throw us emotional punches. So now, of course, it’s time to talk about it. If you haven’t watched “Swan Song” yet, turn back now, because spoilers are ahead.

With Emma and Hook as co-Dark Ones, one of them had to absorb all the darkness power to rid Storybrooke of ALL the Dark Ones, and in doing so, die. Emma was willing to do it to save her family, but in a last second twist, Hook — finally deciding what kind of man he wants to be — was the one who found himself totally consumed by the darkness. Emma stabbed him with Excalibur, and he died. Like, FOR REAL. There’s no, “is he or isn’t he?” question about it. Hook is dead.

But — of course there’s a but! — there might be a way to save him. You see, before his death Hook summoned all of the Dark Ones to Storybrooke, and they arrived via ferry from the Underworld (would you seriously expect anything less from OUAT?). Emma realizes that even though she’s no longer the Dark One, she’s still tethered to the Dark One’s dagger, and politely (read: pressures) Rumpelstiltskin into summoning the Underworld ferry for her. She’s going to bring Hook back to the land of the living.

Entertainment Weekly caught up with the cast of OUAT to discuss this brand new location, and offered up some hints as to what we’ll see when the show returns. As for the Underworld, it looks like Stroybrooke, but there’s more to it than meets the eye.

“It’s almost identical to Storybrooke,” Lana Parrilla, who plays reformed Evil Queen Regina, explains. “It reminds me of when Marty McFly goes back to his old neighborhood, it’s just different and torn down, there’s graffiti everywhere. Storybrooke doesn’t look the same at all.”

Being in the Underworld also means that those who have died on the show — from Regina’s mother, Cora, to Henry’s great-grandfather Peter Pan — can once again make an appearance in this new twisted-Storybrooke. Ah, so this is why so many familiar faces are returning!

“Everyone has unfinished business,” Parrilla continues. “That’s why all these souls are down there. For a lot of them, we’re that business. And I would say, Regina’s probably most of that, as is Gold. We’re going to be confronted with a lot of angry souls.”

And also Hercules and Megera at some point during the season, since their involvement has already been announced, and that’s zero to hero exciting. For me, though, the most important departed OUAT-er is Neal, and if Peter Pan can show up again, so can Neal. Nothing also says that Emma’s only allowed to rescue one of her great loves from the Underworld.

The thing is, though, we’re going to be waiting a while to see what happens. OUAT is on vacation until March 6th. At least there’s a teaser for the second half of the season available. Check out the preview below, but there’s no way this short :30 seconds is going to last us for the next two months.
