Spoiler Room: Scoop on Once Upon a Time, Arrow, Supergirl, and more

Arrow type TV Show network The CW genre Superhero

Welcome to the Spoiler Room, a safe place for spoiler addicts to come on a weekly basis to learn what’s coming next on their favorite shows and, hopefully, get a few of their own questions answered. If you want scoop on a specific show, send your questions to spoilerroom@ew.com.

What can you tease about Once Upon a Time? — Harley

There’s an upcoming flashback that offers up what’s sure to be the most heartbreaking piece of information this show has dealt with throughout the entire series. Can’t say more than that, but you may find a hint in this week’s Hot Seat.

If Chase is Prometheus, then who is under that Vigilante mask on Arrow? — Maggie

Alas, we won’t find out soon. “We know the answer to that,” executive producer Marc Guggenheim says. “You probably will not get the answer to that in season 5.”

What can you reveal about Alex in next week’s Supergirl? — Charlie

Well, she’s going to some dark places in the wake of learning her father is colluding with Cadmus. “It’s hard because when they realize that there’s a deeper issue going on with Jeremiah, you don’t really know where his loyalties lie,” Chyler Leigh says. “When that’s questioned and Alex gets put in a position where she’s questioning it, it becomes this deep, dark intense realizing, her coming to grips with the fact that this isn’t in her control. Basically, Alex goes head-to-head with Lillian Luthor, so it’s a really powerful episode.”

Anything on the Vampire Diaries finale? — Marie

There’s no better place for nostalgia than a series finale, and this one is going to be packed full of it — so much so that you’ll even recognize a line or two. “Remember when Damon was dangling Vicki over the building and he says, ‘For me to know and you to dot dot dot.’ Spoiler alert: You hear that line in the finale,” executive producer Kevin Williamson says. “There’s little Easter eggs like that throughout the whole thing.” So which lines do you hope to hear again?

We know the Jennings’ are doing better this season on The Americans as a married couple and that Paige is in a relationship with Matthew Beeman, but what about Henry? — Lou

I’m so glad you asked about Henry, the consistently forgotten Jennings child! Without spoiling too much, this season just might be the best one yet for Henry fans. “Henry is in a very interesting position this year,” writer-producer Peter Ackerman says. “He’s the odd man out in his family, whether he knows it or not, and he’s teetering on a certain point… He has the potential to go different directions, and I’m intrigued by how he stakes his claim this season.” Adds creator and executive producer Joe Weisberg: “It’s kind of a breakout season for him.” Better that than breaking into his neighbor’s house, as he once did in season 4.

Did all those Daisys die in the HQ explosion on Agents of S.H.I.E.L.D.? — Martin

That remains to be seen, but I have a hard time believing Fitz would mention enabling the “seek and destroy mode” just prior to the explosion and not getting resolution there. “When we come back, we’ll see how big of an explosion it really was,” EP Jed Whedon says. However, he hedges: “The idea was May sacrifices herself to try to put an end to what they’re doing.” So maybe don’t hold your breath?

Any Malec sccop for the Shadowhunters finale? — Sky

Considering that Valentine has the Soul Sword, there’s one thing I can guarantee: Magnus, along with the rest of the DownWorlders, is in danger — and if anything forces couples to re-evaluate their relationship, it’s a life-or-death situation. I can’t say what it is, but expect Malec to make a big decision by the hour’s end.

How did Red have so much info on Tom on The Blacklist? Is he connected to Christopher Hargrave’s disappearance? — Kyle

Just because Red knew Tom was Scottie’s son does not mean he played a role in the abduction. In fact, the writers are trying to keep the mythos of each show somewhat separate. “What Reddington told Tom was to stay away from it,” EP Jon Bokenkamp says. “There’s no good that is going to come from [him] going into this world and asking these questions. Red is not somebody who has a tremendous amount of love for Tom. They’ve had their own fraught relationship, but that did seem genuine. That was one of the most caring things Reddington’s ever told Tom, and he probably said that because he cares about Elizabeth and Agnes. But as far as the history, the two shows share some DNA, because they live in the same landscape, and there’s great potential for some crossovers, but I don’t think Red had anything to do with the origin of this story. Of course, he’s always full of secrets, so who knows? But it feels like it stands on its own.”

Will the Mahoneys return next season on How to Get Away with Murder? — Brenda

Survey says: It’s likely. “I don’t think we’ve closed the Mahoney chapter completely, but I also don’t know if it’s going to be that dominant of a storyline next year,” EP Pete Nowalk tells me. “Obviously there’s a lot of baggage between Sylvia and Annalise, so it depends whether Annalise is going to dive back in there or not.”

Time After Time comes out this Sunday. I’m a fan of time-travel shows — anything you can tease about this one in advance? — Barry

I can tease that Time After Time won’t stay in the present once H.G. Wells catches up with his best friend John Stevenson, a.k.a. Jack the Ripper. This time-travel show won’t hop to other historical periods every episode, but it will be going to Paris during World War I and even stopping by the 1980s. So stay tuned! H.G.’s time machine gets put to good use.

This week in TV: The casting so far on Marvel’s Inhumans has me beyond excited.
