Question: Any NCIS: LA scoop? —Kria
Ausiello: The May 14 finale will be a veritable Big Badapalooza. “It’s like a supervillains episode,” teases Barrett Foa. “Basically, every bad guy we’ve ever done battle with [is] coming back for the finale.” The returning evildoers include traitorous CIA vet Isaak Sidorov (played by Sons of Anarchy‘s  Timothy V. Murphy) and “The Chameleon” (Highlander‘s Christopher Lambert). “Big nuclear things are going down,” the actor adds. “It leaves you on the edge of your seat [and] is, of course, a great cliffhanger.”

Question: How worried should we be about Mer’s baby on Grey’s Anatomy? —Jennifer
Ausiello: Not nearly as worried as you should be about the person delivering Mer’s baby on Grey’s Anatomy. (In other alarming finale news, did you hear about this?)

Question: Wanted to ask you whether you’ll be sharing any clues/hints/updates on this blind item anytime soon. —Rida
Ausiello: Turns out a lot has changed in the four months since that item was originally posted. Basically, what was initially conceived as a separation has now allegedly-possibly-maybe evolved into a drastically different 10-letter word.

Question: Today is my birthday—the best present ever would be some juicy Scandal scoop. —Miranda
Ausiello: How about exclusive details on John Barrowman’s mysterious May 9 guest stint, directly from the actor himself? “I can say absolutely nothing,” the Arrow baddie maintains of his appearance. “All I can say is I’m in Scandal. It is so top-secret.” Curses. Um… how about some behind-the-scenes intel, JB? “It was some of the hardest stuff I’ve ever done,” Barrowman confesses. “I realized again how frightening some things were to do. I was very nervous, but thank god everyone was on my side because I had a very difficult time getting through that day.” A major factor contributing to his fragile emotional state was exhaustion. Recalling his first day on the Scandal set, “I finished filming Arrow at 1 am, went to the [Vancouver] airport for a 4 am check-in, got on a flight [to Los Angeles] at 6 am, got to the set of Scandal at 9 am and started shooting at 11:30 am. I was completely stressed out and tired.”

Question: Will Tommy discover his father’s Dark Archer identity on Arrow before the season ends? —Jacob
Ausiello: Barrowman was a skosh more forthcoming about that. “He’s desperate to tell Tommy,” shares the actor. “But anytime he goes to do it, something happens. We already had one of those moments when Malcolm was almost assassinated in his office. But I’m sure there will be others.” Speaking of the finale, Annie Ilonzeh (Charlie’s Angels) is confirmed to return in the May 15 season ender, as Laurel’s colleague Joanna. “We’re very excited to have her back,” says EP Andrew Kreisberg. “She’s a big part of the Arrow family.”

smashQuestion: With Smash‘s Jimmy getting into a fist fight with his drug-dealer brother at the Bombshell premiere party — and Karen finally calling off their affair because dude is totes scary — does that finally clear the way for the Karen-Derek romance for which we’ve been patiently waiting almost two seasons? –Elijah
Ausiello: Showrunner Josh Safran remains cryptic on the future of “Cartwills,” but he does offer this tantalizing tidbit: “Karen and Derek’s relationship takes a major turn” in the May 4 installment. Before that happens, though, it sounds like the two men not exactly in Karen’s life (yep, Derek and Jimmy) are set to clash as early as this Saturday’s episode, building to “a final confrontation — one from which there might be no turning back,” adds Safran.

Question: Do you have any intel on which Smash musical, Bombshell or Hit List, is going to ultimately land the big statuette? Please help — I really want to win my Tonys party pool for a change! –Blanche
Ausiello: You do realize Bombshell and Hit List exist only in Smash‘s fictitious version of Broadway, right? (Although as we speak, Phillip Spaeth, who played dashing chorus boy Dennis in Season 1, is actually starring in Matlida on the Great White Way.) Anyhow…back to the subject at hand: Hasn’t anyone ever told Derek and Scott that you don’t count your Tonys before you’ve actually managed to book an actual Broadway theater? Safran teases that Broadway aspirations for the buzzy downtown musical will “hit a snag” during Saturday’s episode. What’s more, he adds, “a figure from Derek’s past causes a bunch of trouble in his — and many other people’s — present,” starting in Episode 15.

Question: Supernatural, please. —Sandi
Ausiello: Felicia Day is back as hacker extraordinaire Charlie this Wednesday, but the latest visit from the Queen of Moondoor will be a little different. “We’re going to get a pretty special look into her past in a way that we haven’t seen before,” previews EP Jeremy Carver. “We’re going to start to peel back Charlie a bit more. It’s pretty exciting — and moving as well.” Also exciting: Dean teaches Charlie how to be a hunter, and she takes to the life “in a characteristically Charlie way, which would be excited, a bit blustering, then eventually getting the hang of it..”

Question: Any scoop on Max (Josh Zuckerman) returning for the series finale of 90210? Please say he’ll be back! —Jessica
Ausiello: I would if I could but I can’t. Because he won’t.

Question: I’ll take any Once Upon a Time scoop you can share. —Estée
Ausiello: The prospective spin-off, Once Upon a Time in Wonderland, will be — no surprise — “a little more Wonderland-y” than original flavor Once, per consulting producer Jane Espenson. The offshoot, envisioned as an American Horror Story-style 13-episode standalone that would ostensibly bridge the original series’ winter hiatus, will also be “more adventurous” and boast “a lot of humor [and] a lot of spectacle. It’s really going to be gorgeous.”
