Matt's Inside Line: Scoop on Once Upon a Time, Castle, New Girl, Gossip Girl, Awkward and More!

Mayor may not “Caskett” have a conflict ahead? What happens when Once Upon a Time and Buffy cross streams? Is Awkward love in the air? Read on for those answers, plus other teases from TV’s hottest shows.

Castle | As you anxiously await the well-teased “Cuffed” fun coming on Monday, here is Stana Katic dishing on the following episode, in which Castle’s good friend, Mayor Weldon himself (now played by Damages‘ Derek Webster), is suspected of murder. “It’s a conflicted case for Beckett,” Katic said. “She knows that the mayor is valuable in keeping Castle in the precinct, but at the same time she doesn’t want anyone who’s committed murder to get away with it. She won’t compromise her sense of right and wrong.” Castle, meanwhile, understandably maintains the mayor’s innocence, creating friction in the squad room. “It’s his friend and he thinks he knows him,” says Katic, “so [Rick and Kate] will stand on two different sides of the line. But the case is a little bit greyer for Beckett than for Castle, and she has to figure out what to do with [the implicating] information.”

Once Upon a Time | Fans of ABC’s fantastical freshman series geeked out more than a little when Emma Caulfield was cast as the Blind Witch from Hansel and Gretel lore. And the show’s bosses share that enthusiasm. “We’ve been huge fans of hers since Buffy, so we’re very excited to have her on the show,” Adam Horowitz told me. Added Edward Kitsis: “We couldn’t think of anyone better to trap two children in a house and try to eat them” than the portrayer of a onetime vengeance demon. Though the EPs were hesitant to share much more about Caufield’s Episode 9 storyline, I’m hearing it will be revealed that the Blind Witch has a none-too-friendly past with the Evil Queen – something having to do with an item that one of the villainesses stole from the other.

Ask Ausiello: Scoop on Once Upon a Time‘s Clumsy New Fairy

Awkward | Dipping into the reader mailbag, Raissa asks: “Any Awkward scoop?” Oh, honey, everything I do is awkward. TVLine recently met up with the MTV charmer’s creator, Lauren Iungerich, and she confirmed that Sadie will for sure get a love interest in Season 2 — namely a fella who is “a lot different than Sadie, although very confident. He has to have enough of a backbone to take her on.” Iungerich typified the romance as “very surprising” and – wait for it – “definitely love.” Awwww…kward.

Matt’s Inside Line: Scoop on the Sons of Anarchy Finale, Supernatural, Homeland, Gossip Girl and More

Gossip Girl | Popping open another reader email, Victoria wonders “if (when?) the Van der Woodsens/Rhodes are ever going to find the truth out about Ivy/Charlie” — a very legit Q seeing as how just this week “Charlie” “admitted” that she was “really” Charlie but was “forced” to pose as “Ivy.” (Whew, I’m out of airquotes.) When I chatted up Kaylee Defer at the 100th episode soiree, she was mum on the timetable for that reveal, but ventured that once the bombshell is dropped, two adults – and not Serena – will be most devastated by the duplicity. “Serena is just so used to people saying that they’re not who they really say they are,” the ingénue noted, “while Lily and Rufus became kind of parents to [Ivy] — so they’ll probably take it the hardest.”

Gossip Girl Spoiler Alert: 8 Things You Need to Know About Blair’s Wedding Day

New Girl | If you think that quirky Justin Long represents the sort of “interesting” men Jess will date, think again. In fact, right now the Fox hit is casting the guest-starring role of a completely and painfully uninteresting fella Jess will hook up with on, of all occasions, Valentine’s Day. Adding to the awkward: This guy still lives with his ex, which makes for less-than-heavy petting on the sofa. Nick’s “date” for the night, meanwhile, is also a dude – an intern who works for his soon-to-be girlfriend Julia (played by Party Downer Lizzy Caplan).

Burn Notice Scoop: Dean Cain, Eric Roberts, Kristanna Loken Booked For Red-Hot Finale

Burn Notice | I cued up the Season 5 finale (airing Dec. 15) this morning, and it’s got Michael, Fi and the gang jumping through allll kinds of hoops, largely because of a big reveal that’s uncorked at the close of the preceding episode. The good news is that the good guys find evidence that links Anson to the explosion/deaths he’s been threatening to pin on Fi; the bad news is that said “smoking gun” might not be around long enough to prevent Fi from turning herself in. Why now, more than before, is Ms. Glenanne compelled to “confess”? Let’s just say that Anson is going to ask Michael to do the unthinkable.
