Can you give us any scoop on The Mentalist? –Shena
Will this exclusive sneak peek from this Sunday’s winter premiere (CBS! 10/9c!) fill the bill? (In the episode, Rigsby and Van Pelt must convince J.J. LaRoche to help them investigate who is stalking former CBI members.)

There is a rumor on Twitter that Bones will have another undercover episode, probably with Tony and Roxy. Is it true? —@Katiarabreu
It’s false, actually. Having said that, exec producer Stephen Nathan reveals that Booth and Brennan “will be going someplace they have never been before — the world of female impersonators.” But as the boss man stresses, “It’s not an undercover episode,” so don’t expect to see David Boreanaz donning a wig and fishnets.

I’m dying to know more about Nestor Carbonell’s appearance on Person of Interest! Will we get any “Ben”/”Richard” scenes? –Karen
EP Jonah Nolan told me he’d been biding his time, hoping to grab Carbonell – with whom he worked on The Dark Knight Rises – and the role he wound up with sounds like a doozy. “He represents the first real serious challenge to Shaw — not in terms of a physical threat, but… she gets a little knock-kneed and tongue-tied around the guy.” Alas, Nolan reports, Carbonell’s appearance won’t afford him any scenes with fellow Lost alum Michael Emerson.

Is it possible for someone to find out why there have only been two sightings of Kate Beckett’s engagement ring on Castle this season? –Dan
I am your someone, Dan. And this someone hand-delivered your Q to Stana Katic. “The important thing to remember is that Beckett is a detective, so she can’t wear things that will identify her, she can’t wear things like that on her hands that would distract from the conversation, that could be stolen, that could possibly hinder her when she’s shooting or hand-fighting,” she explained. Also, Katic said, the ring “is something that Beckett’s very protective of, because she loves it, so on occasion, if it’s like a big event or maybe a private moment outside of being in bed, she can wear it. But having it on display at the work place is not appropriate, especially as a detective.”

This week’s episode of Castle was great, I don’t think they’ll be able to top that this season. What should we expect in the next episodes? –Cami
As you may have read, Eureka‘s Salli Richardson-Whitfield will guest-star in Episode 19, “The Greater Good,” as Captain Gates’ estranged, U.S. Attorney sister. Up after that is the already buzzy “That ’70s Show” episode, in which character actor Jon Polito (Millers Crossing, Barton Fink) will play Harold Leone, the onetime consigliere to an infamous mobster who disappeared in 1978.

IMDb lists Ruben Santiago-Hudson in the credits for Castle Episode 18. Any truth to that? –Jenn
None — though bringing Capt. Montgomery back would be a neat trick, amiright?

Any news (good or bad), on my newest ship, Brooklyn Nine-Nine‘s Jake and Amy? ~Lydia
This certainly falls under one of those two categories: I can report that we have not seen the last of Teddy (played by guest star Kyle Bornheimer), with whom Amy just reconnected – much to Jake’s disappointment.

When is Matthew Goode appearing on The Good Wife? –Kevin
Goode debuts as State’s Attorney prosecutor Finn in the March 23 episode — an hour that also marks the return of Hunter Parrish’s imprisoned character, Jeffery Grant. And that’s not a coincidence. “He is the prosecutor of [Jeffery],” exec producer Robert King reveals. “He’s an excellent prosecutor, and has fun in court.”

Any Good Wife info? –Steph
A case in Episode 20 will involve a Libertarian grad student who’s got cerebral palsy and a medical marijuana card. (I know, you’re all, “Ugh, another case involving a Libertarian grad student who’s got cerebral palsy Arrow Harley Quinnand a medical marijuana card?!”)

I’m a huge Arrow fan and I was wondering if you had any hints about the mysterious girl (with the pigtails) in the “Suicide Squad” promo? –Celeste
The CW has no official comment — and I’m hearing it’s possible this mystery woman won’t appear in the actual episode — but our good friends at IGN are speculating that it’s a veiled nod to Harley Quinn.

I would love some scoop about what’s ahead on Revolution. –Stacie
Casting is underway for the season-ending, double-episode role of a blue-collar dad to two teenage kids who “wants to do the right thing for his family at all costs.” Wow, go ahead and order a red shirt for him now, why don’t you?

Will Vikings‘ Lagertha and Ragnar get back together romantically? –Sue
Certainly not anytime soon. As you’ll see after tonight’s four-year time jump, Rags (I call him Rags) is busy doting on the once-again pregnant Aslaug. And when Lagertha next appears, she’s heavily involved with a powerful new fella, in a relationship that is… well, complicated.
