Stana Katic: Castle and Beckett’s Sex is ‘phenomenal’

We didn’t think we could possibly be more excited about “Castle’s” Season 5 premiere on Monday (Sept. 24)…and then we talked with Stana Katic.

In case you missed the memo, Beckett and Castle (Nathan Fillion) are a full-on couple following their passionate hookup.

So naturally, our first question to Stana was, “How’s the sex?”

“Phenomenal!” she replied. “Could not be any less than phenomenal.”

“There’s so many different kind of layers to lovers,” she adds. (Anyone else get goosebumps when “Castle and Beckett” are described as “lovers”?)

“I think these two really enjoy each other, and enjoy exploring each other, both physically and intellectually. So I think what’s going to be exciting for the new season is that we’re going to get really cheeky.”

Don’t expect any PDA just yet though. “The NYPD has a strict policy about coworkers dating — they don’t allow it,” notes Stana. “So Castle and Beckett are forced to keep it quiet because they risk losing the working relationship. They’re obviously a powerful crimefighting duo and aren’t willing to compromise that. They have to be lovers [!!!] on the sly and keep it quiet for a while.”

Or try to, anyway.

“It’s difficult to keep a secret like that in a room full of detectives,” admits Stana. “So that adds to the complication — sometimes a subtle glance or a telling word is said in the precinct that could threaten to blow the whole thing up.”

Stana starts laughing just thinking about certain scenes. “So you see these two characters facing that and also confronting each other about missteps they have along the way,” she says. “Which is great fun — it’s really a joy to play.”

Castle and Beckett “are getting to know each other in a different way,” Stana notes. “They’ve been good friends obviously for a few years now and wonderful coworkers and at this point they’re lovers. That opens up a whole different bag of worms.”

Like, for instance, Castle’s two divorces. “I think what we’ll discover is perhaps what happened to those failed marriages,” she teases, finally asking, “And how dedicated can he be to a relationship that means more than a one-night stand?”

What do you expect to see from Castle and Beckett as lovers? Don’t forget (as if) to tune in to the Season 5 premiere, Monday, Sept. 24 at 10 p.m. on ABC.
