[WARNING: Mild spoilers ahead.] Yes, tonight’s episode of Castle is everything it’s been touted to be: a high-stakes race to save New York City from extreme devastation. It’s a nail-biter unlike anything we’ve seen on the show up to this point, but it’s also, at its heart, an episode of Castle. And guest star Adrian Pasdar, who joins the series for two episodes as Homeland Security agent Mark Fallon, told EW that it was that fact — not getting a chance to play a sharp, tough-talking agent — that was most satisfying of all.
“It was such great privilege to be part of the show in many ways, but [the storyline] did service the overall arc of what the show Castle is meant to be. And I think that’s a great thing,” he said.
In the episode, Castle and Beckett need all the help they can get as they race to recover a radioactive bomb. Agent Fallon tries to be that help, but soon finds himself at odds with the twosome.
“It’s one of those situations where I think [Fallon is] a very definitive element that unites Nathan and Stana in a way that possibly other [episodes] haven’t because they’ve been able to retire to their respective corners whenever they needed to emotionally,” he said.
So while this is certainly no “kiss” episode for the Castle/Beckett relationship, Pasdar sees it as a large step on a deeper level.
“[Fallon] forces them into the same corner, and they get to experience what that’s like to need each other and rely on each other.”
The Castle two-part event starts tonight at 10PM ET on ABC.
