Editor's note: The below interview contains spoilers for Severance Season 2.Apple TV+'s is home to a lot of twists and turns, but perhaps one of the twistiest aspects of all is the possibility of romance that has emerged for certain characters, despite the fact that many of them are literally living severed lives. This season, relationships are becoming even more complicated for innie like Dylan G. () or Mark S. (), but back when the show first premiered, one of its sweetest and, surprisingly, most innocent dynamics was introduced through the romance between innies Irving B. () and Burt G. (), who offered an unexpectedly light contrast to some of the series' darker happenings. Theirs is a relationship that's given even more weight because of the veteran screen presences behind it, but their innies' connection also seems to carry over into Season 2, as Burt finds himself drawn to Irving's outie outside of Lumon — and ultimately extends Irving an invitation for dinner at his house, with his husband Fields () also in attendance.

Ahead of Severance's long-awaited return, Collider had the opportunity to speak with many members of the show's cast, including Walken, about some of their characters' most pivotal moments in Season 2. Over the course of the interview, which you can read below or watch above, Walken reflects on his surprising road to joining Severance, how his longtime friendship with Turturro informed their characters' on-screen romance, and why Irving and Burt are continually drawn to one another. He also discusses his memories of filming Episode 6's tense dinner scene, what it was like playing husbands with Noble, and more.

CHRISTOPHER WALKEN: I've only learned that recently, and I'm very glad to hear it. I’m glad it happened. I think one of the things about Burt and Irving has to do with Chris and John. I've known John for a very long time — 40 or 50 years. We were young actors, going around New York looking for work. I've known him a long time. He's a terrific director, and I've been in two or three of his movies. I know his family. You can tell when you see people together that they've known each other a long time, that they like each other, they laugh at each other's jokes, they finish sentences, and so I think .

WALKEN: When you look at any two people who are together, married or together — what's that song, “Some Enchanted Evening?” — “Who can explain it? Who can tell you why?” It's mysterious.

WALKEN: No. People love each other. Who knows?

WALKEN: For some reason, and I think I know partly what it is, early in my career, I got started playing disturbed people. I played suicidal people, people who got into trouble, and that kind of got a thing going with me where I played all these twisted people. But , especially at this point in my career. So, that was a big plus when it came to playing this part. It was not only with people that I admire a lot, but it was something different for me.

WALKEN: You’ve seen the second season; I haven’t. I've seen the first season, but the second season, of course, I remember shooting the scenes; I know what they're about, but on the other hand, anything I've ever done, you shoot it, and then you go see it a year later, and it's always surprising. There's stuff about it and there’s stuff in it that I hadn't noticed was there. Even when I shot the scene, and I think I know what it was, it's always a surprise.

WALKEN: I don't know where it turned out to be. As I say, I haven't seen it, but when I read it, I thought, One of those Thanksgivings where people start to talk politics or something, and all sorts of stuff comes out that maybe would be best left unsaid. That's how that scene struck me. I don't know what I'm going to think when I see it.

WALKEN: The elephant in the room, yes.

WALKEN: I didn't know him. I'd never met him. I've seen him before. We only shot that for a couple of days, so .
