Dichen Lachman is just as surprised by that ‘Severance’ plot twist as you

(Warning: This article contains spoilers for “Severance” Season Two.)

Season Two of “Severance” wrapped with a gripping finale that’s left fans buzzing over Mark S.’s decision.

In a stunning twist, Adam Scott’s character chooses to remain on Lumon’s severed floor with Helly R. (Britt Lower), instead of escaping with his beloved wife, Gemma (Dichen Lachman).

What it all means is anyone’s guess. Unfortunately, what becomes of the trio — and answers to the show’s many other lingering questions — will have to wait until Season Three, which has been confirmed, but has yet to receive a release date.

In the meantime, Lachman, who plays the tortured Gemma (or Ms. Casey, if you will), sat down with TODAY.com to talk about innies, the reality of working with Ben Stiller and if she got to interact with the show’s real breakout stars: the goats.

Not knowing the ‘Severance’ plot

According to Lachman, many of the show’s pivotal plot points, including the fact that Gemma’s innie husband, Mark S., was spending his work days tweaking her consciousness, were as much of a surprise to her as they were to fans.

“I didn’t actually know that that was what Mark was doing on the computer until very, very late. I think even after Season One had ended. It had been months and months and months until I had that information,” Lachman tells TODAY.com of the major “Severance” revelation.

Was it a challenge not to know?

“Sometimes it’s challenging, but on this show, I really feel like they’ve always been very open telling me what I needed to know in order to do my job,” Lachman explains, saying that even though parts of the “Severance” plot were kept under wraps, she trusted that it was all part of the process.

“I feel like I’m a big believer in just trusting the universe to some degree,” she adds. “If this is the group of people, this is the way they work, that creates this beautiful magic, then just surrender to it and go with the flow.”

On why she thinks ‘Severance’ is ‘relatable’

While the “Severance” concept of living a completely separate work and home life is pure fiction, the idea of having different versions of ourselves isn’t far-fetched at all.

“I think that so many people relate to having duality and having different parts of themselves that they want to live,” says Lachman.

“It’s that desire when you are in a job that you feel isn’t fulfilling you, or you’re in a relationship that isn’t fulfilling you, parts of yourself start dividing and you want to explore other things, or other things draw your attention. That’s why it’s so relatable,” she explains.

People can have many different facets and interests, including Lachman.

“I definitely have lots of different innies,” she says. “I have the gardener innie, the cook innie, the mom innie, the work innie. I feel like I compartmentalize myself into so many different versions of myself and so many different things give me joy, and I put my 100% focus into that.”

Before working with Ben Stiller, she was a fan

Ben Stiller, star of comedies like “Zoolander” and “Meet the Parents,” serves as executive producer and primary director of “Severance,” and Lachman says working with the Hollywood veteran has been nothing short of “thrilling.”

“There’s this excitement that Ben has when he’s directing,” she says.

She calls Stiller’s passion and dedication to “Severance” inspiring and because of that, “it elevates everyone’s work around him” — including hers.

“His energy makes me want to be better. It makes me want to be the best I can be, the most committed I can be, and just give it everything I’ve got. And I found it one of the highlights of my careers to work with him,” she says.

Even before she worked with Stiller in “Severance,” Lachman says she was a fan.

“‘Reality Bites’ was my favorite movie growing up. I grew up, not in America, and I was just dying to get a Big Gulp from a 7-Eleven. It was like one of those things that I just felt like would make me so cool,” she says of the 1994 movie.

“(Stiller is) legendary, and it is a little bit of a transition to just get over that entertainment deity-like person and then realize you’re actually working together to achieve the same goal,” Lachman explains.

Beyond that? “He’s wonderful at just making you feel comfortable. And as an actor, directing an actor, there’s a level of empathy there that I haven’t experienced before. So I feel just so grateful that I had that opportunity.”

On getting ‘headbutted’ by a goat

Of all the plot twists and head trips on “Severance,” it’s the goats that have arguably sparked the most conversation, making them the show’s biggest breakout celebrities.

When asked if she got the chance to interact with Emile or any of the other “Mammalians Nurturable,” Lachman says despite wanting to pet them, she didn’t have much interaction.

“The others had an opportunity to work with the goats. I, sadly, only got to sort of wave to them from afar, but they’re so cute,” she says.

Perhaps it was for the best because according to the “Severance” actor, her past experience with the animals hasn’t always been great.

“I did once, in a very old movie, get headbutted by a goat. That wasn’t on film, but I have worked with goats before and they can be quite diva-ish.”
