This article contains SPOILERS for Severance Season 2, Episode 10, “Cold Harbor.”
When Season 2 of Severance premiered on Apple TV+ in January, viewers likely didn’t know what they were in store for when it came to the finale. After a gripping sequence of events, Innie Mark S. (Adam Scott) ultimately decides to complete the “Cold Harbor” file to free Gemma (Dichen Lachman) from Lumon. Gemma, while at Lumon, was tasked with going from room to room – each one with a different “innie” persona from having had the severance procedure that separates a person’s brain into “innies” and “outies.”

The final scenes in the 10th episode of Severance’s second season saw Mark S. have to make the ultimate choice. In the end, Mark succeeds in freeing Gemma, who leaves the severed floor and pleads to Mark S. to go outside with her. Afraid that he will cease to exist, Mark S. ultimately chooses to stay inside with Helly R. (Britt Lower), who mysteriously appears in those final moments.

Dichen Lachman talks to CBR about the Severance Season 2 finale, including what Gemma was thinking in the final scene between Mark’s Innie and Helly.
Helly Doesn’t Hesitate in the Finale
“I think it’s just instinct,” Lower said in an interview with The Hollywood Reporter as to why Helly appeared by the doors. “She knows that Mark must be getting close to the exit and just wants to see him one last time. I don’t know. She just goes, she doesn’t hesitate,” Lower said.
She explained that it seemed like Helly was putting everything in Mark’s hands at that moment. “And the way that scene played out, I think, was really giving Mark the choice. She shows up, but she lets him make the choice,” Lower said.

Severance’s Season 3 Fate Revealed by Apple Following Season 2 Finale
Apple TV+ has renewed the hit series Severance for a third season following the debut of the Season 2 finale on the streaming platform.
The Series Creator on Mark’s Change of Heart
Severance creator Dan Erickson said that the moment showed that Innie Mark, who had previously valued his outie’s life more than his own, was starting to see that his life is equally important. “But it just occurred to me because at the very beginning…I mean, literally the first thing that we see innie Mark do (in season two) is come out of the elevator and run to go find Ms. Casey (Gemma’s severed floor innie).”
Erickson continued, “At that point in the story, he still feels totally beholden to his outie and that life, and I think still on some level, sees his outie as more important than himself. And so, what if this season you try to get Mark to the point where he’s standing at that door about to go out and finally give his outie what he’s always wanted – his wife back – and he doesn’t do it because by this point, he has come to value himself as a person and values his life and the lives of his friends and work family as much or more than the outies? That just seemed like a really interesting place, a challenge to try to get his character to that point.”
Seasons 1 and 2 of Severance are streaming on Apple TV+. Season 3 was just given the green light by the streamer.
