Severance Season 2’s Episode 1 Seemingly Confirms Mark’s MDR Role & Numbers Have Something To Do With Gemma
Season 2 Episode 1’s Ending Hints At What Mark Has Been Working On
A lot happens inSeveranceseason 2’s episode 1. However, the most intriguing moment of the episode is in its final moments when the MDR team finally sits down and starts working on their Marcodata Refinement files. Mark seems to be working on a file called “Cold Harbor.” As soon as he sorts some data on his screen into the bins below, the show briefly switches to another computer screen that shows a picture of Gemma/Ms. Casey with other information. A closer look at the screen reveals Gemma’s heart rate and other vital functions.
When Mark sorts the data on his screen, his file’s progress bar increases to 68%, which is the same number reflected on the progress bar on the screen with Gemma.

The screen that shows Gemma also has “Cold Harbor” written in the top right corner,suggesting that Mark’s work has something to do with her. When Mark sorts the data on his screen, his file’s progress bar increases to 68%, which is the same number reflected on the progress bar on the screen with Gemma. These subtle details fromSeveranceseason 2 episode 1’s ending seem to confirm that Mark’s MDR work is directly linked with his outie’s wife, Gemma, who is believed to be dead.
Severance’s Season 2 Story Development Further Supports Mark & Gemma’s MDR Theory
The Gemma Revelation Makes A Season 1 Theory More Convincing
AfterSeveranceseason 1, many viewers theorized thatthe MDR is performing machine learning by sorting the numbers and data sets. They are unknowingly helping Lumon either train something or manually “edit” certain people or groups to make them more pliable or compliant. It was also theorized that Mark had specifically been working on Gemma’s file, which would explain why, when he was a new employee, he managed to sort all the data in his first file in one go. The MDR employees call it his “freshman fluke,” but his success could have something to do with his familiarity with his file’s data.
Severance’s “Macrodat Uprising” Video & Why MDR Is Considered Heroes At Lumon
Lumon shows a strange “Macrodat Uprising” video to the MDR workers in Severance season 2’s episode 1, raising questions about the company’s motives.
InSeveranceseason 1’s ending, Ms. Casey was also sent to the testing floor after failing to fulfill her responsibilities. She also seems eerily robotic almost throughoutSeveranceseason 1, suggesting she is not a normal human. The “Cold Harbor” file also has a section that says “25.00 (Build),” hinting thatMark is working on Gemma’s 25th iteration. Although the true nature of MDR’s work and Lumon’s purpose remains shrouded inSeverance, these little details hint Mark and the other workers are “refining” or “developing” actual people.
