Severance: Graner’s death and its impact

Severance reveals Graner’s final moments after Cobel orders him to take care of Reghabi. It is unclear if he follows Mark to his secret meeting with Doctor Reghabi or if he reaches there not knowing Mark would be there. It is probably the latter. Reghabi is the woman who once tried to reintegrate Petey. And she is the one who wants to help Mark understand what Lumon is doing.
Graner shows up but before he can do anything, Reghabi attacks him from behind. She kills him with a heavy bat. She then takes his security card, which becomes the most important thing she hands to Mark.
Severance uses this moment to show how one death can open doors quite literally. Graner’s card helps the innies move into areas that were completely closed off before. They learn more about the other departments, the layout of the halls, and the power Lumon keeps over every floor.
The card becomes the key to all the discoveries that happen. At the same time, Mark is forced into a new emotional space because he realizes he is now tied to something violent. Even though he never touched Graner.
Severance also uses Graner’s death to show how quickly Lumon can clean up its problems. There is no police investigation that affects the company. There is no public story, and there is no fallout that reaches the outside world. It almost feels like Graner vanished, which tells the audience how powerful Lumon really is. Viewers have pointed out that the scene proves the company can control any situation.
Graner’s fate also shows how the world outside Lumon is just as dangerous as the world inside. His death becomes proof that people like Reghabi are willing to go to extreme levels to expose what the company is doing. It tells the audience that the fight against Lumon is not clean or simple. It is messy, risky, and full of choices that scare even the characters who want the truth.
