Severance's Dichen Lachman Explains the Shocking Meaning Behind 'You'll Kill Them All' in Season 2 Finale 😱

Ever since watching Severance’s Season 2 finale, I can’t stop thinking about the line “You’ll kill them all.” It’s screamed by Dr. Mauer at Gemma and Mark as they’re about to leave in an elevator, and while I have my assumptions about what it means, I needed to know more. Thankfully, CinemaBlend had the chance to ask Gemma actress Dichen Lachman about it, and her explanation of this quote’s meaning will haunt me until Severance Season 3.<br /><br />In the final episode of Severance to air on the 2025 TV schedule, we finally saw Gemma escape that hellish testing floor with Mark. During the season, we learned that Lumon was trying to tamper with her emotions with various rooms that contained her biggest fears or things she loathed. This required her to be severed well over 20 times.
