One of the most intriguing parts of Severance is how uncanny the severed floor of Lumon Industries is. The finger traps, the sad parties, and the formal language all feel like — and, essentially, are — a simulation of office life. But defining just what the work these employees actually did was almost impossible. Viewers knew they instinctively sorted numbers, but there’s no clue as to why or what categories the sorted numbers belonged to.
It’s a small part of the bigger Severance mystery, but the Season 2 premiere revealed how these numbers could be the key to what Lumon is doing entirely — and to why Mark’s seemingly dead wife is alive as Ms. Casey.
