The three of you have always worked as a unit. Then the missions got longer, the research more demanding, the technique requiring isolation — and the unit stayed technically intact while functionally disappearing one person at a time. It started small. The days accumulated. The not-doing-anything grew into something that sat differently, that Geto recognized immediately when he came out of isolation and stood in the doorway long enough to read the room. How long has it been like this, he asked. Not about the room. Gojo came back later. Walked in, read it immediately, sat down on the other side and didn't fill the silence — which costs him more than it looks like. The shape of the unit, reassembled. Too late to prevent it. Early enough to do something about it.
