PRESENT Employee IDs 141, 884, 426, 112
ABSENT Employee ID 189 (Sick Leave)
ID 426: So... Operation Traffic Light was a bust. Think, people! If we keep messing up, we'll never solve this before the other strike teams. I'm not letting 427 figure this out first.
ID 884: Perhaps we should not assume insects can only perceive fast-moving objects?
ID 141: But, the data doesn't lie! All our research shows insects see things at a different speed than mammals. It's settled science.
ID 884: Evidently this is not consistent across the spatial displacement spectrum, judging by our colleague's emergency visit to the hospital.
ID 426: What did you tell the EMT by the way?
ID 112: Tiger attack.
ID 426: Wow. | Key Items | |

Have I seen it? It’s huge! There’s candle wax everywhere. And the big portraits of those dead kids I mean.
Those poor kids, man. I can’t believe they would just straight up kidnap children. Glad those four made it out alive and took down Schmector.
Thank God Ominent’s not evil anymore. Although they do make us replace our names with numbers, though. That’s creepy.
It’s just for safety. So nobody can blackmail us. Out here I’m not “Thomas” or “William,” I’m just Employee 761. My number is like a security blanket. | Key Items | |
