It's not a long tale to tell but it takes Mohinder the better part of an hour to tell Bruce about how he'd been taken from the lab just after Bruce and Tony left and been given several blind tests through one way mirrored rooms and cards stretching from the inane 'bark like a dog' and 'take off your clothing' to the horrorfying 'put your firearm in your mouth and pull the trigger.'

All three agents in the room had put their guns in their mouths...the test subject (who had an empty chamber) and the two guards who had supposedly been cleared and safe. Mohinder shakes over that, half laughing and half crying.

"It spreads. It spreads, Bruce. Anyone in physical contact with me-- That's why it's not safe."
