I'm in a new environment and some of my dissociative bits haven't adapted yet so parts here are missing. It would be characters from the story, unmonitored by [bB]oss due to things having gotten funny in some areas, playing with the violent research program.
A and B are sporadically laughing their heads off, while doing strange behaviors at each other and the computer system.
C: what's so funny?
B: the joke is that you [bursts with laughter] can't talk about the joke
A: or [bursts with laughter] even laugh at it!
[somebody interacted with karl around this point and the story desynchronised. the joke is coverup mind control, and the idea of it covering itself up inside itself etc etc and analogy jokes around the mind control pattern, inversions of control]
