This is also very interesting how Querthy tells me: Fuck Off, you aren't supposed to be here in the game files.
This one is actually used in game!
There is a TV in a certain, usually blocked room. The TV displays a camera feed from inside the Cell where Qwerthy can be seen flipping off the viewer. If Qwerthy breaks out, however, the camera will break and the tv will display static
OOF, is it perhaps in Jack's Office? (Edit: Found IT)
