Alright, so I met the Tchortling Devourer called Detritus in the lower area of some mutagen tanks. Poor guy apparently got a pretty bad deal out of joining the Institute, I feel kinda bad for suckering him in for the Investigators now. I killed him to put him out of his misery (and because I needed to get to some containers) and after coming back another time, I found that he was alive, while his previous incarnation's corpse was lying next to him. I think he should be made non-respawning, shouldn't he?
