"If only you could talk to the monsters..."
I haven't actually played Phasmophobia myself, as I don't really have anyone to play it with, but it's made the rounds among the streamers I watch and used to watch, and this particular realization hit me last November when I was checking out Dan Jones' stream of it.
I had half a mind to have the ghost be a cameo of another "dead" character of mine, but I'm not quite that mean. Plus you know what they say about jokes and moving parts.
