Ah, I see. I may have chosen 4B if I turned up my sound, but it was nighttime for me so I had sound pretty low.
Still, I feel like this ghost wasn't exactly mischievous. I didn't feel any sense of a playful nature in it. Well, guess that's an instinct issue.
Hm... Welp, I guess I'll choose 4B if the ghost reappears. I wonder if John Chapters could just beat the ghost up into mush using Ghost Hands. It seems perfectly capable of interacting with the ghost 'physically', and restraining it easily.
