Yeah, that was what u was thinking with Sofia, Liz, and Rachel each having their own spheres of influence and are enemies. Soft a managed to get in close to the player character to help take down the other pranks to be the last one standing. There is also mention of the tapes being deleted from the last case which would have been her. Some people not completing correctly could be a bug, I changed around how some of that works in the last few hours to make the mechanics more consistent, but something could have slipped through the cracks.
