Both are detectives from well known horror franchises about a serial killer who nobody knows the true identity of (and is a different person in several of the movies), both become a part of this mystery because of the death of someone close to them (Bailey’s son Richie, Tapp’s partner Steven) in an incident involving the killer (though Richie was a Ghostface while Steven was chasing after Jigsaw) that caused them to go slightly crazy and dedicate their life to getting revenge on the one who killed them (Samantha and Jigsaw), unfortunately both were unable to and ultimately ended up getting killed near the end of the movie.
I think one of the reasons I like this MU is that it can use an important part of the Scream movies that you don’t really see in many of their matchups, the mystery, Tapp spends his entire time investigating and trying to figure out who Jigsaw is, so, what if instead of Jigsaw, it was one of the Ghostfaces?
