Since Pix withered away and lost the crown, I had this AU forming in my head. I wanted to get it out here, and I'm working on a fanfic of this AU for myself. I might post some chapters, but I might just leave it as this.
Suspects: Scott, Katherine, Sausage, Shelbie, Joel
Detectives: Jimmy, fWhip
Victim(s): Pix, maybe Joey and Lizzy
Side characters: Oli, Gem, False
Pix would get murdered either at his museum, or at the tea party Katherine held. Jimmy would arrive a couple hours later, and the investigation would begin. Scott would be interviewed first seeing as he just acquired the crown Pix had before. Katherine hosted the event, so she'd be second on the list. Sausage handed out drinks, so if the cause was linked to poison then Sausage would also be interviewed. Shelbie would've been seen acting off after the death, which would make her a mild suspect. And Joel would be interviewed by fWhip because Joel would mock Jimmy to death before spilling any important info.
Joey or Lizzy could die next, Lizzy as a means of hurting Joel, and Joey as a means of directing the murderer to Shelbie or Katherine.
Oli would try to calm the group down, and would offer some help to Jimmy and fWhip, but ultimately wouldn't help much. However, he would still be useful as he'd be the one to potentially intervene during a heated argument between the cast.
False would provide some insight into Pix just...as a character, and try to provide motives for the others. She'd mostly try and stay out of the whole thing, but would pitch in when called upon.
Gem would give a detailed account of the night and be a useful witness, because I think she'd be observant enough to notice some small details prior to Pix dying.
That's it! It's not a ton of stuff, but I still think it's pretty fun.
Bye, have a great day/night!
