Okay I didn’t know how to articulate this without this being really long so here’s a list of the characters and my reasonings for how suspicious I think they are:
Deion - Obviously I don’t suspect Deion. I don’t suspect him for the same reasons you wouldn’t suspect Sydney in the movies or Emma in s1 and 2. He’s the “Final Girl” (or Boy in this case). But I do think it would interesting and shocking if he was the killer. Obviously there would HAVE to be two killers, but there always is at least two killers, so.
Kym - I don’t know why, but I don’t suspect Kym at all. She’s not on my suspect list at all. Except if Manny is still alive and they’re teaming up for some reason. And if Marcus is really dead.
Manny - Speaking of Manny, you may think “but he’s dead??” And yeah, they SAY he’s dead, but we didn’t see him die or his dead body. Yeah, sure, he blew up in a car, but they didn’t show him immediately before the car blew up. They showed him coughing in a car on fire, but then they showed Kym, Amir, and Beth talking, and THEN the car blew up. Plenty of time for him to have escaped the car with help from the other killer (maybe Kym? She showed up after Beth and Amir).
Beth - I don’t know about Beth. I really only suspect her because of all the horror movie stuff, and she’s labeling everyone, but I don’t know. I was thinking about if she teamed up with Liv’s dad but that wouldn’t make any sense because Beth and Amir got attacked at Beth’s house after Liv’s dad was stabbed.
Liv’s Dad - He is very suspicious with taking Deion to the park. And him getting attacked doesn’t mean anything since it’s not uncommon for the killer to have the other killer attack them. I don’t know what his reasoning would be, but he’s a cop so he has access to peoples’ records and stuff so he’d know about Marcus.
Liv - She liked Deion from the beginning so her reasoning could be that and she never actually intends to kill Deion, just the people he’s close to. She could be obsessed with him and stalked him to know about him and Marcus. Avery was mean to Deion and then he died, so maybe that could go back to her. Plus her dad said that she went crazy after the divorce, but that could always be her dad trying to push off the guilt on her.
Amir - Obviously Amir is dead dead so I don’t suspect him, but I didn’t really suspect him anyways.
Shane - Again, Shane’s dead dead but as soon as the group tied him up in the school I stopped suspecting him.
Marcus - We’re supposed to think he’s dead, but I don’t know if I buy it. For me, it all goes back to how does the killer know all that stuff about the night of Halloween. Obviously his reason would be that he’s pissed at Deion for ditching him. If it is him, I have him teamed up with Manny. I just don’t believe that Manny’s actually dead.
Jamal - So I hope he’s not the killer, as the half-sibling being the killer is the storyline for Scream 3 and Scream s1, but if it is it can still work. It’s plausible to think that Deion told Jamal about that night, so he knows about the costume, the candy, everything. And there can be a couple different reasons. The first one would be boring, that he is pissed that Earl left his mom after Marcus died so he wants to get back at Deion. But the more interesting one could be that he wants to be close to Deion. It was said a coupe times that he is the only brother that Deion has now. So maybe he wants that relationship with him, he wants to be close with him and killing all his friends and giving him that trauma is the way to do it.
