Nosebleeds
Whenever Jeremy/Adam kills someone his nose bleeds but whenever he's seen as Adam his nose never bleeds until the end also why was his nose always bleeding in the first place.
- Could it be related to the Nosebleed trope, implying that he is getting aroused by committing the murders?
The Gang of Bullies
How come Jeremy/Adam never went after the Gang of Bullies who beat and stripped him? They're just as responsible for ruining his life as the girls were.- Perhaps he did and they're just out of focus because the film is about Kate and her group.
- So how come it's never brought up?
- Maybe because they're bullies. Even if it's terrible how they died (if they were murdered), they weren't exactly well-liked to be missed.
The Two Dun It theory
So one of the most common theories is that Dorothy is another killer after she is unmasked wearing the killer's costume. There are a few questions:
- Who killed who, that is which ones were killed by Adam and which ones by Dorothy?
- If Dorothy and Jeremy/Adam were working together, why? Why would Adam work with someone who caused him so much pain and planned on killing them anyways?
- Maybe because she was useful. Jeremy/Adam needed a fall-person, and knows that Dorothy would have the right motive to be a suspect.
- If Dorothy was a killer, where did the bruise on her face come from that she didn't have while arguing with Kate?
- Maybe they got into a fight. Dorothy may have found out Adam was Jeremy, leading to a scuffle.
- If Adam was the killer,where was his scar from the pool cue shot administered by Ruthie? Dorothy had a huge black&blue scar on her face when Adam removed her mask, but Adam didn't have one ever.
- Hard Head, possibly another sign to the audience that he's the killer. Kate struck Adam in the same spot with a bottle and it seemed to do little damage (he seems to aim and fire a pistol pretty well).
When was Dorothy knocked out?
If Adam was the actual killer and framed Dorothy then when did he (possibly) knock her out and put the costume on her in order to frame her?
- There's a period of at least three minutes film-wise (possibly more in-story after the caterers leave) after Dorothy storms off and when Adam shows up on the staircase before asking Kate to dance. During that time Kate calls Vaughn and discovers his head outside; she then runs back inside and as she's standing under the hanging metal cupid statue, Adam comes downstairs.
Drinking problem
If Adam/Jeremy is the killer why would he drink heavily wouldn't he need to be sober to kill his victims cause he's shown drinking when Kate finds him after Ruthie's death and afterwards he's shown killing Paige rather effortlessly despite aforementionetly drinking.
- It's unclear how much the drinking affects Jeremy/Adam; he's certainly pretending to be more drunk than he really is later on when he dances with Kate. There's also something to be said to drink in order to blend in while in a crowded situation.
