Question: I don't get the ending. We see Adam shot the masked person who is Dorothy, so I figured the killer was Dorothy, but reading a correction entry it states that it's obvious the killer was Adam. If the killer was Adam then how did he get Dorothy in the suit and mask and then make her attack her friend before shooting her?
Answer: There's a deleted scene which shows Adam attacking and putting the costume on her.
Answer: The first chapter shows Jeremy Milton as a boy getting attacked and in the background there is a person wearing the mask at the party. Weird considering the mask wasn't suppose to come around for 13 years.
What exactly do you mean about the mask not coming around for 13 years. The whole reason he chose that mask was because it was at the Valentine's Day dance when they all accused him and beat him.
Answer: Both were working together because both experienced rejection and both concealed their distaste towards their fake friends equally. In the beginning just before the first murder she (the med student) put the knife on the belly button getting ready to make an incision. Guys are hairy down there unless they shave, even then you can still tell. Also, girls' skin texture is different from that of a man. This includes the abdomen. That was a feminine abdomen. I'll add to this more, you saw how the masked killer was stabbing the body bags. There was some struggle in the stabbing since women are not as muscular and women move differently compared to men. Also, remember the scene at the house party in which the women hit the masked killer with a poolstick over the head. After the mask killer kills her, in the next scene you see Dorthy checking her head in the mirror as if she is looking for a mark.
Answer: Why didn't she scream or say it's me Dorothy or even just take the mask off.
When Dorothy fell and then regained consciousness it took her a few seconds for her to come round and Adam shot her before she had time to sat anything at all or either Adam and Dorothy may have been working together.
Answer: Well you're all forgetting about the parents. Unless Jeremy had some sort of record the school and their parents would discover the truth thus making his imprisonment not needed.
Question: Why doesn't Adam kill Kate? Is it because at the start of the movie she said that she would dance with him later or simply because she is his girlfriend?
Answer: He doesn't kill her because she was the only nice one, whereas her friends( Paige, Lily, etc.) were all mean to him at the beginning.
Answer: Plus, Kate was his biggest crush. She was the only one who didn't testify against him and blame him about what happened with Dorothy too.
Question: Whenever Adam / Jeremy Melton is the killer and he kills one of the girls his nose starts to bleed, obviously from all the stress he has to go through to kill them. But whenever he's not the killer, why doesn't his nose bleed? Until at the very end when his nose starts bleeding on to Kate.
Answer: Plot hole? Or perhaps Adam's / Jeremy's nose was bleeding because he was about to snap Kate's neck. Or it was because he was so happy.
He killed Dorothy at the end that could be why his nose bleeds.
Answer: Paraphilia is a condition characterized by abnormal sexual desires, typically involving extreme or dangerous activities. He technically "got off" when killing people.
Question: I came up with a theory: Jeremy Melton is not the killer, the boy with the mask at the prom is, and this is Adam avenging his friend. Jason Marquette is Jeremy Melton who still is a ladies' man who's constantly rejected by women. That explains how both share the same initials, why he disappears after dating Shelly and the next time we saw him was at the art show where he was staring like a creep at the girls, I know this was meant to be a red herring but what are the chances? Also this would explain how little resemblance Jeremy and Adam have, no surgery in the world could make you look like David Boreanaz. So my theory is that they worked together. The only problem with this theory is the nose bleeding but anyone could have a nose bleed at anytime. My question is does this theory hold up?
Answer: That would all check out, but the hole in this theory is that Jeremy has nosebleeds throughout his life, and it is unlikely that Adam, his avenging friend, has the same condition.
Answer: I agree.
Question: If the killer was Adam wanting revenge for the dance, why did he kill Campbell and the other woman we see him drag through the door, who I assume is Dorothy's step mum? But if Dorothy is the killer, why kill her boyfriend?
Answer: I think that the corpse the killer was dragging when Ruthie saw him was the maid.
Maybe Adam made the thing stop working because wanted Dorothy to go down and fix it herself, so he could kill her, but instead obviously without knowing the killer was there Dorothy instead asked Campbell to do it because she didn't know how, or she just simply didn't want to. The killer/Adam might have already been down there waiting for Dorothy but instead seen Campbell but still decided to kill him just because.
Answer: Adam killed Campbell to make sure he wouldn't interfere with his plans. The presence of Campbell's head at the house probably means that he had come by to guard or to snoop. As for Dorothy's stepmother, Adam most likely killed her to both empty the house and to further frame Dorothy as the killer - after all, Adam has no (apparent) reason to kill her, but Dorothy does.
Adam didn't kill her step-mom. That was the maid he was dragging up the stairs. Campbell was killed in the basement when he went to relight the pilot light. The head that Kate found was the detectives head who was coming to help them after telling them they had released the man they thought was the killer.
Question: What was that scream at the end? Was that Kate's scream? If so, why did she scream? What happened to her at the end?
Answer: At the end, Kate thinks the mystery of the masked killer has been solved - "Adam" has framed Dorothy. But, of course, the viewers know that the killer is actually Jeremy, who suffers from nosebleeds in times of distress. As Adam's nose starts to bleed (onto Kate's cheek) at the end, it is revealed that he is in fact Jeremy after all. The scream is most likely just added for dramatic effect and not actually Kate since, while we know she's in danger, she remains blissfully unaware.
Answer: Unless he does kill her because his bleeding nose onto her would make her aware of his true Identity and he would kill her to conceal it.
Answer: The killer is Adam who was previously Jason. He has had plastic surgery. Dorothy was framed by him.
Answer: It wasn't a scream at the end, it was the music. I think Adam only killed the three girls, and Dorothy killed the rest.
I don't think Dorothy killed anyone, she was just framed by the killer so Kate would think it was her when it really wasn't.
So which killer is more likely to have killed Scary Gary (the guy trying on Kate's underwear and got beaten to death with an iron)?
Question: I wanted to know what Dorothy means when she tells Campbell "don't worry about it" when they're lying in bed? Is she referring to him not having a gift for her at the time or something sexual? That part always confuses me.
Answer: Campbell couldn't get it up when they tried having sexual intercourse. Probably because his mind is mainly focused on getting all of her money in her trust fund.
Answer: I think he wasn't really attracted to Dorothy and was just using her for a place to stay perhaps and try to take her money.
He couldn't perform and she forgave him.
Answer: If you remember, Dorothy kind of stumbled into her friend from around a corner before they both fell down the stairs. Adam could have quite easily forced her into the costume and then pushed her, making her seem like she was trying to attack her friend.
