J.D.

Jason Dean, best known as J.D. is the main antagonist of the 1988 film, Heathers and is portrayed by Christian Slater. He falls in love with Veronica Sawyer, kills three students who hurt Veronica and finally attempts to kill Veronica and blow up the school before ultimately killing himself.

Early Life
J.D. is the son of Big Bud Dean, the owner of a demolition company known as Big Bud Dean Construction. J.D. has moved 7 times before, most notably to Dallas, Baton Rouge and Vegas, before landing in Sherwood, Ohio.

J.D.'s relationship with his father was severely affected by the suicide of his mother who knowingly walked into a building that Big Bud Dean had prior rigged with explosives. It appears that his life and mental state were a lot more balanced prior to his mother's death.

It isn't known if J.D. has killed prior to Heather Chandler's death. Though it is unlikely due to him appearing to be stunned and not having a plan on what to do next. Despite this, when Veronica asks if he had done this before, J.D. does not give an answer.

Appearance
J.D. is a handsome young man with dark brown hair and brown eyes. His appearance is messy at times, he often wears flannels or old jackets and has a single silver earring.

Personality
J.D. seemed to have been pretty average and happy before his mother's death. When the film takes place, he is a young man who seems to suffer from mental illness.

Heather Chandler
The night of the Remington University party, J.D. and Veronica play a game of strip croquet and Veronica makes a comment about how she wished to see Heather puke her guts out. The following morning, J.D. and Veronica make a plan to do just that. Among other suggestions, Veronica decides to give Heather a wake-up cup of milk and orange juice despite J.D. wanting to give her a cup of blue liquid drain cleaner.

Despite Veronica telling J.D. no to his idea because Heather would never drink a mysterious blue liquid, he still fills a solid mug with the drain cleaner. While making out with J.D. in the Chandler's kitchen, Veronica mistakenly grabs the cup of drain cleaner instead of the milk and orange juice. J.D. notices, but decides not to say anything and instead suggests he carry the cup as it would go along better with their plan. J.D. tricks Heather into drinking the drain cleaner by calling her a chicken, she starts choking and falls into a glass coffee table. The two panic and covers up the "accident" by staging it as a fake suicide. Veronica asks J.D. if he had ever done this before to which he does not reply.

Kurt Kelly and Ram Sweeney
J.D. plans Kurt Kelly and Ram Sweeney's "suicide" after Kurt tells the entire school that Veronica had given him and Ram blowjobs during their double date with Heather McNamara. J.D. convinces Veronica to forge a fake suicide note that explains they're "gay" and collects "gay paraphernalia" to stage the scene. J.D. tells Veronica that he has something called "ich lüge" bullets and that they would only stun Kurt and Ram, but not kill them and she believes him. Veronica calls Kurt, inviting him and Ram to meet her for sex. Little did Veronica know that ich lüge actually means "I lied" and that those bullets were very real.

Veronica meets Kurt and Ram in the woods behind the school and has them strip to their underwear. She has them count to 3 so they can strip her clothes off of her. When they got to 3, J.D. jumps out and shoots Ram in the throat, killing him instantly. Thinking it's all still just a joke, Veronica shoots at Kurt but misses. Kurt runs off and J.D. chases him back around to where Veronica is sitting with Ram's body. In a panic, Veronica shoots at Kurt hitting him in the heart.

Westerburg High Bombing and Suicide
After Veronica breaks up with him, J.D. decides he is going to kill all the students of Westerburg High and comes up with an idea for a bomb after watching one of his father's demolition videos. While watching the video, his father states he put a Norwegian in the boiler room, then put thermals in the floors above to go off after the first bomb. J.D. blackmails Heather Duke with a picture of her and Martha Dunnstock from when they were friends in their childhood. He uses her powerful influence to spread a petition around the school. The students believe the petition is to get the popular band Big Fun to play at their prom, among various other things, but it's really a mass suicide note for when the school blows up.

The night before the bombing, J.D. stops by Veronica's house telling her parents that she plans to commit suicide and leaves a note saying "recognize the handwriting?" After going to her room, Veronica finds that J.D. left a doll hanging from the ceiling by a noose with a shirt that says "Big Fun" on it implying that he intends to kill her. J.D. sneaks into her room with a gun later that night intending to do just that, but Veronica has her own plan. Veronica makes a noose out of a sheet, tying it around her neck and her waist to hold up her weight without actually killing her. Believing Veronica is dead, J.D. reads aloud the actual petition the students signed and leaves when he hears Veronica's mom calling for her.

J.D. plants the thermals underneath the gym bleachers and in the boys bathroom on the day of a pep rally. Veronica stops him as he is heading down to the boiler room, pulling a gun, but J.D. knocks the gun out of her hands and knocks her out. J.D. sets up more thermals in the boiler room during the time Veronica is out cold and begins a timer for 2 minutes and 30 seconds. Veronica comes to sneak up on J.D. and hits him with a fire extinguisher. The two briefly fight again causing the gun to be thrown across the room. Veronica manages to get the gun, shoots off J.D.'s middle finger, pries out the information on how to shut the bomb off from J.D. with only 4 seconds left to spare and shoots him again in the chest.

Veronica, believing J.D. to finally dead, leaves the boiler room and the school without being noticed. While walking down the school’s front steps, J.D. stumbles out behind her. J.D. tells Veronica that she f****d him up pretty bad, has a power that he never thought she possessed and that the slate is clean as he activates yet another bomb strapped to his chest. J.D. asks Veronica to pretend he did blow up the school, all the schools and that now that you're dead, what're you gonna do with your life. Veronica replies by putting a cigarette in her mouth. The bomb blows up, lighting Veronica's cigarette and ultimately ending J.D.'s life.

Veronica Sawyer
J.D. catches the eye of Veronica during one of Heather's lunchtime polls. The two briefly flirt before Veronica is pulled away by Heather. The two meet again at a Snappy Snack Shack where J.D. buys Veronica a cherry slushie and talks with her some time before she heads off to a party at Remington University. Later that night, J.D. climbs through Veronica's window and asks her to play a game of croquet which turns to strip croquet.

Veronica breaks it off with J.D. not long into their relationship due to him murdering three of their classmates. He continues to try to win her back with no avail and eventually decides to kill her, too. Upon getting to Veronica's house, he finds that she has already "committed suicide", so he reads his plan to blow up Westerburg High to her "dead" body. The following day, Veronica finds J.D., shoots his finger off, deactivates the bomb and finally shoots him in the chest, leaving his body in the boiler room. J.D. follows her outside where he finally blows himself up using the bomb he had originally intended for the Westerburg High student body.
