Billy is autistic ♾

Just me rambling about an headcanon I take wayyyy too seriously :)

Hyperfixation : horror movies (obviously)

He just keeps talking about it. All the time.

Also him using his hands while talking in this scene

(There's also something to be said about him mentioning the queer actors and not the 'straight' characters but that will be for another post-)

Also in the phone call where we're sure it's him :

(If he was the one calling Casey then there's even more-)

Also him just constantly talking with movie-related things : "It was edited for TV- all the good stuff was cut out", "nice solid R rating, on our way to a NC-17", "lately we're just sort of edited for television", "Maybe your movie-freaked mind lost it's reality button","It's all a movie, it's all...one great big movie.Only you can't pick your genre","I think she wants a motive","I don't really believe in motive, Sid.", "See it's a lot scarier when there's no motive Sid", "Is that motive enough for you ?", "How's that for a motive ?", "Just pretend it's all a scary movie Sid...How do you think it's gonna end ?", "Perfect ending.", "Now Sid, don't you blame the movies. Movies don't create psychos, movies make psychos more creative !" and basing his killing spree on horror movie tropes : phone calls, masked killer, virgins being the final girls (literally having sex with Sidney to fulfill the trope), 'no motive' etc...

2. Abnormal posture

3. Staring (last 2 photos, both scenes in Sidney's room, police station scene...basically when there's Sid) or excessive blinking (doorway scene, kitchen scene...(basically when there's Stu)

4. Plans and changements

Billy (and Stu) planned their entire killing spree (from the dates it would be on : surrounding the one year anniversary of Maureen's death, to the person they would frame and his supposed motive as well as Casey and Steve's murders with the phone call, the attack at Sidney's house, Billy's incarceration, Stu's phone call following it, Billy's fake death, kidnapping Neil before his flight and using his phone, hiding his car, using a voice changer, stabbing each other to seem like victims, the party etc...)

When Billy's (and Stu's) plans get changed (Dewey, Gale and Kenny being present, Sid escaping the kitchen with her dad and Stu losing too much blood), Billy panics and goes into what could be defined as a meldown : throwing out insults, walking in circles, never going to check on the first floor, destroying Stu's living room and just panicking all around-

(When he fails getting Sidney to trust him and makes her escape to the toilets, he punches himself in frustation)

5. Insociability

Basically doesn't talk in the fountain scene

Awkward and Unsettling while talking, even to his friends

Doesn't pay attention to girls being interested in him

Doesn't seem at ease with the number of people leaving the party

(Even fidgeting though that may be just be him checking that the people are leaving for real)

6. Overdramatic

7. Favorite person/people

Okay this one's not that common in autistics but for Billy, he definitely has a special person, two in fact :

He literally started killing because his mom "moved out and abandoned" him.

For Stu, I will be vague cause I'll talk about it in detail in the other post 👀but basically he's not really himself unless Stu's there and planned a killing spree where only they would survive (+ trusted him to stab him).

Bonus : If Billy is the one who called Casey

"I only eat popcorn at the movies" Well I'm getting ready to watch a video "Really what ?" Oh, just some scary movie "You like scary movies ?" Huhuh "What's your favorite scary movie ?" Hum- I don't know... "You have to have a favorite, what comes to mind ?" Hum...Halloween ! You know the one with the guy in the white mask who walks around and stalks babysitters. "Yeah." What's yours ? "Guess." Hum- Nightmare on Elm Street ! "Isn't that the one where the guy had knives for fingers ?" Yeah, Freddy Krueger. "Freddy, that's right. I liked that movie.It was scary." Well the first one was but the rest sucked."
