It Follows.

A young girl, mourning the recent death of her older brother in a car crash. His best friend, the only survivor of the fatal crash, is sent to live with her family, by her brother's last dying wish.

James is a quiet fellow, keeps himself, you can rarely hear him speak. A tragic past has rendered him mentally incapable of maintaining stable, social relationships. Also, diagnosed with subtle autism, he has trouble putting together sentences, causing him to speak in short, broken sentences.

Eva has trouble accepting her brothers last wish. She hates James. She wishes he would have died in place of her brother. She can't except the fact that James survived.

Upon James' moving in, the Feyette family begin having strange occurrences. Things being moved. Items out of place. Light bulbs bursting. Eva, taking a gander into James' past, finds out more then she needed to know, terrified now of James, she verbally attacks him.

"Why, huh?! Why didn't you die?! Why did my brother die but you lived! I wish you were dead!"She shouts in a teary rage.
She notices him shaking, tripping over his words and trying to form a sentence.
"c-Can't"he says.
"What do you mean can't!?"She cries.
"...i-it won't let..me"
