I'm talking about the girl who got murdered in her own bedroom. Spoilers and big time trigger warning for a graphic fictional murder in a movie:
I forget exactly what happens, but something like this: clown chases her to her bedroom, and gets her face down and just starts slicing and dicing her back, cutting off skin. Then he slices her face, taking out one eye in the process. Then he splits apart the fingers of one hand, ruining it, then he literally rips off her other arm. Then he scalps her, leaving her bloody skull exposed. He finally leaves the bedroom, and the girl is still alive, and struggles to her phone, where I think her friend is calling. Then at the very last moment, the clown busts back in with a jug of salt in one hand and a jug of bleach in the other, and pours it all over the girl's wounds. Later on in the movie, the girl's mom comes home, goes up to her bedroom, and finds the clown just chilling with her daughter's mutilated and fucked up dead body. But then bam, and the girl breaths, because she's still alive. Mom's death is off screen, but later on trick or treaters ring their door bell, the clown answers and gives them candy out of the hallowed out head of the mother and everyone is all smiling and laughing.
