Someone is decapitated off screen and the head is thrown at two other characters. It happens right after they call "Miss Iza?" The head looks very fake though
It's basically the one girls whole character, people even look at her funny when she carries a knife. It's also shown as very unrealistic and triggering for viewers who can be effected by this.
A teenager in a sleeping bag is hit repeatedly against a tree. A woman falls down basement stairs and her legs are broken. A girl gets a rod shoved through her mouth. Lots of random bones everywhere. Someone is fed into a woodchipper having had their eyes gouged out.
