10. Beth LeBeau
A cold open death at the beginning of the episode sees the demise of Beth LeBeau, who was a close friend of a mysterious figure named Georgia Madchen.
Madchen had a disorder that eventually drove her insane, as she could not recognise faces. Beth LeBeau receives her grizzly end when Georgia burst into her home as she was settling in for bed, able to somehow able to sneak past her and hide under Beth's bed.
Beth walked back into her room, following Georgia's wet footprints, and then is grabbed and dragged under her own bed screaming. All we see at that moment is a lot of blood spraying out from under the bed, but when Will goes into Georgia's mind to reenact the crime we are given more of the grizzly details.
It turns out Georgia used a knife to cut Beth's face wide open in a fashion similar to the Glasgow Smile - which causes similar wounds to the scars the Joker from the Dark Knight has. Beth's death is very bloody, but also even more messed up because Georgia inadvertently killed her best friend without realising it because of her condition.
