Girl in the walls' Brother

This unnamed boy was the brother of Lizzie Gibson.

Overview
Lizzie and her brother were the result of an incestuous rape by Bill Gibson upon his daughter, Rebecca.

The two siblings were forced to live inside the walls of the house, where they consumed rats and wore rags. They never studied or went outside.

One day, Lizzie decided to kill their father/grandfather, leading to an investigation by Sam and Dean Winchester. The siblings began harassing the Carter family, who intended to move into their house, leading Sam and Dean to fight the siblings off.

Both siblings were eventually killed.
