Guy's Granda'

AKA, Papa.

He has an ileostomy due to bowel cancer. In Episode 20 the condition of his anus was debated with Guy later clarifying on twitter that it is probably sewn shut.

It is unknown if this is the same granda' Guy cuts the grass for, with his warm beers in the cupboard, and mingin' dirt and detritus-infused ice cubes.
