Renton's Grandfather is a gruff, no-nonsense mechanic who knows his way around an engine better than most people know themselves. He's not the warm type—honestly, he can be pretty difficult to deal with—but there's real affection buried under all that gruffness. He's made it clear he doesn't want Renton following in the footsteps of his father Adrock or his sister Diane, though he hasn't always been explicit about why. What matters is that despite his cantankerous nature, he's got Renton's back. He'll support whatever path his grandson chooses, even if he doesn't always say it out loud.
