In Book One, Stanley is aware of Sizemore's existence, but cannot be bothered to remember his name. Sizemore seems completely resigned to Stanley's abuse as he is to everything else. He perks up even at the brief acknowledgment Stanley gives him when he returns to Gobwin Knob. Sizemore does give Stanley a much-needed morale boost when he and Maggie remake the city of Gobwin Knob with a heavy Stanley Is The Man influence. Obviously, Stanley has no idea of this.
