Claim: Giant Bill
Any attempt to quantify what makes a dwarf a dwarf will eventually refer to their short stature, and while this is far from their only characteristic it is the most applicable to Will. As hard as it may be to believe, Will is not in fact a dwarf. He is a small human child who persistantly resists instructions to stay at home, preferring instead to run around having fatastic adventures and pretending to be a burly dwarf. Will always keeps a constant eye out for his big brother Bill and is always quick to rush to his side and try to get him caught up in whatever mischief has him occupied.
