Jason is just below average height, well below average weight, and looks much softer than he is. His eyes are such a dark brown, his pupil is barely discernible from his iris. His knuckles are scarred, his fingers host burn marks, and his nose has been broken several times. He dresses business casual in outfits he tailored himself so as to look professional and be able to move at the same time. If he's exhausted himself with magic, he can look a little grey.
