Events Leading Up To GTA 4[]
(Friendship With Luigi Goterelli): Although there is a major age difference I believe these men are related due to there accents and may of had an unknown friendship with Claude. Jon does seem like an old 18 year old and due to the fact Luigi Goterelli owned a sex club maybe Jon Gravelli was a member and would also have a friendship with 8 Ball.
