Cal Hampton appears with a named biography on Rockstar’s official Grand Theft Auto VI site. That public first-party page is the reason he is in this encyclopedia. Unnamed extras in trailer frames are not.
Rockstar’s copy is specific and small. Cal is Jason’s friend and a fellow associate of Brian’s. He feels safest hanging at home, snooping on Coast Guard comms with a few beers and private browser tabs open. Casual paranoia “loves company,” while Jason has bigger plans.
The official site also gives him two quoted lines about birds in formation and psychopaths in charge. Those are flavor. They are not a confirmed conspiracy mission, a radio show, or a skill. Map-6 will not inflate a bio paragraph into a faction.
Because Rockstar published the name and the relationship to Jason and Brian, confidence is confirmed — not “maybe from a paused frame.” We still skip stats, ages, and last-seen locations that do not appear on rockstargames.com/VI or Newswire.
