Joe is a mystery. He accepted the COMMUNITY digital implants, so he can access all services, like food and shelter, but he prefers to live outside, ‘under the stars’.
Joe is also a pacifist. He means no harm to any man, and he befriends Thomas Benjamin, just because he’s an outcast. Joe left his reservation behind to come to Vancouver, not to seek his fortune, but to see how the other half lives.
Under psychological pressure, he will reveal too much, but later will totally regret doing so. He’s a straight-shooter, so it would have been impossible for him to lie, anyway.
(He is an unintentional Judas.)
