Brief description
In s1e7, Kenzo (consultant, spy, and stow-away on the Rocinante) tries to contact "his people" while on the ship, but his cybernetic eye doesn't have any connection. He appears to turn it off when others are nearby, because there's a slight change in his iris that might be detectable. Only when the ship lands at a large space station is Kenzo able to call for help.
