Bill Blackham is one of the seven abductees.


According to, Bill is a slick opportunist whose first priority is himself. Blackham describes himself in Episode 1 as a "used-car salesman", and stated that the last thing he remembers before finding himself in the hotel was being pulled over by the police in a traffic stop. He proves to be very mistrustful of those around him.

In Episode 3, he laughingly tells Charlie when he asks, that he is not a car salesman.

In Exit One, he blackmails Charlie to start a chain of private parks called Freshairrr, that is, until Charlie smothers him with a pillow almost to the point of unconsciousness.
