Episode Assassin

Career assassin and celebrated killer, Gabriel Wesson grows tired of his lifestyle. He negotiates with his Holder (contract employers) to release him from his line of work in exchange for one last, impossible job.

During the job, the target is killed by another assassin. While investigating the body, he happens across one of the office employees (Henry) that happened to be in the room when it all happened. Soon after, the duo come under fire from a mysterious gunman. Having hid in the closet and seen Gabriel's face, the Henry is forced to come along.

It is later revealed that Henry was in fact the real Counter Killer, out for the bounty on Gabriel, and the gunman was merely a distraction hired by Henry.

Henry was hired by Gabriel's employer.

In the end, Gabriel suffers a fatal wound from a surprise attack by Henry.
