- "Get her away from him!"
- —Jameson referring to Penny as she tries to attack him and the Governor's men.[src]
Nothing is known about Jameson's life before or as the outbreak began. He may have lived in or near Woodbury before the outbreak.
Jameson survived the outbreak, making it to Woodbury. He, along with Bruce and Gabe, find The Governor brutally severed in his apartment. He tells them to get Penny away from him as the other two men overlook him.
Jameson appears once again in a flashback, continuing the scene from issue 33. As a undead Penny begins to attack Bruce and Gabe, he comes up from behind and holds her back. Under orders not to kill her from The Governor, Bruce tells Gabe and Jameson to lock her up in one of the rooms as he goes to retrieve Bob.
When Bruce returns with Bob, Jameson and Gabe are looking over The Governor, unsure of what to do. The two men, presumably, help Bob gather the supplies needed for operating on The Governor.
This list shows the victims Jameson has killed:
- Possibly numerous counts of zombies and possibly unnamed people.
- Issue 43 (Flashback, No Lines)
- Jameson's name was revealed in The Fall of the Governor.
