Prior to the outbreak, Washington was fighting in Afghanistan along with the rest of his squad which included a lot of members that would eventually become the Reapers. Upon returning from war, he struggled to find jobs or deal with trauma, but the relationship between him and his comrades remained strong. He then decided to become a mercenary.
During the beginning of the outbreak, as Operation Cobalt was put into action in an attempt to try and contain the undead threat, Pope and a group of his people managed to escape the bombings by running until they reached an abandoned church, where inside Pope was amazed to see none of them had been killed or injured, leading him to view him and his comrades as "the chosen ones". It is unknown if Washington was present during this revelation. Regardless, he eventually joined the Reapers, and either found or crafted his own mask with a pure black, featureless expression on it, and would use this mask as a scare tactic against those who were "marked" by Pope.
Washington and at least a dozen Reapers appear on a dark road adorned on both sides with bodies hanging from posts. Suddenly, the Reapers open fire on Maggie and her group, killing Roy and severely injuring Cole. As the Alexandrians flee into the woods, the Reapers chase after them.
After the ambush in the woods, Washington is later present at Meridian, guarding the door to a room when Michael brings Leah to see Michael Turner's corpse. When Leah later tries convincing Pope in his personal quarters that Daryl is a worthwhile recruit for the Reapers, Washington stands by at the ready with his gun.
Washington is present at Daryl's initiation, waiting outside with all the other Reapers for the inductee to pass the test. As Pope declares Daryl "forged by fire", Washington and the rest of the Reapers welcome Daryl with a latin mantra. He is later seen again guarding Pope as he explains to the newest member of the group his past in Afghanistan, his belief in God, and how the group came to be formed.
Washington attends the fireside dinner talking with the others, where Daryl eats his first meal as a Reaper, and subsequently watches in silence as Pope burns Bossie alive, accusing him of turning his back on his brothers and letting Michael get killed.
After Daryl successfully tortures Frost for information as another test by Pope, Washington is among the several Reapers who are sent out to check the house their prisoner had said Maggie and the others were hiding in. Paired up in a squad lead by Leah working alongside Daryl, Carver, Powell, and Fisher, Washington is sent with the last two to breach the back entrance of the home, after which he and his squad-mates check every room in the house before declaring it "clear". Leah sends Washington, Powell, and Fisher to check the rest of the town, while she, Daryl, and Carver stay behind to give the building a once over.
Washington returns back to Meridian at the end of the episode during nightfall, where Pope reveals he further tortured and subsequently killed a now undead Frost, claiming he "got everything he needed out of him."
Washington accompanies Ancheta on a sortie to locate Maggie's group, but fails to find any tracks. For this, he and Ancheta are admonished by Pope, until Leah comes to their defense.
