Reilly (portrayed by Lane Miller) was a minor character from the eighth season of The Walking Dead. He was a member of the Saviors who had been captured by the Militia after his outpost had been taken out. For a time, he and his cohorts were imprisoned at the Hilltop Colony, but escaped following an attack led by Simon.
In the episode "Still Gotta Mean Something", Reilly, Jared and six other Saviors who had escaped from the Hilltop had holed up in an abandoned dive bar while they planned their next move. Two of their number had been bitten by walkers while they were on the run and had to have their wounded limbs amputated to save their lives, leaving them in no condition to travel. Rick Grimes and Morgan Jones had gone in search of them, but while they were observing a nearby herd of walkers, the Saviors ambushed and captured them.
Rick and Morgan awoke to find their captors arguing amongst themselves, with Reilly suggesting that they cut their losses and run, leaving their captives behind. Jared, on the other hand, wanted to bring Rick back to the Sanctuary to gain Negan's favour. However, after waking, Morgan began shouting at the Saviors and his cries drew the nearby herd towards them. As the zombies attacked, Rick urged Reilly to free him and Morgan. Reilly did so and Rick began shooting at the incoming zombies, although half the Savior group had already fallen to the undead. Rick then turned on the Saviors by hacking at Reilly with a hatchet and shooting three other Saviors, with Jared managing to skulk away, although he would soon die as well. A short while later, a dying Reilly lay on the floor and told Rick that they could have lived with his community. Rick's only response was to raise his Magnum and shoot Reilly in the head.
