The Homeless Man was a local beggar who lived around Shaun's neighbourhood. He is seen, along with his dog, begging for change when Shaun is on his way to the shop. However, Shaun drops the change and the man is forced to pick it up.
Unfortunately, the homeless man is bitten by a zombie and becomes infected. The next day, while Shaun is on his way towards the shop, the homeless man approaches Shaun, dragging a dog leash, and attempts to grab hold of him. Shaun, not bothering to look up, thinks he is again begging for change and explains to him that he didn't even have enough money for his purchase at the shop. Later, when Shaun and Ed escape from their flat, the infected homeless man is seen while the two speed away in Pete's car.
