Donald "Don" Harris is a main character-turned-main antagonist in 28 Weeks Later.
Biography[]
Don was the husband of Alice Harris, and the father of Tammy and Andy Harris. Tammy and Andy had gone to Spain on a school trip shortly before the initial outbreak of the Rage Virus. As the virus ravaged Great Britain, Don and Alice were forced to flee from their home but found safety when an elderly couple, Geoff and Sally, allowed them and two other survivors, Karen and Jacob, to take refuge in their barricaded cottage near Sandford, where they stayed for some time. One day, a young boy shows up outside the cottage and begs to be let in, to which Don reluctantly does so. Shortly after, however, a horde of Infected who was chasing after the boy attack the cottage and break down the barricades. One of them bites Karen, infecting her, and Don is forced to out her down with a crowbar. As the Infected break into the cottage, Don tries to fight them off as the remaining survivors flee, but Don is quickly overwhelmed and flees to the upstairs bedroom where Alice is. He tells her that they need to leave, but Alice refuses to leave the boy behind and Don, in a panic, abandons her and flees the cottage through an upstairs bathroom window. He runs through the surrounding fields, chased by a hoarde of Infected, but makes it to a dock where Jacob is preparing to make his escaoe via a motorboat. Don manages to get in the boat, but Jacob falls into the water while trying to do the same and is attacked and infected, forcing Don to abandon him. Don travels down the river until he is eventually found and rescued by the military, who take him into a quarantine camp.
28 weeks after the initially outbreak of the virus, all the infected die from starvation, and Don has been appointed as a station officer to help the army rebuild the city. He reunites with his children in District One and takes them to his penthouse apartment. Afterthey ask about their mother, Don lies and claims he saw Alice get bit and that there was nothing he could do to save her. The next morning, however, Tammy and Andy sneak out and go to their old family home to collect photos of Alice, after Andy's expresses his fears that he may forget what she looks like - there, Andy finds Alice miraculously alive in the attic. Shortly after, Andy and Tammy encounter a group of soldiers who were sent by Doyle, who saw Andy and Tammy sneaking out. The soldiers take Andy, Tammy and Alice back to District One, and Don is informed of their discovery. When Don goes to see them, Tammy confronts him for lying as Don tries to defend himself. Meanwhile, the doctors discover that, even though Alice has been infected, she is not showing any symptoms and is perhaps naturally immune to them, meaning that her genes could be used as a cure to the virus.
Infection[]
Don decides to secretly pay Alice a visit, using his special keycard the military gave him to enter the room where she is being quarantined. He apologises for abandoning her at the cottage, and after she declares that she loves him, he kisses her, unaware that she has the virus. Don is promptly infected and quickly kills Alice before infecting a few soldiers. The rest of the soldiers take the survivors into a parking garage in an effort to control the situation, but Don gets into the parking garage and infects several more people. As the situation gets more and more helpless, the military eventually resorts to dropping fire bombs District One, killing countless Infected and uninfected civilians, but Don survives the bombing.
