-Wait, please... —Mark's last words to Selena, he is infected, and before ampatuted arm and stabbed head to death.Mark was a survivor of the Rage Virus after it originally decimated Great Britain, until he was infected, and killed by Selena.
Mark and his family were in London at the time of the Original Outbreak of the Rage Virus, and his father, who was presumably rich, held onto his money even though "cash was completely useless." Mark and his family attempted to reach the airport and evacuate Britain by getting a train there from Paddington Station, but over 20,000 people were at the Station as well.
When the Infection began to spread through the crowd in the train station, Mark survived by climbing up upon the thousands of bodies on the ground, onto a kiosk. Mark then saw his father among the crowds, and it is suggested that he was either infected or mutilated. Sometime after the exodus, Mark met Selena somewhere in London and the two made it their mission to fight and kill the Infected.
On Day 28 of the outbreak, Mark and Selena saw Jim being chased through the streets by several Infected. The two set about saving Jim, and Mark incinerated the Infected that were chasing Jim with cocktails and bombs. Mark and Selena then lead Jim down to the London Underground, and returned to their hiding place in a sweet shop. There, Mark introduced himself and Selena to Jim, and then explained to Jim what had happened in the past twenty-eight days. Jim then convinced Mark and Selena to travel with him to his parents' house in Deptford the next day to see if his family were alive.
At Jim's house, Mark, Selena and Jim found the corpses of Jim's parents, and when Selena told Jim that he should have been grateful that his parents had died peacefully, Mark recounted what had happened at Paddington Station when he and his family were trying to escape England. Mark and Selena then slept on Jim's couch as it would be safer than being in different rooms. While Mark and Selena slept, Jim unintentionally attracted two Infected, which attacked Jim. Mark and Selena fought the Infected off, with Mark killed Mr. Bridges' infected daughter by stabbing her to death; but in the process, Mark was apparently injured and infected, and he had last to looks Selena. Selena amputated his arm, stabbed his head, and hacked him to death with her machete.
- The wound on Mark's arm through which he was apparently infected looked more like it was caused by a shard of glass than a bite.
- This would mean that Selena unintentionally killed Mark even though he wasn't infected.
