Nothing is known about Alan's life before the outbreak, except that he was a passenger on Flight 462 destined for Phoenix, Arizona.
As Chris investigates part of the fuselage of Flight 462, he finds Alan strapped in his seat, barely alive as zombified passengers snarl at Chris from their seats. Alan begs for help, in which Chris unbuckles the injured passenger from his seat. As Alan tumbles to the floor, Chris notices a spinal injury on his back. Alan continues to beg for help and rejects water, indicating that he wants to be put out of his misery. After some hesitation, Chris bludgeons the suffering man to death.
