Alan Park was a supporting character in Season 2 of Terminator: The Sarah Connor Chronicles. Appearing in the episode "Earthlings Welcome Here", he was a blogger who began living off the grid as a woman by the name of "Eileen" following his resignation from a highly secretive job. Alan had been working as a metallurgist, studying an alloy being used by his employers for an unknown robotics project.
Park met Sarah Connor at a UFO convention and promised to arrange a meeting with Abraham, his alter ego. He eventually revealed that he was, in fact, Abraham, when they were at his trailer in the desert. He and Sarah worked out the details of his past abductions, and the location of his studies through his consultations with Barbara Morris, a psychologist. While Sarah listened in on the sessions, she heard a struggle and a few muffled shouts. When she went to investigate, she found both Alan and Barbara dead from gunshot wounds.
