of Part II. Her father, Jerry Anderson, was a Firefly surgeon who Joel killed at the end of the first game to save Ellie. Four years later, in her early twenties, she tracks Joel down and beats him to death. Some time later, back in Seattle, Abby learns that her ex-boyfriend Owen has gone missing while investigating the Seraphites. The WLF leader, Isaac Dixon, believes he may have defected, and plans to assault the Seraphites' island settlement.
