At the end of the game, her father Eli is killed by an Advisor before she and Gordon get into a chopper to go looking for Dr. Mossman. While she and Gordon watch, helpless, pinned down onto the walls by the Advisor's psionic powers, Dog jumps through the roof and attacks the Advisor before it can do the same thing to Alyx and Gordon, severely injuring it causing both Advisors to flee. Alyx cries over Eli's body as Gordon passes out and the credits roll.
