After the Striders are dispatched, Gordon returns to the Base and receives an unexpected thanks from Magnusson. Before the rocket launch and out of Alyx's earshot, Eli tells Gordon that he believes The G-Man's message is a warning regarding the Borealis, telling Gordon to destroy it and promises to elaborate further. He then tells Gordon that he is very proud and thankful of him, saying he "couldn't be prouder of you even if you were my own son". The rocket is then successfully launched, closing the superportal and preventing the Combine from calling in reinforcements from their homeworld. Alyx reveals that she found and fixed up an old helicopter that they can use to fly to the Borealis.
As Gordon and Alyx prepare to depart to search for Dr. Mossman, Advisors attack the helicopter hangar. They telekinetically pin Alyx and Gordon to the wall and seize Eli. Eli warns them both that the Borealis must be destroyed and then tells Alyx he loves her and to look away as the Advisors proceed to kill him, probing his mind in the process. Dog arrives and fights off the Advisors, forcing them to escape the hangar and freeing Gordon and Alyx from their grasp. After they fall to the floor, Alyx runs to her father's side and holds onto his lifeless body. As Alyx cries over Eli, the screen fades to black and the credits roll.
This chapter contains examples of:
- Please, Don't Leave Me: Alyx says this to her father after he's killed by an advisor.
- Post-Climax Confrontation: After successfully fighting off a force of Combine Striders, the White Forest rocket launches safely and successfully closes the Combine superportal. It seems that you have achieved victory and you are heading off to find the Borealis, that is, until Combine Advisors appear, pinning you against the wall and killing Eli, while you and Alyx helplessly watch. Thankfully, D0g appears, attacking the Advisors and forcing them to flee.
