Enemy Mind
''Spartans Sigrid Eklund and Hieu Dinh are at the Avery J. Johnson Academy of Military Science's firing range in the evening. Sigrid is fully suited up and firing her MA40 assault rifle at targets downrange, while a helmetless Dinh looks forlorn at the empty AI chip in his possession.'' Eklund ceases her target practice. Eklund has removed her helmet. ''Eklund reaches toward's Dinh's hand, lowering it and taking his attention away from the AI chip. The Player's Spartan walks in, and the camera pans around to take their point of view.'' Eklund begins to walk away. Eklund smiles and leaves the scene. ''Dinh picks up a Bandit and offers it to the Player's Spartan. They accept it, and inspect the weapon.'' ''Dinh moves to the side to grab his helmet. The Player Spartan's gaze focuses towards the sunset, before Dinh wanders back in front of them.'' Dinh stares at his AI chip once again. Dinh begins to walk off, but turns to face the Player's Spartan. Dinh walks off, and the Player's Spartan turns to see the sun disappear behind the distant mountains.
 * Spartan Hieu Dinh: "He found memories I've never told anyone. Details I wish I forgot."
 * Spartan Sigrid Eklund: "Dinh. That desert was a long time ago. There's nothing you could have done to save them."
 * Dinh: "'Death for you. And triumph for me.' What the hell does that mean?"
 * Eklund: "That I am your friend. And that the thing in your head was not."
 * Eklund: "Ah, ja. Here's the one I told you about. The newest member of our pack. Play nice. This wolf saved your life."
 * Dinh: "You tell Agryna not to worry. My head's as good as it ever was!
 * Eklund: "Maybe that's what she's worried about."
 * Dinh: "You shove one Banished AI into your neural matrix, and everyone panics!. Look. I'm not great with 'thank you.' So, here."
 * Dinh: "It kicks. But its never let me down."
 * Dinh: "You know, I cycled through here for training too. This place is old, just like me."
 * Dinh: "Iratus didn't care about me... He only cared where I might go."
 * Dinh: "You get good with that, then come find me. This place? It has memories too."

''The scene cuts to a War Games session taking place on Live Fire, with the camera slowly panning through the central underground hallway as Spartans run by out of focus. The camera approaches the 'BLDG-09' door in the center of the hallway, as a stray M9 fragmentation grenade lands in front of it. The grenade detonates, and the blast damage scrapes much of the paint off, revealing that the paint was covering an Office of Naval Intelligence seal.''
