- "What can we do to keep the Covenant out?"

- "We don't have any choice, doctor."
- "If we can't move the Composer, we have to make sure the Didact can't either."
- "I'm sorry, doctor. Keep routing your people to the evac centers. Once we take care of the Composer, you won't have much time."

- "Cortana, see if you can raise Tillson. Get me a status on the rest of the station."

- "How...?"
- "So how do we get out of here?"
- "... what?"

- "I am not leaving you here!"
- "It was my job to take care of you."

- “I do not remember my name. I do not remember my family. I do not remember my home. But I can remember the game. We played it everyday. And I never lost. The game… it's the only thing I can remember about the life I had before I met Doctor Halsey. Since then, I have experienced a lifetime of combat. Through thirty years of war against alien aggressors… I have always known my fate. I knew someday I would die in battle. But now that it is here… now that it is time to die… I find I am not ready.” — Internal monologue, while having head crushed by the Ur-Didact
