Halo: Combat Evolved
The Pillar of Autumn
- "Captain Keyes." - To Jacob Keyes, upon entering the bridge, marking his first line in the Halo Trilogy and series.
- "No thanks to your driving, yes." - Response to Cortana, who asked him if he slept well in his Cryo-chamber, referencing what Dr. Halsey said in a previous mission.
- "Don't get any funny ideas." - To Cortana, after putting her data crystal chip in his helmet.
- "Punch it." - To the pilot of a Bumblebee escape pod as he step into the Bumblebee.
- "We'll be fine." - In the Bumblebee as it enters Alpha Halo's atmosphere, when Cortana suggested taking a seat.
Assault on the Control Room
- "You all right?"
- "Let's stay focused. Halo... how do we use it against the Covenant?" - After he uploaded Cortana into Halo's Core.
- "Slow down. You're losing me."
- "Something buried? Where?"
- "I don't understan-"
Two Betrayals
- "Hold on now, he's a friend."
- "Yes... Activate Halo's defenses, and destroy the Flood, which is why we brought the Index to the Control Center." - When Cortana asked him if he knew what he almost did.
- "Enough! The Flood is spreading. If we activate Halo's defenses, we can wipe them out."
- "Is it true?"
- "That's not going to happen." - When 343 Guilty Spark claims he will forcefully take Cortana away from the Chief.
- "Let's find a ride and get to the Captain."
- "You have a better idea?"
- "Something tells me I'm not gonna like this." - When Cortana proposes a faster way of transportation to find Captain Jacob Keyes — teleportation.
The Maw
- "We'll make it." - To Cortana, who panics about their flight on a Banshee to the Template:UNSCship.
- "How much firepower would you need to crack one of the engine's shields?"
- "Here we go." - Calmly as he starts the Longsword to leave the self-detonating Template:UNSCship.
- "Did anyone else make it?" - To Cortana, when they escaped from Halo's destruction on a Longsword.
- "No. I think we're just getting started." - When Cortana said that "Halo is finished".

Cairo Station
- "You told me there wouldn't be any cameras." - To Sergeant Major Avery Junior Johnson.
- "I need a weapon." - To Johnson, after being given the order to protect the Cairo Station.
- "Sir, permission to leave the station" - To Lord Hood, asking permission to leave Cairo Station.
- "To give the Covenant back their bomb." - To Lord Hood, explaining to him the reason for leaving Cairo Station.
- "I won't." - Confidently to Cortana, who gives him the idea of him missing the the Covenant Assault Carrier.
Gravemind
- "Relax. I'd rather not piss this thing off." - To the Arbiter Thel 'Vadamee, who struggles in the Gravemind's tentacles.
- "This thing is right. Halo is a weapon. Your Prophets are making a big mistake." - To the Arbiter, after the Gravemind attempts to convince 'Vadam the true use of Halo.
- "Boo..." - To the Grunt while Prophet of Truth are not noticing his presence yet after being teleported into High Charity by the Gravemind.
High Charity
- "Your pal. Where's he going?" - To the Prophet of Mercy, who is dying from a Flood Infection Form.
- "That Brute has the Index. And Miranda and Johnson. He can activate the ring." - Expressing his concerns to Cortana if he pursuits Truth (instead of chasing Tartarus) to the Forerunner Dreadnought in High Charity.
- "After I'm through with Truth—" - Making a promise to Cortana as the Dreadnought leave High Charity, cut mid-sentence by Cortana.
The Great Journey
Halo: Uprising

The Storm
- "Worse." - After the Arbiter asked if more Brutes arrived.
Floodgate
- "Wait, leave her alone" - To 343 Guilty Spark when trying to defend Cortana.
- "On Halo, you tried to kill Cortana. You tried to kill me." - To 343 Guilty Spark
- "It's just a message."
- "I'll find Cortana's solution. And I'll bring it back."
The Covenant
- "Not close enough." - In the Ark's Citadel, answering Commander Keyes' question on how close is he to Truth.

- "Not lucky enough, we lost two Spartans today: Solomon and Arthur. And that Elite we encountered... he was strong. I have to be stronger." - To Halsey when she tells John how lucky he is.
Halo: Reach
Firefight Voice
Halo 4
Dawn
- "Ready to get back to work?"
- "How long was I out?"
- "I thought we had a truce with the Covenant."
- "Maybe they haven't recognized us."
- "These Covenant seem more fanatical than the ones we fought before."
- "The Covenant weren't the one's scanning us."
Requiem
- "Something was wrong before we left the Dawn."
- "If we could just get back to Earth, and find Halsey, she could fix this."
- "It sounds like the Covenant were here looking for something."
- "They've been waiting outside the planet for three years?"
- "Asking's not my strong suit."
- "Requiem. At least we know where we are now."
- "That can't be right. Scan again."
- "You mean the planet's hollow?"
- "What do you know about Infinity?"
- "Humanity... That's got to be Infinity. Can you get us to those coordinates?"
Forerunner
- "What were those things?"
- "The beacon was pulled into Requiem with us. If they try to follow it..."
- "I'll handle them; you just find us that control node."
- "How soon 'til Infinity hits the gravity well?"
- "We don't have time!"
- "Infinity! This is Sierra-117 of the UNSC Forward Unto Dawn. Do you copy?"
- "Same place we are."
Infinity
- "Something tells me that's only because the Didact wanted it that way."
- "This is Sierra-117 of the UNSC Forward Unto Dawn. We're on station, ready to assist."
- "Light up their friend-or-foe tags; we're gonna need something to zero in on."
- "That scan's the same one we saw on the Dawn."
- "They must not have received his distress call."
- "Lasky?"
- "Then Lasky's still out there somewhere."
- "On occasion. I'll send out an all-clear once the area's secured."
- "Cortana? How close are we?"
- "It's alright..."
- "Covenant?"
- "Yes, sir."
- "Sir, what's our status?"
- "Can we break the connection?"
- "Go, Commander."
- "Other installations?"
- "Captain?"
- "Sir, Infinity drove the Didact back. He's vulnerable!"
Reclaimer
- "Captain, what's Force Recon's assessment of the terrain?"
- "We'll make it work."
- "On our way."
- "I'll get to them and retrieve the designator."
- "Sit tight, marine. We'll get you out of here."
- "It's OK."
- "You know I won't let that happen."
- "Sir, I can move faster alone."
- "This could be a trap."
- "Cortana? Cortana!"
- "Who are you?" - John-117 to the Librarian.
- "The Prometheans... they're human."
- "Planning for what?"
- "Can I defeat the Didact without it?"
- "It's a long story, but I know what the Didact's after."
- "Sierra One One Seven to Infinity, what's our status?"
- "Does Infinity have a shot on the gravity well?"
- "Sir, we've seen what the Didact is capable of. If we let him leave this world, humanity will be at risk."
- "With all due respect Sir, I know what I saw."
- "The Didact has to be stopped. If you won't do that... I will."
- "No, Sir."
- "Get word to Earth that trouble is coming. Cortana and I will do what we can back here."
Shutdown
- "Infinity's tracked the Didact's vessel to a docking structure southeast of here. We'll jump ship as Infinity exits the roof."
- "Cortana, where's this coming from?"
- "He's there. Keep trying."
- "Cortana, are you hearing him?"
- "What are you doing?"
- "His ship's online! They're leaving!"
- "Track those Liches. We can go across them to get to the Didact's ship."
Composer
- "This is UNSC Master Chief to base. Do you read?"
- "They're after a Forerunner artifact you took from a Halo ring."
- "Doctor, I need you to protect that artifact until we arrived. Send whatever-"
- "Doctor, listen to me. You have to issue the order to evacuate the station."
- "Send me your coordinates. I'll see what I can do about clearing an evac route on my way to you."
- "What can we do to keep the Covenant out?"
- "The device you recovered was a Forerunner weapon. The commander of that ship wants it back."
- "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."
- "Doctor Tillson, the Composer's location's been compromised. You've got to get the nuke down here!"
- "Ready or not, I need it now!"
- "Cortana, see if you can raise Tillson. Get me a status on the rest of the station."
- "Cortana, I need that info! (sigh) Look... don't think about the Didact. Don't think about the Composer. Only focus on finding me Tillson."
- "Didact's taken the Composer. Get these people to the evac centers!"
- "Cortana. It's not over. Not yet."
Midnight
- "The Didact's got the Composer. We're in a Broadsword carrying a HAVOK-grade payload, on approach to deliver it."
- "Commander, direct all your ships to the Composer."
- "Infinity, the Didact just closed off our entrance to the Composer."
- "Clean hit. We're proceeding to insertion."
- "Plan B."
- "We'll have to deploy the warhead manually. How and where?"
- "Keep scanning for the Composer. We'll figure it out along the way."
- "Cortana? Cortana, do you read? Cortana, come in."
- "How...?"
- "So how do we get out of here?"
- "... what?"
- "No. That's not-! We go together."
- "I am not leaving you here!"
- "It was my job to take care of you."
- "Cortana- please..."
- "Wait."
Epilogue
- "Our duty as soldiers, is to protect Humanity, whatever the cost."

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
