Fade in to Catherine Halsey, sitting in her cell aboard Infinity. Roland appears before her.

Roland: "Can I ask you a question, doc? What were you hoping to achieve with you little subterfuge? I mean, Captain Lasky put a lot of faith in you."

Halsey: "Yes, his hospitality speaks wonders."

Roland: "C'mon on doc. What is keeping secrets every really gained you?"

Catherine Halsey: "What is hidden can be useful."

Roland: "Such as??"

Catherine Halsey: "Such as the phrase undid-iridium."

Roland: "Un-un-did-un-un-did-undid-"

Roland's hologram rapidly flickers, then settles. The AI looks up at Halsey with an expression of blank obedience.

Roland: "UNSC A.I. overiding instructions active, Doctor Catherine Halsey."

Halsey: "Roland. tell the guards outside that captain Lasky has requested my presence in his ready room and block all further communications."

Roland: "Yes."

Two Marines open the cell door, and gesture for Halsey to exit.

Marine: "Captain asked to see you, doctor."

Halsey steps out of the cell and is escorted down the hall with them. Fade to black.

Fade in to Lasky's office, where Halsey was previously interrogated. Title in

HALO: INFINITY

. Halsey is escorted inside.

Marine: "Have a seat, doctor."

Roland: "Thank you, gentlemen. You may go."

The two Marines look at each other as if suspicious of the order, but agree and step out. Halsey walks to the room's large screen.

Halsey: "Roland, give me full access to this terminal."

Roland: "Yes, Doctor Catherine Halsey."

The screen fills with images of Jul 'Mdama.

Halsey: "The Didact's Hand. If people would just share things with me I can solve all the world's problems. Send everything the UNSC has on the Librarian to my datapad."

Roland: "Yes, Doctor Catherine Halsey."

Halsey examines the sent info on her data pad.

Halsey: "This is all my own research! I need new information. Anything that has been kept from me."

Roland: "Only one datapoint exists that is not your own research. Debriefing of Master Chief Petty Officer SPARTAN-117 post-New Phoenix Incident."

Halsey reacts with shock.

Halsey: "John? I... Roland, prep a Pelican for immediate launch. And patch this terminal into the comms system's infiltrated by artifact."

Roland regains control of himself.

Roland: "Doc!!! Whatever you did to me- aaugh..."

Roland calms down and resumes obedience.

Roland: "Yes, Doctor Catherine Halsey."

Cut to Mdama's terminal. The Sangheili observes Halsey appearing in it.

Halsey: "Jul 'Mdama."

'Mdama: (Sangheili) "You... are Catherine Halsey."

Halsey: "I have played your game quite long enough and we are both out of time. In our previous conversation you mentioned 'assistance'."

'Mdama: "How do you know...?"

Halsey: "Who but the Didact's Hand could offer me a Promethean soul?"

'Mdama: "What is it that you want?"

Halsey: "What we both want Jul: Librarian. A powerful name for me as well as you. Librarian is very fond of humans. Did you know that?"

Behind her, Roland splits into two avatars. A flickering weak red Roland is pushed away by a strong green Roland, then is grabbed and swallowed up again. Roland regains control of himself.

Roland: "That was a dirty trick, doc! My turn now!"

Roland opens the office's door. The two Marines return inside, guns raised.

Marine: "Stay right where you are doctor!"

Cut to Captain Lasky, escorted by Marines to re-meet Dr. Halsey.

Lasky: "Doctor Halsey, I've underestimated you long enough. A cryo-tube should hold you unt-"

Halsey walks up to Lasky and slaps him.

Halsey: "John's alive. He was here on this ship. Nobody told me he was alive."

Alarms in the hallway go off. Cut to Infinity's hangar. Marines open fire on Promethean Knights that are phasing aboard Infinity.

Marine: "They're everywhere!"

The Marines return fire, but some are shot down. Sarah Palmer leads the defense with a pair of M6H pistols.

Palmer: "Hold the line!! Nothing gets past!!"

Lasky (COM): "Commander Palmer report!"

Palmer: "Kind of busy, captain!"

More and more Prometheans rush into the attack. Palmer picks them off with her pistol. A Promethean Knight appears behind Palmer.

Palmer: "Knock your face into the artifact."

She punches it and and kills with a headshot. Once it's dead she returns to fighting those in front of her.

Palmer (COM): "Don't worry, we'll keep them contained in the hangar."

Cut back to Lasky and Halsey in the hallway.

Lasky: "Too late, they're here too!"

Prometheans fire down the hallway. A Marine is shot down by one, knocking down Halsey.

Lasky: "Halsey!! Come on, doctor!!"

Lasky leaps to defend her with a M45 Shotgun. He kicks the Knight standing above her, and blasts it in the chest. Once it's dead, Lasky pulls Halsey to safety. Another Marine shot down as they pass. The two hide behind a corner and Lasky activates the ship's public comm.

Lasky: "Captain Lasky to all hands, battlestations!! This is not a drill!"

Halsey: "Lasky!!"

Promethean Knights flare their skulls at Lasky and Halsey. Cut to black.

Trivia

In the opening cinematic, a Marine yells, "They're everywhere!"; this is a notorious line spoken by the BoBs in the original Marathon. However, Marathon is owned by Bungie, not 343 Industries, so it is more likely a coincidence rather than a deliberate reference.
