While the Blue Team was infiltrating through the Docking Bay, Thomas was laying on the ground. John said, "You shall allow us to continue what we started by taking the UNSC Life of Eternity from you all. And if you don't allow us to get away safely, we will kill the rest of the crew."

Bullets were flying everywhere in the back of the ship and then Mark said, "Sir, we have intruders."

John said, "Take care of them already."

Mark said, "We're trying, but it's Master Chief."

Thomas smiled and asked himself, "Who the hell is Master Chief?"

A voice appeared in his head and answered, "Master Chief is a Spartan from the SPARTAN-II Project. And one of a very few remaining SPARTAN-II's left."

Thomas heard that and asked the voice, "Who are you?"

The voice answered, "An ally. Just like Master Chief and the rest of Blue Team."

Thomas sighed in his head and asked her, "What do you want from me?"

The voice answered, "Well, the Insurrectionists took over your ship in just seconds. They were about to kill the members of Fireteam Mockingbird. Which you stopped from happening. That is what brought the enemy to arise."

Thomas said to her, "Yeah, I kinda figured that when I got shot in the back of my head where the metal plate was."

The voice said, "Alright, I'll tell you my name. I'm Cortana and I used to be an ally of the UNSC. Also, I was an AI that used to work with Master Chief, a.k.a. John-117."

Thomas heard that and asked her, "What did you mean by used to be an ally of the UNSC?"

She answered, "I tried killing everyone in the galaxy."

Thomas smiled and then the people of his crew looked at him and then Thomas asked her, "What do you want me to do exactly?"

Cortana answered, "I have a feeling that you probably want to kill the man that shot you, correct?"

Thomas answered her, "Hell yeah. I want to tear him apart."

Cortana said, "Well now, is that how you've always been?"

Thomas answered her, "Yes. I was actually the most insane soldier on the UNSC Bark."

Cortana said, "I see. Oh yeah, you were the one that went from Airman Basic to Vice Admiral."

Thomas said to her, "Yep. That would be me."

While she was talking to him through his mind, John asked, "Why is Master Chief here, I wonder? I know that this is a new ship that is controlled by this dumb piece of shit down here. But he's dead. Kill everyone. I don't care if he's a Spartan or not. Plus, Thomas Kramer is going to regret this."

Lasky heard that and said, "Back off Blue Team."

John-117 heard that and said, "But..."

Lasky whispered, "Just play along. But don't actually leave."

They smiled and said, "Understood."

John smiled and Lasky said, "They are leaving the ship, Bennett. Now let the rest of the people live."

John said, "Good job, Lasky. You are working up a good sweat."

Lieutenant Jay Grant said, "Sir, we have a massive hole in the left engine."

John said, "I guess that we can't fly this ship anymore."

Jay said, "No, actually we could still fly it. But not as fast as before."

John asked, "How did it get destroyed anyway?"

Jay answered, "Unknown. I'm looking into it right now."

John heard that and said, "Put it on the main screen."

Thomas heard that and said to her, "Tell me what they are looking at."

Cortana said, "Yessir."

Thomas smiled and then they put the camera's of the Engine Room up and then looked back on it and then saw a light appear from 10 feet away from the engine and John said, "Someone shot the engine with a shotgun."

Gunnery Sergeant Liam Vortex said, "That wasn't a shotgun, sir."

John heard that and asked, "What was it, Vortex?"

Liam answered, "That was an unknown weapon that acted like a shotgun."

Cortana said, "It seems that they are looking into the damage done to one of the engines."

Thomas asked her, "What do you think done it?"

Cortana answered, "An unknown threat maybe. Somehow, someone brought a deadly weapon capable of putting a hole into the engine."

Thomas sighed in his head and asked her, "Is it possible for an alien to transform into a human body? And use camouflage to infiltrate the ship?"

Cortana answered, "Yes it is. But it's very rare for that to happen."

Thomas asked her, "How rare?"

Cortana answered, "Very rare."

Thomas looked at the soldier in front of him and moved his lips without words coming out saying, "What do you think the enemy is?"

The soldier moved her lips the same way as him and answered, "Unknown. Sorry sir."

Thomas nodded and then Liam said, "Everything is invisible. We can't see a thing. And can't see who did it. It definitely wasn't the Spartans. That's for damn sure."

John said, "Alright, an unknown threat is aboard this ship. Find it and kill it."

Cortana appeared in front of him and said, "Stop asking people for help and ask yourself what you should do. He's got his back toward you. But then there are other Insurrectionists in the same room. It's really risky."

Thomas looked at her and asked, "Why are you trying to help me?"

Cortana answered, "You survived the crash from the UNSC Bark. The best ship at the time. But it was tampered with by the Insurrectionists of your time. You know about the Insurrectionists. You can fight them just like you did back then."

Thomas sighed and said to her, "You are asking me to go all out and put the mask on."

Cortana said, "Exactly. Be your old self. The one that everyone feared. And the one that knew his repairs."

Thomas said to her, "Alright. Tell everyone that is in here to be careful. I'm about to go berserk."

Cortana smiled and then said, "Do it."
