Leave No Spartan Behind[]

  • Exuberant Witness: The Gateway. I tried to warn them, and... well, here we are.
  • Buck: Once Chief knows the destruction Cortana's caused, what do you think he'll do?
  • Tanaka: The man'll do the right thing. Always has.
  • Locke: Let's find him.
  • Exuberant Witness: Oh, this is interesting. Or maybe this is terrible.
  • Locke: Exuberant? What is it?
  • Exuberant Witness: Cortana has activated a Cryptum.
  • Vale: A what?

Exuberant gestures towards the hologram of the Cryptum in the center.

  • Exuberant Witness: This is a Cryptum. It is a device for extended forced meditation. Cortana has placed the other Humans and is preparing it for Slipspace travel.
  • Locke: She's planning to take Blue Team with her. Where is the Cryptum from here?
  • Exuberant Witness: Not far. Right this way.
