Feeding the Belly of the Beast
The Master Chief and a group of marines are deep inside a Covenant cruiser. A door opens, and they enter the cruiser's detention area.
Cortana: This looks like the ship's brig. The cereal signal is strong. And we might find the captain, too.
Marine (in holding cell): Chief! We're starving, let us out, man!
Captain Keyes: (in adjacent holding cell) Stow the bellyaching, soldier. Remember, you're a leatherneck.
Master Chief: So that's what they're made of.
