Enter the Bridge

*As the Spartan approached, the doors leading to the bridge opened, the two security guards step to the sides, letting him through*

Guard 1: *to Guard 2* Look at that, that's an original Spartan.

Guard 2: Doesn't look much different than a Four.

Guard 1: Well that armor Fours wear I heard make them as good as the originals.

Guard 2: Speaking of that, have you heard those rumors in the mess about a fifth series?

Guard 1: Fives? No way, they practically just started the Fours.
