Chapter 4: salvation
The small swarm of ATV's went into the base and reported to Kelly all that had happened. She was slightly stunned that the chief would do something like that, but then realized it was his character, and he had fought the flood many times before and much more effectively than they had. She gave command to Chief Alan Gonzolaz and took off to help the master chief, equipped with the standard pistol, a rocket launcher, a laser rifle adapted from the covenant plasma rifle, and some more ammunition for the shotgun and assault rifle. She grabbed a warthog, shoved all of the extra ammunition she could into the back seats, and screamed after the chief to give any help she could.
The flood just kept coming, thousands more than on halo. The chief was glad he had taken the marines ammunition, he was almost out as it was, when Kelly finally got there, she jumped out and fired a single rocket toward the middle of the flood, killing most of them. Master Chief was relieved to see Kelly, and the extra ammunition, but he was worried. He had never seen so many flood at one time, even when trying to destroy the ringworld halo. He feared that they would be overwhelmed and destroyed, or worse, made into terrible super flood, almost invincible with their shields and augmented bodies.
They nodded to each other and opened a private COM line; they were safe under the foot thick lead of the tunnels.
"Thought you might need some help Chief," said Kelly, "I brought some extra ammo, and a rocket launcher, as you saw."
"Thanks Kelly, you don't know how much I needed the ammo and help" the chief responded, as he ejected his final clip from the assault rifle and put his last round in the shotgun, "but you need to get back to your base, it needs a defense if I fail."
"I have left a trusted commander in charge, he will not fall easily, I am staying to help you." She said forcefully.
They walked deeper into the tunnel together, ready for anything that could come.

Sorry for such a short chapter it just seemed like a good place to stop. And just so you know I don't plan on this being a romance, I just thought it would be cool to have Kelly make a return.
