ODST RED ALERT part 5

Irish pried the elevator door open so they could all get out of the shaft.
"The power still isn't on in this sector." Irish said looking at the closed security door. "Thea, see if you can do something about this."
"I'll see what I can do." He said as he briskly walked off towards a nearby terminal.
"This is 12 levels from where Delta fell." Assrak said. "You think that he could be on this level?"
"This is the only level that has any significant life readings on it." Irish said. "If he is still alive, he'll be here."
"Besides, our objective is to find the Professor." Pasagoa said. "If Delta's still alive he'll find a way off this thing, he IS an ODST after all."
"Delta is still a priority." Irish said. "We can collect the Professor's data if he's dead. Delta's skills can't be "collected."
"You never told us where you found him sir." Assrak said.
Irish looked at Thea. "Are you going to be long Corporal?"
"Most likely." Thea said. "There seems to be something blocking the power flow to the lower sectors. I'll see if I can't dislodge it."
"Well, since we have time," Irish said a he took off his helmet, "I guess I should tell you about the Lieutenant." Irish's face was of a some what round build. His nose slightly bent at the bridge, suggesting a broken nose. His eye's weren't visible in the lower level light but it was a plain as day how many scars he had on his face, all scattered around his features, under his eye, across his lips and a massive scar raging from the top of his forehead to the bottom of his chin. "I found him during the last battle for Darla. He was a Corporal back then, in the UNSC. His squad had been all but wiped out. I was serving with his father, Lieutenant Nightstalker, back when I was a Sergeant. Our mission was to find missing ONI officers and get them to the Infinity. When he saw Delta and his squad being overwhelmed, he ordered our Pelican to lower and extract them. The pilot said that he already had his orders and landing wasn't part of it. He would take no as an answer. He opened the rear hatch and rappelled down to the ground. He was an ONI officer himself so the Pelican had to pick him up. I was the first person off the Pelican to support him. He was barking orders at the UNSC soldiers to board the Pelican. Delta was the only person who disobeyed that order. The Pelican was soon full and had to take off, leaving me, Delta, a few other ODSTs and the Lieutenant. We had to wait for another Pelican that was on-route with other evacuees. I was surprised to see how many Covenant died by Delta's hands. He was amazing. You all know what he's in a battle, he's near unstoppable.  The Covenant just kept on coming, growing bigger and bigger in number but we still didn't take a hit. We were afraid that, because of the amount of Covenant around the L.Z, the Pelican would have to divert to a different L.Z or even leave us and evacuate the civilians. Thankfully, the pilot tried to pick us up but the fire coming from the enemy positions forced him to land further behind us. We had 2 options. Stay and fight to the death, or make a break for the Pelican and get to the Infinity. The Lieutenant said that he would stay to buy us time. Delta was very stubborn back then…"
"He still is sir!" Pasagoa said jokingly.
"You've got a point. As I was saying, he was determined to stay with him. I don't know what he said but the Lieutenant was able to convince him to go. He handed him something before we left. We bolted for the Pelican with the constant fear that the Covenant where right behind us. Finally we reached the Pelican and took off. We passed over the trenches to find that the Lieutenant was still alive. He was using an energy sword to cut away at the Covenant forces. He fell to the blade of, what looked like, the current Arbiter. But not before dealing the killing blow to the Arbiter himself. After that, Delta became an ODST and joined my squad."
"That still doesn't explain why he has such good skills." Assrak said.
"The reason why he fights like that is…" Irish paused.
"Is what?" Thea asked worriedly.
"The reason why he fights like that is because…he's a Shadow Soldier. They were the UNSC's secret and main force of Supper Soldiers before the SPARTAN program was initiated." He stood to replace his helmet. "He is the last of the Shadow Soldier program."
