Capture the flag and surprise ending

That evening, after dinner, the excitement was at its peak. It was time to capture the flag. When the plates were cleared, the foghorn sounded and we all stood up at our tables.
Campers shouted and cheered as Annabeth and two of her siblings ran into the lodge carrying a silk banner. It was about three meters long, a sparkling gray and bore a painting of a barn owl, above an olive tree. On the other side of the pavilion, Clarisse and her pals came running in with another identical banner, but in a garish red, painted with a bloody spear and a boar's head. I turned to Luke and shouted above the noise:

"Those are the flags?"

" Yeah."

" Ares and Athena always lead the teams?" Asked Percy, who was standing next to me.

"Not always," Luke replied. "But often."

"So, if another cabin captures one, what do you do, repaint the flag?"

He smiled. "You'll see. First, we have to get one."

"'Whose side are we on?" asked Percy.

He gave her a sly look, as if he knew something he 'd never known. The scar on his face made him look almost diabolical in the torchlight.

"We've made a temporary alliance with Athena. Tonight, we get the flag from Ares. And you're going to help."

The teams were announced. Athena had formed an alliance with Apollo and Hermes, the two largest cabins. Apparently, privileges had been exchanged-shower times, chore schedules, the best slots for activities, in order to win to get their support Ares had allied himself with all the others: Dionysus, Demeter, Aphrodite and Hephaestus. From what I'd seen, the children of Dionysus were good athletes, but there were only two of them. The children of Demeter had the advantage when it came to nature and outdoor activities, but they weren't very aggressive. Aphrodite's sons and daughters didn't worry me too much. Most of the time, they stayed away from all activities, looking at their reflections in the lake, combing their hair and chatting. The Hephaestus children weren't pretty, and there were only four of them, but they were big and strong from working in the metal workshop all day. They could be a problem. That left the Ares cabin: a dozen of the biggest, ugliest, fattest, biggest, ugliest, baddest guys on Long Island, or any planet.
Chiron struck the marble with his hoof.

"Heroes!" he announced. "You know the rules. The creek is the boundary line. The entire forest is fair game. All magic items are allowed. The banner must be prominently displayed, and have no more than two guards. Prisoners may be disarmed, but may not be bound or gagged. No killing or maiming is allowed. I will serve as referee and battlefield medic. Arm yourselves!" Chiron spread his hands and the tables were suddenly covered with equipment: helmets, bronze swords, spears, metal-covered oxhide shields.

"Whoa," said Percy. " We're really supposed to use this?"

Luke looked at him like I was crazy.

"Unless you want to get skewered by your friends in cabin five. Here, Chiron thought it'd be okay, you'll be on border patrol." He handed her an array of combat gear.

"And you Kassandra Chiron told us you were already armed." he said pointing to my father's ring. "And you're coming with me."

I picked up a shield the size of a basketball backboard. It was adorned with a caduceus in the middle and it must have weighed about Three Thousand Pounds... yeah that sounded pretty heavy to me. My helmet, like all those of my team, was topped by a blue plume. Ares and their allies had red plumes.
"Blue team, forward!" Annabeth shouted.
Percy stopped next to her to ask her something, I was at Luke's side.

"So what do I do?" I asked.

"Stay close to me, you'll see everything will be fine." he said, adding a sort of half-malicious, half-diabolical smile behind his sentence almost to say "I'm telling you this, but everything's going to go to hell tonight". I preferred not to say anything more.
