The rest of the week went calm. Danny was slowly joining daily routine of the Camp.

Each morning he taught Percy Ancient Greek. Thankfully, this guy was catching on pretty fast. For someone with dislexia that's for sure. Then, he did outdoor activities.

Sword fighting? He was damn good. The fact that Danny had a lot of fighting experience, besides training, gave him an advantage. So he beated the shit out of everyone. Also he MIGHT have cheated a bit, but, hey, it's either sand in enemy's face or sword in your gut. Some offered him to fight against Luke, but he just said: "All in due time"

Archery? That's when things went south. Danny and bows are now sworn enemies. Each time he tried everyone hurried to get out of the way the arrow can possibly and impossibly go. It's not like it should bother him, he has a literal 'death glare'. "You sure aren't Appolo's kid," one of the others said and hit the bullseye without even looking.

Spears were better, but still not as good as sword.

Speaking of, Danny started working on his own sword. He kept production process in secret, so it will be a surprise for his enemies. Especially one feature he added.

The senior campers and counselors were watching him, trying to decide who his parent was, but they weren't having an easy time of it. Danny wasn't as hot headed as the Ares kids, or as good at archery as the Apollo kids. Some thought about Hephaestus, since he did well with smithing, some about Athena. Danny was sneaky, creating a theory about him being the son of Hermes. He didn't steal a single thing, though, so this idea wasn't very popular.

As the time went, Percy seemed more gloomy, so Danny decided to talk with him.

"Hey, Percy," he said, with a smile.

"Hey Danny," Percy responded, staring on the fire.

"Waiting, huh?" Danny sat nearby. Percy sighed.

"I start to understand Luke's bitterness. So okay, maybe gods have important things to do. But can't they call once in a while, or thunder, or something? Dionysus can make Diet Coke appear out of thin air. Why couldn't my dad, whoever he is, make a phone appear?"

"Well, I doubt he is the God of phones"

"Why are you so calm? It's not like everything around here is normal," he gestured to the satyr, who was chewing tin can.

"I agree, you don't see things like that daily, but...I have seen too many weird things before to care. As for parents," Danny shrugged, "even if I would never be claimed, it's not the reason not to enjoy my life. I'm sure your father will claim you when the time comes. Alright... I want to teach you something"

Later Danny and Percy were standing in front of each other, swords in their hands. Some curious kids were standing near.

"Okay, Percy. I watched others' training and noticed that this is not what you need"

"What do you mean?"

"Not to offend, but you aren't strong," some snickers in the crowd, "so we will train differently. Loose your elbows so you can better react..."

"Wouldn't it let enemy too close?" Percy asked. Danny grinned.

"That's the point"

He attacked. Of course, Danny was easy on him, but still. He showed Percy thrusts and parries and shield blocks the hard way. With every swipe, Percy got a little more battered. "Keep your guard up, Percy," he'd say, then whap him in the ribs with the flat of his blade. "No, not that far up!" Whap! "Lunge!" Whap! "Now, back!" Whap!

By the time Danny called a break, Percy was soaked in sweat. To everyone's surprise, Phantom took a bottle of cold water and spilled the contents on Percy's head.

"What are you doing?" He exclaimed.

"Better?" Danny asked.

Instantly, Percy did feel better. Strength surged back into his arms. The sword didn't feel so awkward.

"What the..."

"Let's continue, shall we?" Phantom said with a grin.

-Lateer-

At last, it was time for capture the flag.

Campers yelled and cheered as Annabeth and two of her siblings ran into the pavilion carrying a silk banner. It was about ten feet long, glistening gray, with a painting of a barn owl above an olive tree. From the opposite side of the pavilion, Clarisse and her buddies ran in with another banner, of identical size, but gaudy red, painted with a bloody spear and a boar's head.

Danny turned to Luke and yelled over the noise, "Those are the flags?"

"Yeah"

"Ares and Athena always lead the teams?"

"Not always," he said. "But often"

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

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

The teams were announced. Athena had made an alliance with Apollo and Hermes, the two biggest cabins. Apparently, privileges had been traded: shower times, chore schedules, the best slots for activities, in order to win support.

Ares had allied themselves with everybody else: Dionysus, Demeter, Aphrodite, and Hephaestus. From what Danny'd seen, Dionysus's kids were actually good athletes, but there were only two of them. Demeter's kids had the edge with nature skills and outdoor stuff but they weren't very aggressive. Aphrodite's sons and daughters, well...they mostly sat out every activity and checked their reflections in the lake and did their hair and gossiped. Hephaestus's kids weren't pretty, and there were only four of them, but they were big and burly from working in the metal shop all day. They might be a problem. That, of course, left Ares's cabin: a dozen of the biggest, ugliest, meanest kids on Long Island, or anywhere else on the planet.

Chiron hammered his hoof on the marble.

"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!"

He spread his hands, and the tables were suddenly covered with equipment: helmets, bronze swords, spears, oxhide shields coated in metal. Danny just kept his hands in pockets.

"Aren't you going to take anything?" Luke asked. Danny only smirked.

Annabeth yelled, "Blue team, forward!"

People cheered and shook their swords and followed her down the path to the south woods. The red team yelled taunts at us as they headed off toward the north. Danny took sunglasses on.

"Eh, why are you wearing sunglasses at night?" Percy asked. He actually looked stupid in his unfitting armor. Danny looked at him.

"Hello! My eyes are a freaking lighthouse. I don't want to be noticed, plus I see everything perfectly"

It was a warm, sticky night. The woods were dark, with fireflies popping in and out of view. Annabeth stationed Percy next to a little creek that gurgled over some rocks, then she and the rest of the team scattered into the trees.

Standing there alone, with his big blue-feathered helmet and his huge shield, he felt like an idiot. But he wasn't alone. Danny was sitting on the tree, invisible. Most possibly, Annabeth's plan was to lure Clarisse and her buds, using Percy as bait. Dirty, but ends justify the means. He heard a low canine growl, somewhere close by. Danny looked around, but sounds abruptly stopped.

On the other side of the creek, the underbrush exploded. Five Ares warriors came yelling and screaming out of the dark.

"Cream the punk!" Clarisse screamed.

Her ugly pig eyes glared through the slits of her helmet. She brandished a five-foot-long spear, its barbed metal tip flickering with red light. Her siblings had only the standard-issue bronze swords.

They charged across the stream. There was no help in Percy's sight. Danny walked calmly to them, still invisible. He needs to play for time.

Percy managed to sidestep the first kid's swing, but these guys were not as stupid the Minotaur. They surrounded him, and Clarisse thrust at him with her spear.

Electricity. Her stupid spear was electric. Percy fell back.

Another Ares guy slammed him in the chest with the butt of his sword and he hit the dirt.

They could've kicked Percy into jelly, but they were too busy laughing.

"Give him a haircut," Clarisse said. "Grab his hair"

"If it were they who made yours than I can only feel pity for you," they turned around and saw Danny, who was grinning innocently.

"You!" She immediately and tried to stab him with her spear, but it was deflected immediately.

Everyone stared at the sword, which Danny took literally out of nowhere. It looked unusual. The sword had black handle, with green gem on the bottom. But the most interesting thing was blade. It looked transparent, as if made from glass. And yet, it was strong enough to block hits. Clarisse kept coming, the point of her spear crackling with energy. After some time, Phantom got bored. As soon as she thrust, Danny striked with his sword, and he snapped the spear like a twig.

"Ah!" she screamed. "You idiot! You corpse-breath worm!"

She probably would've said worse, but he smacked her between the eyes with his sword-butt and sent her stumbling backward out of the creek. Danny looked at the side and saw Percy standing in the water, with enemies lying nearby.

"Nice job, Percy!" He said, smiling.

Then they heard yelling, elated screams, and they saw Luke racing toward the boundary line with the red team's banner lifted high. He was flanked by a couple of Hermes guys covering his retreat, and a few Apollos behind them, fighting off the Hephaestus kids. The Ares folks got up, and Clarisse muttered a dazed curse.

"A trick!" she shouted, "It was a trick"

"No duh"

They staggered after Luke, but it was too late. Everybody converged on the creek as Luke ran across into friendly territory. Danny's side exploded into cheers. The red banner shimmered and turned to silver. The boar and spear were replaced with a huge caduceus, the symbol of cabin eleven. Everybody on the blue team picked up Luke and started carrying him around on their shoulders. Chiron cantered out from the woods and blew the conch horn. Looks like they won.

"Not bad, hero," Annabeth's voice was heard.

Percy looked, but she wasn't there.

"Where the heck did you learn to fight like that?" she asked. The air shimmered, and she materialized, holding a Yankees baseball cap as if she'd just taken it off her head.

"You set me up," Percy said angrily,  "You put me here because you knew Clarisse would come after me, while you sent Luke around the flank. You had it all figured out"

Danny shrugged, "Yep, that was a plan"

"A plan to get me pulverized"

"I came as fast as I could. I was about to jump in, but ..." She shrugged, "You didn't need help."

Then she noticed Percy's wounded arm, "How did you do that?"

"Sword cut," he said. "What do you think?"

"No. It was a sword cut. Look at it"

The blood was gone. Where the huge cut had been, there was a long white scratch, and even that was fading. As they watched, it turned into a small scar, and disappeared.

"I-I don't get it," Percy said.

Annabeth was thinking hard, "Step out of the water, Percy"

"What..."

"Just do it."

Percy did as was told and almost fell over, but Danny steadied him.

"Oh, Styx," Annabeth cursed. "This is not good. I didn't want ... I assumed it would be Zeus..."

Before Percy could ask what she meant, they heard that canine growl again, but much closer than before. A howl ripped through the forest.

"Stand ready! My bow!" Chiron shouted on Ancient Greek.

Annabeth drew her sword.

There on the rocks just above them was a black hound the size of a rhino, with lava-red eyes and fangs like daggers.

It was looking straight at Percy.

Nobody moved except Annabeth, who yelled, "Percy, run!"

Danny tried to step in front of him, but the hound was too fast. It leaped over him - an enormous shadow with teeth - and just as it hit Percy, as he stumbled backward and felt its razor-sharp claws ripping through his armor, a cracking sound filled the air, like that of the electricity. The monster fell dead at Percy's feet. He looked up and saw Phantom standing near, his hand outstretched. People stared at him in shock. But he didn't care and stepped closer. He took out the bottle and poured water on Percy's wounds. They started to heal, to everyone's even further bewilderment.

-Olympus-

"YOU BROKE THE OATH!" Zeus and Poseidon shouted at each other at the same moment.

"This is your second time, and you are accusing me?!" Poseidon said.

"HE IS NOT MINE!"

"Sure, because throwing lighting could come from every god," he responded sarcastically.

"I swear on River Styx, I don't know who he is and where he came from!" Zeus shouted over the noise of laughing gods.

"Like we haven't heard that before," said Ares, shaking his head, "were you going to hide him from us until he will be sixteen? Or maybe turn that one into tree as well?"

"I'm actually curious as well. How did you hide him so well?" Hermes asked, "None of us had any idea about his existence until now"

"Well, if he isn't yours, who is this little bastard's parent?" Hera asked. She hated when her husband cheated on her.

"I don't know," Zeus said in defeat.

"Then do the same as Poseidon"

-Camp-

"Look, I-I don't know why," Percy said, trying to apologize, "I'm sorry...."

But they weren't watching his wounds heal. They were staring at something above his head.

"Percy," Annabeth said, pointing. "Um ..."

By the time Percy looked up, the sign was already fading, but he could still make out the hologram of green light, spinning and gleaming. A three-tipped spear: a trident. Looking at Danny, who choked his laugh, luckily no one noticed that, Percy saw golden eagle holding lighting above him.

"It is determined," Chiron announced.

All around them, campers started kneeling, even the Ares cabin, though they didn't look happy about it.

"My father?" Percy asked, completely bewildered.

"Poseidon," said Chiron, "Earthshaker, Stormbringer, Father of Horses. Hail, Perseus Jackson, Son of the Sea God"

"Zeus. Bringer of Justice, King of Olympus. Hail, Daniel Phantom, Son of the Sky God"

Well, now Danny understood the need of cover story.

A.N. Oh, Danny, you can't not to cause trouble.
