Percy's Payback

"GUYS IM OVER HERE!" Nico cried out to the group, who had come running around the corner and run straight into where he was behind held, surrounded by a cage of earth which he was unable to break no matter how hard he tried. The group stopped and stared at him in confusion, like they didn't recognise him, even Hazel.

"Do we know you?" Piper asked, raising an eyebrow.

"YES! Well actually I don't know you, but the others...GUYS LEMME OUT, ITS NICO!" They looked blankly at him.

"I'm sorry..."Annabeth muttered walking forwards. "But I've never seen you before in my life!" Nico was about to protest when he saw Percy, smirking like an idiot.

"Ha ha very funny, I get it I get it, now please let me out!" Percy frowned.

"What's funny? I think this is quite serious, for all we know your some terrible titan just coaxing us into letting you go."  Sighing in frustration Nico looked towards Hazel, his last hope, the only one who could stop the madness.

"Hazel, come on, we don't have long, just let me out!" She shook her head. "IM YOUR BROTHER! This is stupid you're going to get us all killed."

"I suppose we could just let him out..." Jason offered. "Take away his sword, make sure he can't hurt us."

"You're not taking my sword!"

"Stay here and rot then." Percy told him simply, turning his back and crossing him arms, under his breath counting down 3...2...1...

"Ok ok!" Nico flung his sword between the bars of the cage and Percy picked it up.
"Exploding arrow?" Frank asked, holding a hand out to Leo.
Leo started jumping on the tips of his toes as he  pulled 3 silver arrows from his rucksack.

"Duck." Hazel warned Nico as the first of the 3 arrows hit its target. The explosion was so large it  knocked all 7 of the other demigods off their feet and managed to sear the hair on Nico's arms away.  When he eventually looked up there was a huge hole in the side of his cage, which he immediately crawled out of. Around him the others where peeling themselves off walls, coughing from smoke.

"Jeez Leo, did it have to be quite so powerful?" Jason asked.

"Gaea is strong here, it had to be that big to burst through." He replied, picking up some fallen things from his belt, a screwdriver, a mini hammer...

"You know..." Percy frowned, rubbing the back of his head. "The fall seems to have rid me of my amnesia. I think I remember you now Nico." Nico frowned.

"That wasn't funny."

"No." Percy told him. "It wasn't, so what lesson did we learn Di Angelo?"

"We need to give Leo less gunpowder?" Piper offered.

"Is your name Di Angelo?" Percy asked smirking, playing the role of a real teacher.

"Give me back my sword Percy."

"What's the lesson?"

"My sword."

"Lesson." Nico sighed.

"Not to pretend you don't know someone when you really do." Percy smiled proudly, then pulled Nico's blade out and handed it back over.

"I'm glad you're safe." He added earnestly, "You're a lying little pain in the butt, but I kinda missed you."

"Whatever." Nico huffed, joining the others in the group and leaving through a tunnel Leo had made with a small bit of dynamite he had handy.
