Confused by Time (Percy Jackson fanfic) (currently being rewritten)

Chapter 17 - Train or Death

Percy stayed in the cabin for less than an hour before he had to do something instead of just lying on his bed and throwing a dagger at the ceiling. He buckled Riptide and Oceanus' sword at his waist, grabbed a camp half-blood shirt (without sleeves, despite his scars), and changed his pair of jeans for shorts before striding from the cabin and heading to the arena.

In the arena the Hermes cabin and Ares cabin were practicing, and they all fell silent as Percy walked over to the dummies, ignoring the campers as he did so, and unsheathed Oceanus' sword. He took a breath and settled into his ready stance, his vision focused intently on the straw figure. His mind imagined golden eyes emblazoned into the straw, and an aloof expression. Percy glared daggers at the dummy and lunged forward, feeling immense satisfaction as the sword broke straight through the armour and buried itself up to the hilt. Percy forced his sword up, splitting the dummy in two, and pulled it out before decapitating it. The golden eyes staring at him faded away, and Percy's hand tightened on the sword hilt.

He looked behind him to check if anyone was still staring and glared at a few offenders before turning back to the dummy and concentrating. He fisted his left hand and there was a faint golden glow around the dummy which went back in time until it was fixed. Percy lifted Oceanus' sword and attacked the dummy again, feeling his mind focus on the dummy which now had deep sea blue eyes in Percy's head. Percy imagined he was cutting off Oceanus' arm as he attacked the dummy, and then he lopped off his head.

"What's the dummy ever done to you?" A voice behind him asked, and Percy instinctively twisted to bring the blade down on the speaker's head, but she quickly raised her spear to block the attack. The wooden shaft was cut straight through, and the demigoddess hurriedly jumped to the side.

Percy's eyes widened as he looked down at the remains of the spear. "Oops, sorry," he mumbled.

"Since when did you get so strong, Prissy?"

Percy shrugged. "Titan strength."

Clarisse nodded and bent down to pick up the two halves of her spear, but Percy beat her to it. He held the spear parts together and his eyebrows furrowed in concentration before the halves moulded together seamlessly. "Cool trick," Clarisse said grudgingly.

Percy frowned. "Not really. It's Lord Kronos' abilities. They're not mine." He handed the spear back to her. "Did you want something?"

Clarisse looked at the destroyed dummy. "You seemed annoyed by something, and I didn't go down into Hell to get you back for nothing."

Percy scowled. "I'm annoyed that there's this constant reminder of what's happened recently."

"You didn't have to wear short sleeves," Clarisse said pointedly.

Percy bared his teeth. "Not that," he hissed, turning back to the dummy and waving his hand to change it back. "It's my damned speed, the strength. Everything has changed! I feel like part of me has just faded away!"

Clarisse frowned as she watched him savagely rip the non-existent intestines out of the dummy. "Alright. That's enough." She grabbed his shoulder, ignoring the threat that was spat from his mouth, and all but dragged him into an empty area of the arena. "Sword out. Come on."

Percy turned and studied her. "I don't think you want me to do that."

Clarisse raised an eyebrow and backed up a few paces to ready her spear, thinking that she was very grateful for putting armour on today. "Try me."

Percy's mouthed twitched slightly and he shrugged. "It's your funeral I'm worried about."

Clarisse grinned. "Are you scared, Prissy?"
