Percy stopped at the doorway, listening to the sounds of battle inside. The door was closed but he could easily open it, but wanted to know what he was getting into first. From the sounds of it, only two people seemed to be fighting. But then there were the sounds of a bear, of a bird, of paws hitting the metal floor.

The shapeshifter.

"Jackson." Clarisse was suddenly behind him. "What's in there?"

"I think someone's fighting the shapeshifter." Percy clung to Riptide. "Are you coming in with me?"

Clarisse kicked the door open as her answer. "Don't get in my way."

Will looked over his patients, smiling at the work he had done. He had healed Amy, he had gotten Chris mostly healed. Jesse and Lethia were stable, Nico was stable. The only thing he was worried about was Nico's sight. It was time to check it, time to see if his boyfriend would be blind or not.

"You ready?" Will moved to Nico and began to wipe the liquid off of his closed eyes. "This is it."

Nico clung to Will's shirt, letting him clean him off. "I...I'm ready. It's going to be okay."

"Exactly. It's going to be okay." Will finished wiping the "medicine" off. "Okay. Open."

Nico hesitated briefly before opening his dark eyes. They had grown lighter, didn't look so black anymore. He stared at Will, however, stared into those blue eyes. "Why do you look so worried?"

"Nico!" Will couldn't stop himself from yelping in happiness. "You can see!"

Nico gave him a tired smile. "You act like you just found the holy grail."

Will pecked Nico's lips before jumping up. "You all see that? Nico di Angelo isn't blind! I worked my magic!"

Lethia clapped sarcastically. "Brilliant."

"Oh, shut up." he did a small victory dance before sitting in the chair by Nico's bed. "You feeling okay?"

Nico nodded. "How are the others? You really haven't heard anything?"

Will shook his head. "Not a word."

"Maybe I should go help..." Nico looked at his IV's. "They might need it."

"You're not strong enough." Will crossed his arms. "You're staying here. Doctor's orders."

Annabeth slammed against the wall with a grimace of pain, her dagger falling to the floor. In the time it took her to regain her breath, she saw that Percy and Clarisse had already engaged the shapeshifter. Three people...maybe they could do this...

"Plan 110!" Annabeth called out, picking her dagger back up. "Percy, Clarisse! 110! I'm one, Percy two, Clarisse three!"

Clarisse nodded her approval, circling the man with her teeth bared. "I love being person three."

Percy, however, had time to pout. "I don't want to be two-" He ducked at the last minute, the sword slicing above him where his neck had been. He moved to kick the man's stomach, but he was suddenly a bird and in the rafters again.

"He can take people's abilities!" Annabeth called out. "Don't let him touch you! That means he has the abilities of a son of Apollo and a son of Hephaestus. Watch out."

"This guy won't keep still," Clarisse growled. "How is Plan 110 going to work on him?"

"It will," Annabeth promised. "Just stick to it."

Percy closed his eyes before smiling. "Annabeth...I think you're right. Plan 110 will work."

Clarisse threw a knife at the bird, the blade slashing across its stomach. It fell to the floor, turning back into a human at the last second. "There, Jackson! The blade was poisoned!"

Percy closed his eyes and raised his hands. He could sense the water nearby, sense it running through the pipes of the building. In seconds, his ears popped and a roar of water was at his disposal.

The water fell onto the man who was busy trying to heal himself. Coughing, spluttering, he tried to transform into something that could breathe underwater. Nothing worked in the state he was in.

"Got him." Annabeth jogged to the man and put the tip of her dagger at his throat. "Tell me your name, who you are, and how you took those demigods' powers. Now."

He glared up at Annabeth, brown eyes full of loathing. "You insolent daughter of Athena. You have no idea how it feels, forever in the shadows, hiding your very existence. You have no idea how-"

She pressed the knife closer to him. "Tell me who you are."

He smirked. "I think you know my distant cousin. Frank Zhang? Does that ring a bell?"

Annabeth glared at him. "So that's how you shapeshift. It's in your genes."

He shrugged. "Guess so."

"Should we kill him?" Clarisse asked. "I will."

"There's no other way to stop him." Annabeth slit the man's neck. "Sorry, distant cousin of Frank Zhang."
