"He couldn't have been lost a long time ago," Mikey said, laying back on the tire swing. "He was with me for a while before we split up at the alley."

"This is most distressing," Master Splinter sighed, stroking his chin.

"First Casey, now Leo," Raph said from his usual spot at the beanbag chair, his eyes to the ground and his brow furrowed.

"This is too much to be a coincidence," agreed Donnie. "We're under attack."

"This is where I last saw him," Mikey said, gesturing to the split in the path. "He went that way."

"Come on," Raph said before starting down the right path.

The four of them scrounged around, looking for any clue of Leo's disappearance

April put her hand on her head, suddenly getting the feeling that she should be looking in the left alley. She looked in that direction before starting down, and Mikey, who was the closest to the left path, looked up from the ground where he was searching.

"I'm sure he was here," he said, seeing where April was headed.

"It couldn't hurt to check."

Mikey looked at her, at the alley, and back at her before nodding.

She started down the left path, following her senses for a while until they led her into another, extremely short, alleyway. She was between three buildings now, one in front of her, and two at either side. She looked at the building to her right. There was a dumpster pressed against its brick wall.

It took April a moment to see the figure in its shadow, slumped limply against the brick, its arms drooping in odd angles, its head rolled down to rest on its shoulders.

"Leo?" she gasped.

She turned away from him with the realization that she was being watched. She held her tessen in front of her, ready to attack.

There was a sound, very subtle, but it let her know where her pursuer was. With a flick of her wrist, her tessen was flying through the air. It soared right into the shadows of one of the fire escapes on the centre building. The tessen did not return.

Did he catch it?

She watched and waited, assuming a defensive position.

Where are you?

There was the sound of footsteps behind her, but before she could turn to look, she was out cold on the ground.

Donnie looked up to see Raph gazing around, an unusual look of worry in his eyes. Don knew that was concerned for Leo and Casey and, wished he could say something comforting to him, but he knew that his immediate older brother would brush him off, not wanting to let them know that he was afraid.

Donnie looked for Mikey to see if he had noticed, too. Raph was always more open to Mikey than anyone else. Maybe he could do something about it.

"Mikey?"

Donatello looked down the alley. He was not there, only Raph. He looked to the other side, and sure enough, there he was.

"Wait, where's-" he looked from side to side again. "April? April!"

"I don't understand, she was there one minute, and then she was just... gone!" Donnie said, pacing outside his lab.

Master Splinter stroked his chin thoughtfully, his eyes closed.

Michelangelo sat on the couch, looking quite pale. He stood and started to walk to his room, but Raph stopped him, grabbing him by the arm.

"Mikey, did you see where April-" but he stopped when his eyes fell on Mikey's wrist. When he had grabbed him, his cuff had slipped back, exposing a deep red gash in his skin.

Michelangelo jerked himself free of Raph's grasp.

"Mikey!" Raphael gasped. "What happened? Did he attack you? Who is he?"

Donnie walked behind Mikey and put his hand on his little brother's neck. Mikey's eyes rolled back into his head, his knees gave out, and he started to fall, but Donnie put his arm out to support him. The youngest's eyes were closed, and he hung limply over his brother's arm.

"DONNIE, WHAT-" Raph started, but he stopped when he saw what Donatello was looking at.

He held in front of him a kraang mind control device.
