Hi! I'm back...okay so it was only about a week since my last update. But now I've got a new update! But first, I'd like to comment to some reviewers:

Destinies: Thank you for the review! I've got an update for you right here. I'm glad you like the fic!

Samantha 27: Actually, Amy doesn't know who her killer is. Amy hopes Sonic can figure out who based on what she was able to find out.

N7 and Kat: I love getting so many reviews from you guys! It's wonderful!

To all my other reviewers: Thank you! You make me feel so happy inside!

And now on with the fic!

Sonic stared at the small metal disc Amy had included with her letter. On the side was etched a location, the place where he stood now. He looked up at the building. It wasn't a place he recognized. It was meant to be some sort of clue to who the killer was, but Sonic couldn't see what the clue was supposed to mean.

Sonic walked through the front door. The floor beneath him creaked uneasily, but Sonic paid it no mind. It seemed he was in some sort of old factory. Deactivated machinery hung from the ceiling and a conveyer belt rested forever beneath a thick layer of dust.

That's when the walls caught his eyes.

Along the walls were streaks of red. It was easy to tell they were not from paint by the erratic haphazard way they were. In places it splattered; in other places it had obviously run. It was blood.

The heart within Sonic that normally would have gotten concerned felt nothing. His eyes raked along the walls without as much as a wince. He didn't care.

Sonic threw the metal disc he held in his hand to the floor. A factory…why did you lead me to a freaking factory? Sonic wondered hopelessly.

An ancient computer rested in the corner, and Sonic booted it up. Pictures of schematics appeared on the screen suddenly. Sonic stared, barely understanding any of the technical stuff. Instead he examined the pictures. It seemed that robots had been built here before, but they looked nothing like those Eggman would build. Maybe the murderer made all these, Sonic guessed.

Sonic looked around the building, a deep hatred growing within him. The murderer…if this was his building…had made even more killing machines. Sonic gritted his teeth. No, the killer was not going to make any more.

A ring ejected from the device on Sonic's arm, and Sonic wrapped his fingers around it. He felt the power coursing through him. He pulled himself into a ball and threw himself at the walls. He broke them down within seconds. Within minutes, the building was a pile of rubble.

Sonic stared at the remnants as the power of the ring faded. He felt no remorse for his actions. He narrowed his eyes instead. This is just the beginning, he thought.

And he ran.

Rouge felt her eyes go wide when her supervisor told her of the building Sonic had destroyed. "No way," she said with a smile. "He would never do that."

Shadow seemed to think differently. He glanced sideways at Rouge. "The hedgehog's cracked. Isn't that obvious?"

Rouge shrugged. "Whatever you say, Shad. But this sure doesn't seem like the Sonic I know."

Her supervisor nodded. "I'd agree with you, Agent Rouge, but we have video proof. Sonic the Hedgehog did cause the vandalism"

"Shads is probably right; Sonic's cracked. He just lost Amy after all. But what do you want us to do about it?"

"The commander wants you to follow him, intercept him if possible. Don't irk the target, but find out what's going on inside his head."

Rouge smiled. "It's not going to be that simple. But I can think of a way to make things easier."

By the look on Shadow's face, Rouge knew that Shadow already knew what she was thinking. "Rouge…" he growled.

The moment Knuckles's ears caught the sound of flapping wings, he sprung up and stood directly in front of the Master Emerald. He held up his fists. No way was Rouge getting through him today.

However, when the bat landed, there was a look on her face that scared Knuckles. "What's wrong?" he asked, being careful not to move from his defensive position in case this was just a ploy.

She gave him the slightest smile. "I need your help."

Knuckles looked at her, shocked. "With what?"

"How good are you at catching hedgehogs?"
