Lost Memories: One strange device (Prologue)

The young fox was in his lab, concentrating.

SUDDENLY, a blur burst in, the fox was shocked because of the sudden noise and wind.
"Ahhh!" he screams.
"SONIC! What are you doing?!" he asks the blue figure.
"What, can't I visit my best buddy or something?" he answers.
"Grrr", the fox growled in annoyance.
"Sonic, don't you see that I'm working on a really important project?!

Sonic closes by, and looks at the machine, wondering what it can be.
The object was small, it could fit in his hand. Something about it made it look like a lazer. Sonic just stared at it, and that made the fox nervous. He didn't know what reaction to expect.

"Uhm, Sonic. What do you think?" he asked...... No reaction. "Sonic?" the fox asks with a small voice. Still, nothing. There was that awkward silence for almost fifteen minutes.

Sonic felt light headed all of the sudden. He grabbed his head with his right hand, and stepped back. He sat down on the couch, in the center of the lab. He groaned.

"Is everything alright Sonic?" the fox asks again. Sonic still couldn't hear anything. His mind kept thinking about that device. He tried to stand up again after a few minutes, when he felt better. That was a mistake, he cried and fell unconsious.

"SONIC!! Wake up Sonic!" the fox boy screamed. The hedgehog opened his eyes and stared at him, with the same cold stare as before with the machine. He blinked and said something. Nothing a human or mobian could hear. He closed his eyes again. A few minutes went by and he finally woke up.

"Tails" Sonic said with a weak voice.
"Finally, you're awake." Tails said with a smile. "What was up with you right there?" he asked. This time, Sonic could hear him talking, he just didn't respond. Tails was full of questions. Sonic stood up shook his head and walked to the table with the device again. He stared yet again. This time the only thing that happend was that a lot of memories were heading back, the first time he ran past the speed of sound. The first time he met Eggman, when he met Tails, Amy and Knuckles. He had something in his mind and blasted of.

Tails was stunned, he had never seen him like that before. What was wrong with him, why did he leave like that? And most importantly why did he faint of his device?
