Greg had driven them home since Sonic still was a bit weak knee from the sleep gas, they had finally removed the tracking chip then destroyed it. Which Tails was very relived about, but it left him worried why Sonic felt so strongly that he had to go up and confront Eggman.

"No I can handle it myself" Sonic pushed of his friend. "Just let me go deal with Egghead"

Tails shook his head "Not yet, you need to rest"

"I'm just going to be up again when I change, what does it matter?"

"Just go lie down." "Fine..." Sonic plops down on window seat in the upper level of the garage, muttering along the way.

The fox looks over the data he gathered over time from the transformation. And rubbed his head, he still couldn't explain how there was all negative energy inside his friend.

He was sure it wasn't forced in at all...But then how did it get there?

Tails sighs "I'll be right back Sonic, please don't leave. I'm just getting something for us to eat"

Sonic nods though his face still seemed a bit irritated.

Tails makes his way into the kitchen. Quickly he goes though the cupboards, just grabbing random snacks and putting them on the counter. All the while thinking about his friend.

"I just wonder why Sonic's bothered. I know what Eggman did but normally he doesn't let it get to him like this"

Picking up a box of crackers the fox sighs. "Could it be possible somehow he's getting worse? All those negative emotions- the frustration Sonic must of gone though. No doubt he was also worried what would happen if the doctor found out who the beast-"

There was a knock at the door, so he goes to see who it is.

"Oh Rouge, Shadow what brings you two here?"

The white bat smiles "Just checking up on you kids, and seeing if you have any news."

"Well she wanted to check up, I was just dragged along" Shadow said. Which Rouge gave him a glare for.

"Then come in, it's just me here right now most of the gang is downtown" Tails stood back to let the two agents step inside and follow him to the kitchen. "Sorry about the mess"

"It's nothing" Both took a seat and watch Tails puts stuff away and in piles.

"So how's the president?"

"He's good, just a bump on the head and also some cuts and bruises"

"Glad to hear that and that you guys were there"

"Thank you"

"..."

All three sat there for a minute or two with out saying a word. When a sudden scream of pain got everyone's attention.

Tails knew right away who it was: Sonic. "I'm coming!"

"Wait, what's going?" Rouge asked but got no answer when Tails raced out of the house and towards the garage. So both her and Shadow followed the fox.

All three of them them stop in shock when they see something so shocking and bizarre.

Sonic was withering on the ground, fangs were growing in his mouth, Tails looks at his friend in utter disbelief. "B-but this shouldn't be happening. N-not yet" Shadow noticed that and his eyes widen when he put together what it meant. He could see Sonic's fur darken and muscles starting to bulged.

He was the monster that attacked before. That's why Tails wanted to help it before.

"What's….URG! ACK! T-Tails what's going on?" Sonic's whole body shook as the fox looked at him in disbelief

Sonic's ears and tail lengthens, becoming more predatory

His arms extends and the talons reappear at the end of his fingers

"I don't know Sonic" Tails shook his head sadly. "Just hold on" "T-trying to"

"What exactly is going on here?" Rouge asked reminding Tails of their presence. He jumps a little, having forgotten them being there. Looking at them he says. "Nothing"

"This is a pretty big nothing" Shadow stated crossing his arms. "There no way you are going to be able to convince us this is nothing to worry about. I think you owe us some answers"

"..." Tails looks back to Sonic. "Not yet."

"Tails I suggest-" Rouge was stopped by him. "I didn't say not but now is not the right time, just wait.

So they waited...till Sonic's change was done. Then was Tails ready to tell them.

How he discovered abnormal levels of dark energy inside Sonic.

His transformation at night due to it.

Being captured by Eggman, then chipped and having the control collar placeed on him.

Then Sonic's escape and them going to have the chip removed. So he couldn't be tracked.

"So the doctor does not know of Sonic's condition?" Shadow questioned putting his hand together and leaning his head on them while keeping his eyes on the two tailed fox.

Tails shook his head. "No, we're lucky on that part."

"And he can't talk like that either?" Rouge glanced the Beast Sonic. He looks back at her then shrugs.

"Yes, I haven't been able to explain that well. I just figure it's part of the transformation." Tails sighs. "Can you please keep this between us? I'm worried about what would happen if anyone else learn of this."

"Very well Tails. But you must let us in more." Shadow said while Rogue added. "You never know we might be helpful."

"Deal."

"What can we do first?"

"Well it would help if you guys keep a eye out for trouble at night. Sonic has to stay here and I have to keep working. So neither of us can show Eggman if does."

"Understood."
