Well, due to the wonderful reviews that Sometimes Nightmares DO Come True (Nightmares for short) got I decided to indeed make a sequel. Thanks to all you guys!!

Oh, I almost forgot. This and Nightmares are set in an alternate universe. In Don's dream ( previously read in Nightmares) Leo's return was based off the 2007 movie, from when he went to the jungle. Although Good Genes technically happens before that, in this universe Good Genes came after instead. Hope that clears up any possible confusion!

P.S. If you don't like Donnie torture then your in the wrong story. =)

Chapter 1

Donatello never had much trouble controlling his anger before today. Not when Mikey blew up the whole kitchen because he left fireworks in the oven. (He'd never even found out why Mikey put them there in the first place.) Not when he spent countless nights repairing seemingly endless piles of heaters, shell cells, etc. only to receive no thanks whatsoever. And not even when Raph and Mikey decided to play "pin the sai on Mikey" in his lab full of dangerous chemicals. Luckily that had ended on a less disastrous note.

But now, for instance, was a completely different matter. An infuriating and maddening situation that threatened his very sanity. Donatello had seen many strange things in his 17-year old life. But never, never had he seen a 30' plasma screen TV thrown with enough force to actually stay lodged in a wall. A brick wall, at that. Seeing such a thing happen right in front of him was shocking, to say the very least, and in that moment one thing was certain in his stunned mind. Raph took steroids.

If Raph thought he could get away with making the expensive TV look like it was stomped on by Godzilla, then he seriously needed to think again. Pushing his rage down as best he could, Donatello walked over to said turtle and coolly asked him what enticed him to relocate the TV in such a place.

Raph puffed up in what looked like a mix between anger and guilt. Anger apparently won out over guilt. "If your such a genius, then why don't you put two and two together?" He growled and poked Donatello aggressively in the plastron with the last word. The force put into the action proved the poke to be more of a shove and as the purple clad turtle stumbled backwards from the move, he tripped and fell to the floor. His head hit the hard concrete floor and he saw black spots starting to cloud his vision.

He groaned from the pain that was spreading from the back of his head and tried not to black out. Suddenly Raph's worried face appeared above him, and he grabbed Donatello's arm to help him up. It took a few seconds for the most paralyzing of his dizziness to fade, and when it did he pushed Raph away. "Don't touch me!" He hissed, his anger from the ruined TV quickly being replaced by a new, more powerful fury. Two days ago, he had dreamed about ripping Raph's neck apart and now he wanted to do it for real. Wincing when he felt the back of his head, he brought his fingers back into view. They were covered in blood.

"Donnie! I'm sorry, Don! I-I didn't mean to!" Raph pleaded with Donatello as he stumbled toward the infirmary.

The apologies were ignored and as he reached his destination, a wave of pain gripped him. He doubled over and cried out as his body started to tremble violently. What was making him shake? He got his answer as the voice he hadn't heard from in two days laughed maliciously inside his head.

You actually thought I would leave so easily? No Donatello, I'm not leaving until everyone in your family has been ripped into a million unrecognizable pieces. The monster's voice cackled in delight and Donatello's tremors got worse. His eyes snapped closed and he fell to his knees.

He coughed in between gasps for breath. "Wh-why? Why do you want to k-kill them?"

Beside his brother's shaking body, Raph recoiled in surprise at the words he heard. "Don? What are you talking about?"

Donatello ignored him as the voice spoke once again, but this time it spoke in a soft tone. I know what you wanted to do to Raphael back there, Donatello. You wanted to hurt him, like he's hurt you. You want to hurt them all. But I know you, and I know you could never hurt your family. That's why I'll do it for you. I shall free you from their disgusting grasp. It spoke as if it was trying to help him. Like it was his best friend, like it knew what was best for him.

Tears started to spill from Donatello's tightly shut eyes. He felt his consciousness start to slip away from him. He reached for it, trying to hold on, but it slid through his fingers like air. "I won't let you." Donatello yelled at the voice with all the energy he had left.

With nothing left to go on, his shaking stopped and Donatello went limp. Raph caught him before his head hit the floor.

The time for your salvation has almost arrived.

Donatello succumbed to the darkness, letting it take him into the realm of the unconscious.

Wow. This went in a totally different direction than I planned…

At least Psycho Don revealed his reasons for wanting to take over Sane-Don's body.

The way Psycho Don (Let's call him PD) talks about the things he does, it creeps me out! Gahh it makes me glad I don't have one of those voices in my head….

And I do think that Raph takes steroids. Where might he have gotten them? Maybe Casey??

Anyway, thanks for reading! And if you choose to review, PD will give you a virtual cookie!!

See? PD can be nice!!
