1(A/N: This is what everyone was asking for... And now I added a couple of twists and made it into a whole story. I was contemplating on actually starting this multiple chaptered story now, with having two other stories to work on. But I decided that my cross over story and The Reason are two very important stories. But also, I thought this one was important too... SO, I added it to my collection. And now I am going to shut up. FINALLY HOME FROM SEATTLE!)

Don POV (This whole story will be that, unless I otherwise notify everyone.)

FLASHBACK

"Leo... You can control the others... Right?" I asked my brother.

"Sometimes... Yes." My elder brother replied.

"Then tell them... Tell them I quit. I quit being the brain of the family." I stated.

"But... B-But Donny... You can't do that."

"Yes I can. They always tell me what to fix... It's always 'Donny, fix this!' or 'Don fix that!'... I'm tired of it! I always fix what they ask me to! And I never get a thank you from them!" I snapped. Leo was the only one there for me. He always supported me and helped me. I don't know what I would do with out him.

"No... Donny... Our family wouldn't function without your brains to help us. We need your brains. Please... Keep doing what you're doing... Not for them... For me. Do it for me."

"Fine. Only if you promise me one thing." I answered. He gazed at me.

"What do you need?" Leo questioned.

"Never leave me... Please... You're the only one who is actually there for me." I begged. He smiled that contagious smile, that every time you see it, you have to smile back.

"I promise."

"Pinky swear?" I asked, to make sure he was telling the truth. He chuckled softly, and it vibrated in my ears. I held out my pinky finger. He looked down to it, then held out his own and linked it around mine.

"Pinky swear."

PRESENT

I sat at the desk I was being forced to work in. I squirmed in discomfort.

I hate being the one to fix the shell cells. This one was completely smashed. I finally groaned and threw my screw driver across the room when I finished.

I thought I was only going to do this if I got a 'Please' and 'Thank You'.

But I didn't get that.

Nope. Nada.

I look up to see Leo standing there. I jump.

"Leo! You scared me!"

"Oh... I'm sorry Donny. What are you working on?" Leo asked.

"Raph's shell cell. Got it smashed... Again." I answered. Him and I continued talking for a good half hour, when Raph barged in. I jumped again, turning towards him, cursing. "Raph... Don't do that when you can clearly see I'm talking to..." I turned and trailed off when Leo was no where in sight.

"Whatever." Raph rolled his eyes. "You done with my shell cell yet?"

"Uh... Yeah. I finished it about half an hour ago, then I talked to..." Raph cut me off.

"Who? Leo?" Raph asked, sounding annoyed and angry. Why? Leo's his brother too.

"Uh, yeah. Who else can I talk to that can actually understand what I am talking about?" I replied. Raph sighed.

"Don, stop doing that, okay? Leo can't talk to you! He's dead! He's been dead for a good month now, all because of you! Now stop playing around, and join us in reality!" He snapped and jerked the device he came for out of my hand, before storming out of the room. Tears filled my eyes, and I looked down at my pinky. The one Leo and I swore with.

No! He couldn't be dead... He can't be dead... It's impossible for beings like my brother Leonardo to pass away!

Then I remember.

The incident.

That only involved Leo, me, The Foot, and The Shredder. The one that stole my brother's life and let me keep mine.

He actually could have done something with his life. I only would have made out to be some lame scientist... He could have been a dozen more people's hero's than mine. He could help others brush up on self defense... If he was human, he could do anything!

Oh yeah, there's that fact.

If he was human.

I bet, if he was human, he would also be alive! Stupid mutagen! Stupid... Everything!

Wait, what about what Leo and I swore about? Him not ever leaving me?

I am still sitting there, gazing down at my pinky.

So much for that promise.
