"How did this even happen?! Guys? Are you here?" April shouted in question after coming in to check on the turtles but their lair was a mess with a sloppy coat of blue paint all over. The nearest turtle in the middle of the blue chaos was just standing there with mixed emotions on his face.

"What happened...? Can you guess since there's TWO of me?" From behind him, another Don with a hug mug of coffee grumbling nonsense.

"A,B,C, Monkey in a tree, 2,4,7, can't get to heaven, ladies and gentleman...ZEEEBRAAA!" He yelled, waving his hands, spilling coffee all over the real Donatello who hissed in pain, then he collapsed on the couch and began to loudly snore.

The burnt Donatello who was still standing was miraculously keeping his fury in check while Leo came in looking exhausted. Noticing his older brother enter Donatello glared at him and snapped, "LEO! Why did you make him copy me?! My LABORATORY is a mess because of you!"

The leader sighed, "Sorry Don, it was either your lab or my Katanas, anyways you can always just upgrade your lab again."

"That's not the point! Mikey completely and utterly disorganized my lab and downloaded online documents from other planetary systems without the proper codes to protect my data! Everything I had on Mikey's illness...is all gone now!" Donatello groaned despairingly.

"Wait, calm down guys and greetings April!" Don/Mikey sang as he suddenly perked up and picked up a fallen clipboard.

"I went ahead and took a look at your research and I believe I have a theory on your unidentifiable problem whose answer has continued to evade you. I hope you can forgive me for being a tyrant but I think you'll like what I have found." Mikey/Don continued as he ushered the others into the messy lab.

"Ok...so what did you find Mik-I mean Donnie?" Leo asked curiously, knowing when Mikey was another 'Leo' it was like he was a copy with almost the same abilities. If this was the same, than maybe he is almost as smart as Donatello. Almost, this was still Mikey...right?

"I thought you would never ask! My results conclude that the issue with this 'Michelangelo' is that his brain, in simpler terms, is being rewritten from a foreign source for example; a computer virus implanted in a memory chip."

"How can that be possible Brainiac? Mike's not a computer, he's a turtle and why isn't he in bed resting?!" Raph said from behind April who screamed in fright at the unexpected entrance of the steamed turtle.

"Not now Raph, I am in the middle of a theory!" Mikey/Don shushed him as he flipped though some encrypted notes he had printed out.

"What the shell?! Mike?! What are ya doin with Don's mask and-" Raphael started to say when he was cut off by everyone's "SSSSHHHHHHH!"

Mikey/Don unaware of the situation kept talking without missing a beat, "The symptoms were merely a distraction to keep us in the dark of what was really being done here. My educated guess on how it was even inserted into the poor guy without detection was injecting it into the shell. You didn't check that part thoroughly enough Donatello but I can see why...it smells of decay. Which means whoever did this...did not expect the results we are seeing."

"What do ya mean?" Raph asked warily.

"They did not add in the mutagen factor which would have made this more stable and devastatingly much more effective." Mikey/Don answered.

"You implied that there was an objective to all of this, why go through all this trouble to rewrite your memories? Or anything really? If they want information they could have asked." Donatello asked, reading the notes and formulas that held proof of his little brother's intelligence.

"You're really getting into this aren't you?" Raphael said, nudging Donatello who was in deep thought.

"Is this all true Don..?" Leo whispered to the real Donatello, who nodded in confirmation.

"Everything he said is logical, according to his findings at least." Donatello replied.

"Ok, let's say this is all hard fact...what is their true goal in doing this? It doesn't make any sense! Just a big waste of time...unless-" Leonardo trailed off as Mikey/Don agreed.

"It would be a big waste of time...if it was Michelangelo who was the target. I believe whoever is responsible for this madness wants to destroy the heart in order to get to the rest of the body."

"So a master plan to kill us...like that hasn't been done before." Raph said sarcastically.

"But this way it's more effective." said a yawning Mikey/Don.

"But who would do this...? And when did they get a hold of Mikey long enough for this..." Donatello muttered, typing into the computer with Mikey/Don working beside him.

"We have too many enemies to choose from but let's shorten it down to the past half year." Don/Mikey said as he put more coffee into his mug, than into his brother's.

"Thanks." Donatello said politely, giving little thought to the others who appeared to be in shock.

Shock, because Don and fun loving-deadly sick Mikey was keeping up with Don's work ethic, plus working together.

"Holy shell...it's like watching two Brainiacs!" Raph muttered, while Leo patted their heads and escorted April home, who was only there to drop off comics with food. It was only supposed to be a quick visit, not a five hour discussion. After awhile of watching the duo work, the hot headed turtle went to bed.

Raphael's P.O.V.

'This is crazy...all of it. I'm not sure if that's even my little brother anymore, but one thing's for sure...this place is a mess with a bad paint job.'
