Thanks to all my amazing reviewers who have helped me with this story! Here's Chapter... (pause for effect) 7!

-:-

Leonardo saw a silhouette on a rooftop far away. Heh. For a second there I thought that was... wait... Karia?


When Leo got back to the lair everyone else was asleep. Ugh. I'm not going to wake them up, I'll do this by myself. The blue clad ninja crept silently into Donatello's lab hoping that he had perfected the mutagen. On the side of one of the tables in their sat a syringe of a orange liquid. That's it! That's retro-mutagen! Leo grabbed the syringe and ran out of the lair. He quickly climbed a high rooftop to spot Karai but he didn't see her anywhere. NO! She has to be here! Leo ran across the rooftops to the spot where he saw her before but she wasn't there! Then a tail whipped out from behind him and knocked him off his feet.

"Ow!" Leo landed with a thud on the backside of his shell.

"Hisssss." Karia came out from behind an entryway to the apartments below.

"Karai! I'm here to turn you back to normal!" Leo said and held up the syringe for her to see.

The snake's eyes widened in fear. She remembered Shredder had captured her back and one of his mutants had tried to experiment on her. Luckily she had gotten away before they could do any harm. Now she didn't trust anyone with needles, not even Leo. She lashed out and bit him on his hand which made him drop the syringe.

"Karai please! I don't want to hurt you!" Leonardo said and picked the needle back up.

But she wouldn't listen and continued to attack the turtle. Karai whipped her tail to make him trip but he jumped over it. Leo had no choice but to defend the assault from the snake. He pulled out a katana with his free hand just in time to dodge a blow from one of her many snake heads. He blocked another blow from her tail and one more from her gaping jaws. He then realized that this was a losing fight if he was only going to defend. He dropped his katana to the ground then pulled out the other one and dropped it.

"Karai please stop! I'm your friend remember? Leonardo? Please, I won't hurt you." He said trying to coax her to calm down.

The white snake stopped for a minute. She cocked her head to the side, and then lunged again biting Leo on the shoulder. Her tail whipped his hand and the syringe soared upward into the air.

"No!" Leo cried but it was too late.

The vile crashed on top of Karai's head and she hissed in pain as the retro-mutagen started turning her back to normal. She whipped her head around violently which resulted in the retro-mutagen splattering all over Leo.


Donnie couldn't sleep. He'd had a nightmare and didn't feel like going back to bed. He came out and went into the living room to sit down and think. Sometimes he'd even fall asleep on the couch.

"What is troubling you, my son?" Master Splinter entered the room and sat down by his son.

"Just a nightmare sensei." Donatello replied looking down at his hands.

"And?" The old rat questioned.

"And it was about Leo. He went off on his own to go and save Karai but she attacked him." The purple clad ninja said still looking at his fingers.

"Where is your brother, Donatello?" Master Splinter inquired.

"In his room asleep I think... Wait!" Donnie ran out of the living room and into Leo's room to find that he wasn't there. "Leo! This isn't funny!" Donnie whipped around expecting to find him laughing in the doorway. But he wasn't.

"Master Splinter!" Donatello ran into the living room out of breath. "Leo's not there."
