Older Leonardo walked along the pearl-white tiles of the hallway, his feet slapping the ground and causing a seemingly everlasting echo throughout the corridor. He breathed out and held on to the handle of a large door with a painting of a computer painted on it in purple.

The door creaked open and the dusty air surrounded Leo in a grey mist as he felt his way toward a large wooden work-table. He stroked several tools and half-finished projects which were gathering a large amount of dust before turning to where a wooden Bo staff had been placed. Tied around the staff was a long piece of purple fabric which had a pair of holes cut into it as if it was used as some kind of mask- Donatello's mask.

Leo pulled the fabric away from the staff and clutched it tightly into his palm as if he were afraid that it would fly away if he put it down. With a long and deep sigh, he sat himself down on the mattress and allowed the memories to come to him like a dream.

"Donnie! Pick up your pace you're falling behind!" a voice yelled. An older-Casey Jones ran through the alleys with an also older-Donatello following behind him. "What did Mikey say again? Head toward the south exit of the base?"

"No, Casey!" Donnie yelped, "Mikey told us the north exit! Weren't you paying attention?"

"I wasn't paying attention? Casey's voice was slurred as if he had been drinking. "You were staring at April pretty much the entire briefing of this mission! How do you know? Maybe you're wrong for once!"

"Casey, please!" Donnie's voice was almost pleading. "We need to head to the base and simply place this explosive on one of the walls so that Shredder's weapon ratio decreases. If we fail this, Shredder will make more innocent people suffer!"

"Bah! You're talking shi-" Casey was cut off from his curse as Leo dropped down in front of the pair, his feet slamming heavily on the ground causing Donnie to wince a little and Casey to stick his chin out. "Oh great! Now the all-powerful Leonardo's come to save the day once again!"

"Shut it, Jones," Leo snapped, he turned his head and glared at Donnie. "Why didn't you tell anybody that Casey was intoxicated with alcohol, Donatello? He'll blow this whole mission!"

"I didn't know he was drinking!" Donnie hissed, frustrated over the fact that Leo had assigned Casey Jones on a mission with him, of all people. "Raph and Casey work together the best with these missions, Leo! Why did you partner him with me? He never listens to anything I say!"

"Know-it-all," Casey simply grunted, reaching toward his pocket and pulling out a small bottle. Leo snatched the bottle just as Casey's lips touched the top and emptied it on the ground before smashing it against the wall.

"Well you have a new addition to your team, Donnie," Leo smirked, unsheathing one of his katana blades from the harness on the back of his shell. "We get in and then get out, preferably without being spotted, right?"

"Right," Donnie agreed, holding his staff while Casey saluted with a shaky hand. "Let's do this, guys!"

The trio ran stealthily through the empty streets of New York City, getting to Shredder's smaller base and cutting the wires of the fence without being spotted once. It had been raining earlier that day and the ground was still wet and the chilly night-time air caused a slight discomfort for the team.

"Secure, Donnie?" Leo hissed, watching as his younger brother set the explosives against the wall of the base on a timer. Donatello simply nodded and stepped forward to leave the area but a cruel laugh echoed around them.

Casey and Leo got into their fighting stances while Donnie looked around, trying to pinpoint the direction of where the sound of laughter was coming from. Claws scraped against metal which alerted Donnie to where the enemy was and he quickly jumped out of the way to avoid Rahzar who launched himself to the ground with his claws aimed at where Donnie's head would have been if he hadn't moved.

"Destroy the human and the blue-turtle!" Rahzar roared out his orders to his team of Foot clan members and the Purple Dragons. "But spare the purple-one!"

Those words were enough for Leo to hear as he ran straight at Rahzar with his katana blades. The destruction of their home and the killing of thousands of innocent people had changed Leonardo and he was determined to stop the Shredder, even if it meant destroying his henchmen to get to him.

"Leo!" Donnie yelled, gasping as Casey shoved past him roughly to fight off several Purple Dragons. "Casey!" he shouted, his voice sounding urgent. "The timer!"

Leo delivered a swift kick to Rahzar's skeletal stomach, sending him flying backward. Donnie stared in horror as Leo continued fighting close to the explosive...5, 4, 3... "Leo!" Donnie screamed, shoving Leo out of the way as the device exploded, sending Leo flying straight into Casey and causing them to crash into the metal-wired fence.

Leo groaned and sat up, realisation hitting him as his brother had pushed him out of range of the explosives. "DONNIE!" Leo screeched, abandoning Casey, who was unconscious on the ground, to dig under the pile of bricks. "Hold on!" he yelled, begging for Donnie to hear him. "I'll find you! Don't you dare leave us!"

"Leo found Donatello eventually and carried both Casey and Donnie back here. Donnie was breathing but his condition was critical and his body was severely damaged in the explosion. So Donnie kept himself busy with creating himself artificial pieces to rebuild himself. He still had his arms and but his legs were badly damaged. So Donnie created prosthetic limbs and attached them which strengthened his legs so that he could walk again; he was brilliant," April said, sitting down on one of the benches with Donnie, who was sipping a cup of black coffee. "But Donnie couldn't go out on missions anymore because of this and monitored the technology in the base. However, this hurt your brothers a lot. They found it hard to function as team without their know-it-all brother," April smiled at Donnie before her expression turned sad once again. "After that, they drifted further and further apart. Leo and Mikey pretty much live here but really do their own thing but Raph...He lives alone, away from us."

"Then that's that," Donnie slammed his mug down and stood up, placing his hands on the table and looking April in the eyes. "I won't let my future tear my brothers apart from each other. I'm going to find Raphael."
