The floor was absolutely littered with busted kraang droids and messy aliens. Donatello stared at the console and the screen before him. He was in the unusual position of not knowing his way around the technology he was looking at. Everything was pink and blue and in characters that he couldn't understand or find a way to decipher.

"How's it going Donnie?" Leo called over his shoulder. All of them were standing guard at the doors. Every so often a group of droids were coming up that they would have to fight. No one knew how many there were, but they figured more would come as Donnie began to hack the Technodrome's systems.

"It isn't going at all yet Leo. It's all in kraang language and I can't understand it," Donnie called back the frustration showing in his voice.

"Is there a button that translates it?" Mikey asked. At first Donnie was going to give him a quick lashing about how this wasn't a comic book, but then he thought about it.

"You know what Mikey, that might not be such a bad idea," Donnie said as he started to search for something that would help him translate the language.

He searched everywhere, being careful not to accidentally set something off. He kneeled down to find a button just underneath the console. He closed his eyes then took the chance to press it. Flinching, he was surprised and relieved to see a panel slide out with multiple lights, buttons, and a small touchscreen next to them. Tentatively he touched the screen and images of planets popped up. He didn't recognize many of the ones he saw, assuming they were from some other part of the galaxy in another solar system.

It took him several minutes, plus a break in order to help fight off a particularly large group of kraang droids that came through the 'elevator' doors. He was just about to give up when he came across the planet Mercury, then Mars, then Earth. He hesitated but really anything was worth a shot at this point. With a shaky finger he touched the image of Earth, and like magic the characters on the screens and consoles became an Earth based language. It was Russian. Donnie chuckled a little at this. It was only half turtle luck at this point. He looked at the image of Earth again this time touching North America and everything turned to English.

'System Ready'

They all heard it boom over their heads.

"Big D does it again bruh!" Mikey whooped as another group of kraang came to interrupt them.

"Don't celebrate yet Mikey. You guys gotta keep them off me until I can figure out how to shut this thing down or destroy it," Donnie said as he frantically tried to figure out how to hack the computer.

Maxine was glued to the television. A horrid monstrosity was dealing death and destruction along the city streets. The news helicopters were trying to film it, but wouldn't get too close for fear of being shot. She knew Raphael and his brothers and friends were there dealing with it.

The sound of the shower died in the bathroom. A few minutes later Asha emerged with nothing but a large towel wrapped around her. Her eyes were downcast and it looked like she could use another round of sleep. Maxine grabbed the remote but felt Asha's hand stop her. She sat down in the recliner with a plop. Maxine looked at her friend worriedly.

"Asha you can't keep torturing yourself like this," Maxine said as she sat back on the couch, tossing the remote down beside her for good measure.

"There's an alien invasion happening, and you don't want to see what's going on?" Asha said. She never looked at Maxine and her voice was hollow. It hurt Max to see her friend without any of her usual verve.

"They'll make it out," Max tried to comfort. Asha simply kept watching the screen.

"They need to move it to the water. That might buy a little time," Asha said with that same monotone. She thought of Donnie. He would have already thought of that.

Max's eyes flickered to the screen then back at Asha. She could see that resolve forming in Asha's eyes. Her body tensed as she subconsciously leaned forward more and more in her seat.

"No." Max said sternly. Asha's head snapped her way, then she sat back sheepishly.

"I know you want to be out there, but…"

"No Max, I don't want to be out there. I want them to come back. I want Donnie to come home."

It was frustrating to the utmost. Every single time he tried to interface with the stupid kraang computer it switched back to kraang language. He would have to remedy this and quickly. Donatello reached for the pack on his back bringing his keyboard around along with a small contraption to hook up to it. He instantly thought of Asha when he held these items. He was so out of it when he realized so many things were stolen from him when they got captured. It was Asha that had given him a wad of cash to replace most of those items, and replace them he did. Of course he had to modify most of it to do what he needed it to do, but still. He would be seriously up the creek without a paddle had it not been for her generosity, and this was before they were a couple.

The new keyboard was wireless and he was so hoping that wouldn't be a problem. He switched it on and connected it to his wrist scan with the kraang settings. He kicked himself mentally for not doing this before. It didn't retranslate any of the things onscreen, but he didn't need that anymore. On the large monitor above him, equations appeared and disappeared, remaining there only for a few seconds. He watched it for a while angry that he couldn't solve them before they went away, until he realized they were simply cycling through. He took a deep breath and got into position.

There was no seat here big enough to accommodate his size, so Donnie sat on the floor facing the screen, keyboard on his lap and pink equations reflecting off his thick lenses. This calmed him amid all the chaos. Numbers, variables, solving problems. All these were a balm to his ever-calculating mind. The need and opportunity to solve these mathematical problems transported him unexpectedly to his personal brand of happy place. He breathed deeply through his nostrils and pushed his glasses up on the blunt bridge of his nose.

On the screen, not only were the equations cycling back and forth, but they were accompanied by pictures. He assumed the solution to the problems would give access to the various parts of the Technodrome depicted. His tongue found its familiar spot in the corner of his mouth as he set to work.

Suddenly the machine lurched to one side setting off a ton of alarms. They couldn't be sure but it felt like it was…

"Turning around. I think this thing is turning around guys," Leo called out to them. "Everybody hold on to something. I got a feeling this won't be smooth."

Ichiro and the rest of the ninja had done enough to stop the treads on one side, causing the behemoth to drag and start turning around. Luckily it was headed towards the water. The military had sent every tank, chopper, and fighter plane at it with no effect. The Technodrome's shields were too strong. However, being only able to deflect firepower left it open to what Karai could only think of as 'manual attacks'.

Her ninjas never surfaced from the tread area completely. She saw them make their way to the other side. Meanwhile she, Slash, Rockwell, and Leatherhead had made as much progress as to be expected. They had managed to disable two more guns, but fatigue was starting to set in for Karai. Leatherhead had offered to carry her on his back whenever they had to climb, and she hadn't the strength to refuse.

"We are going to go to the other side and take out the weapons there. Hopefully the turtles will have found a way to get rid of this thing once and for all," Leatherhead told her sensing her exhaustion and her worry. She couldn't manage more than a nod.

Rockwell made his way over to his friends.

"I need to get inside and assist the turtle who fancies himself a genius. He will not know how to decipher the kraang language in order to bypass the security and interface with the systems computers," he said as he sped off in the direction of the only entrance.

Slash and Leatherhead nodded as they continued their own objective of the guns.

Rockwell made quick work of the incoming kraang droids as he found his way to the control center. He almost got stabbed by a pair of sai before they realized it was friend and not foe. With no greeting he leaped over them and swung his way via the ceiling wires to where Donatello was seated, working on the last of the equations.

"You will need my help to bypass the kraang security reptile," Rockwell said, getting ready to take over for Donnie, who only gave him a reproachful look. He pushed his glasses up once again, stiffly this time before he spoke.

"That's already been done," he said. "Monkey brains," he muttered under his breath afterwards, putting his head down and accessing the trans-dimensional portal.

"I heard that turtle," Rockwell said, giving Donnie his own sharp look before staring at the progress Donnie had made. "It seems you have activated the portal. This is excellent, however you must realize that once it has been set it cannot be undone. We will also have a very limited time to vacate the premises afterwards."

"This is where I may need your help Rockwell. I need to set it to go back to Dimension X," Donnie said rising to his feet, the image of the portal blinking green on the screen above.

"Here, allow me to handle this," Rockwell said moving over to the console. His fingers flew over the controls, and in a matter of seconds he had the portal set. A counter took up the entire monitor.

"I can't read these numbers, how much time do we have Rockwell?" Donnie asked, eyes large behind his glasses.

"Exactly four minutes and thirty-six seconds," he said. He telepathically sent this warning out to his friends on the hull.

"Karai, we have to get off of this thing. Rockwell says it will be destroyed in less than five minutes," Leatherhead told her as he started to descend much more quickly than he climbed.

As they got closer to the bottom, she signaled to her ninja's to abandon ship. She was pleased to see that more than half of them were still alive. Her mind immediately turned to Leonardo. She had to make sure he got out alive. Before they had climbed down she saw that they were almost on the docks. The machine lurched badly as the concrete began to give way underneath it. The tanks had followed it, despite several of them being destroyed by the thing's guns. At first no one was worried about it, until one of the tank's munitions actually hit the Technodrome.

Leatherhead's eyes widened as much as they could as he and Slash held on for dear life. Karai held on to Leatherheads scales, cutting her hands in the process.

"Whatever those turtles and Rockwell did it took out the shields, so we gotta blow this joint," Slash yelled as he took off down the side.

"Hold on," Leatherhead called to Karai as he too went swiftly down.

Inside the Technodrome Donnie just stood at the control panel staring. Splinter and Leo came over to him, panic and relief in their eyes.

"What's going on Donnie? Come on let's get out of here!" Leo yelled, pulling Donnie, but his brother wouldn't budge. He just pointed at the screen that was now cycling through four views. First, it was showing what was happening outside like a large window. Secondly, it was showing the escape pods that were now being deployed, thirdly it was showing the damage that the Technodrome was taking, and the fourth view was the countdown.

"We need to get to the escape pods," he said simply, turning his attention back to the controls and readying the pods.

Just then they all fell to the floor at the terrible lurching of the alien warship. Then they felt several more aftershocks, as outside the military realized the machine could now be hit and possibly destroyed.

"What the hell was that?" Raph and Casey screamed.

"We must be getting hit from the outside. We have to go now! Leo, Donnie what's the holdup?!" April shouted not knowing which way to go to get out.

Jolted out of the mesmerizing views on the screens, they all headed to where the escape bay was. It was treacherous getting there as kraang droids were also running around trying to get out, but still managing to fight or simply be in the way. At long last they found themselves within the escape hatch where the remaining pods were.

The Technodrome lurched again and this time it didn't feel the same. They couldn't see it but they could sense it, it had finally fallen into the water. The other vibrations were it being hammered by the military.

"Okay everyone pick a pod and jump in, we have to hustle!" Donnie shouted. They all jumped into one each. Surprisingly they were just big enough inside for the turtles to fit uncomfortably. Donnie secured them all and then his face dropped. There were only six functioning pods, and he was the seventh man.

Outside the mutants and Karai watched in horror as the Technodrome fell into the water. If this had been the bay or one of the rivers it wouldn't have been such a big deal, but this was the Atlantic Ocean. It wasn't even the beach where the land sloped gently into the water, but the industrial part of the docks where large vessels like barges and ocean liner's dropped anchor. The dropoff here was drastic and came up quickly. Already the warship was more than half submerged. Not to mention the constant barrage of heavy firepower from both the tanks on the ground and the gunships in the air were pushing it further in.

No one had seen the turtles come out. Kraang were trying to escape via escape pods but they had been shot out of the sky. A new fear gripped Karai as she thought perhaps the turtles had been in those small ships.

As the military came closer Karai, her ninjas, and the mutants moved to the shadows. They took cover behind the concrete debris and the shipping containers stacked high. Karai watched the water as the Technodrome sunk deeper until it could no longer be seen. No other escape ships had left it, of that she was sure. She thought of her t-phone hoping that it hadn't gotten crushed or lost in the fight. She patted herself but didn't find it. She cursed under her breath as all she could do now was wait.
