Broken Promises

"Now that you're on board with our plan, we'll need to get started right away." April stated as she sat a large rolled up paper on the table. "These are the blue prints Donnie left behind for the portal. We've gotten done as most as we can, now it's time to transfer the portal Donnie's already built from his lab to here to finish it. Your job is to lead Stockman, Angel and her team back to the lair to retrieve it." She told Mikey.

"Why does Stockman have to come?" Mikey asked, his eyes narrowing at Baxter.

"Because someone has to make sure you dimwits deliver that device carefully. This portal could help change the fate of our world so it needs to be handled with extreme care." Stockman answered.

"I can be careful." Mikey objected as he stood up straight, the handle of his nunchaku bumping against a cup full of pens, knocking it over.

"My point has been proven." Stockman gave him a smug look, only infuriating Mikey more.

"Think you can handle it?"

"With my eyes closed." Mikey responded.

The trip to the lair was mostly silent with the occasional comments of "this way" and "we're almost there". It felt weird leading a group of people to his old home. A home that was made to be kept secret from people like them.

But things were different now. This wasn't his home anymore so there was no need to keep it hidden. Right?

"This is the entrance." Mikey pointed to the caved in entryway of the lair.

"Soldiers, make a path." Angel ordered her group, one of them, stepping forward, placed a device in front of the entry way before hitting a button on the remote in his hand, triggering the device to explode and get rid of the rubble.

They all filed into the lair's main room.

"So this is where you all were hiding all these years. The turtles' infamous lair." Stockman gazed around the lair. "I must say, it's a little disappointing."

"The portal's in here." Mikey shoved past Stockman, ignoring his comment as led them into Donnie's lab, revealing the portal to them.

"There it is." Stockman sighed. "The device that started it all. He really had been building it as an exact replica." He ran his hand along the metal frame. "We'll take it from here, Michelangelo."

A couple of soldiers began unbolting the portal from the ground while another one pulled a familiar looking device from his pocket.

"Is that a kraang teleportation thingy?" Mikey asked.

"Yeah." The solider replied not looking up at him. "What? You actually thought we were going to carry this thing all the way back to HQ?"

Taken aback by the soldier's comment, Mikey left the lab to leave them to their work. He walked over to Angel who was standing in the middle of the main room of the lair, taking in the scene.

"So, you used to live here?" Angel asked, noticing Mikey walking towards her. "This place is a dump!"
"Yeah, well, it didn't look this way 30 years ago." Mikey commented. "This used to be the main room of the lair. It's where we would all hang out, watch TV, play video games." Mikey picked up a deserted, broken, game controller form under its sheet of dust.

"And back here was our bedrooms." Mikey led her further into the lair towards the barracks and to a specific door out of the four of them.

Using the weight of his body to push open the door, Mikey stepped into his old bedroom. The room's lighting was dim due to its only source being from the open door and it had a faint smell of mold. Things that were once on the shelves were scattered on the floor and the ceiling was caving in. Posters were either on the floor or barley hanging off the damp, bricked walls.

It looked exactly the same as when he last saw it.

Mikey watched as both of his brothers walked off into different directions.

"Guys, come back! C'mon, we can fix this!" He shouted after them, not sure which to run too.

Jumping into the Shellraiser, he turned on the ignition and drove in the direction Raph went. Seeing his brother stomp down the tunnels, he pulled the Shellraiser around so it blocked his path.

"Raph, wait!" Mikey jumped in front of him.

"Just leave me alone, Mikey." Raph pushed past him, still rubbing the side of his face.

"Look, I know you're angry, but I'm sure Leo didn't mean it. We should all just go back to the lair and work this out together-"

"What lair, Mikey?" Raph turned around. "Our home is destroyed, there is no lair to go back too."

Mikey's shoulders dropped.

"And that guy back there is not Leo. Not anymore. Leo wouldn't have abandoned us when everything went to shit, he wouldn't blame us for everything that has happened and wouldn't keep abandoning us when we need him the most. That guy back there, he doesn't care about us, not since Donnie died. All he cares about it himself." Raph turned from him again. "He's not our older brother and I'm not sticking around to deal with anymore of his shit."

"So… what then? We're just giving up? After all that we've been through that's it? This is how it ends?" Mikey asked

"Yeah, Mikey, I think it is." Raph replied with a pained look as he watched all hope drain from his little brother's eyes.

"I mean who were we kidding? Without Donnie, we're not a team. We're just a couple of kids way over our heads. And it only took three people to die and for you to lose one of your arms for us to figure that out." Raph admitted, tear welling up in his eyes before he started blinking them away.

"Shredder won and we lost. Our part of the battle is over. We should just move on from this and focus more on surviving in this new world." Raph crossed his arms tightly across his chest before turning his back to Mikey. "I'll see you later, Mikey." He began to continue walking forward.

Mikey toke a step forward, reaching out his hand in an attempt to call out for him but then brought his hand back. Getting back in the Shellraiser, Mikey decided to go look for Leo. He drove in the opposite direction Raph was walking, keeping his eyes peeled for any sign of his oldest brother.

After searching the tunnels for hours, he finally came to terms that his oldest brother was gone. Taking the Shellraiser back to the remains of the lair and put in park and climbed out.

What was he supposed to do now? His brothers were gone, His home was destroyed, and his father was dead. For the first time in his life he was all alone.

Crawling out of the Shellraiser he squeezed through the left over debris to get into the lair. Making his way through he made it back to where the bedroom were. He got under a large slab of cement that was blocking the door to his room and pushed up on it with his back to move it out of the way before going inside. Clearing off his bed, he laid on top of it and sobbed into his pillow, surrounded by his destroyed room.

"Commander." A soldier saluted behind them, taking their attention. "The device has been unbolted from the floor and is ready for transport."

"Great. We'll be there in a minute." Angel responded, having the soldier salute here again before walking back to Donnie's lab. "Well that's all we needed to do here. Are you ready to go or do you need a minute?"

Mikey didn't respond to her question. Instead, he walked past her and back into Donnie's lab. In there he caught sight of Stockman standing in front of Donnie's desk. He was holding up an old Nintendo Gameboy with two whisks attached to the top that Donnie used to track the mutagen canisters looking at it with grief in his eyes.

"What a shame for such a great mind to have to go to waste." Stockman sighed in sorrow.

Mikey's eyes dropped before he turned toward the portal in the middle of the room.

"What are you thinking about?" Angel asked behind him.

"Just… how everything was a lie. How the thing that brought the end of the world was right here in my own home. And the guy I trusted the most built it."

"You know he didn't have a choice, Michelangelo. You heard him say so yourself, it was either build this or put you all at risk."

"But was it worth it? To have the world under Shredder's control? To have everyone's lives ruined? For his life to end just so ours didn't have to?"

"Maybe to him, you guys were his whole world. Maybe he didn't care if the world went to hell as long as you guys were ok." Angel pointed out.

That sounded like Donnie. Always putting the people he loved before himself.

The group of soldiers around the machine began to lift it and carry it through the portal created from the Kraang device the led directly to the HQ.

"You ready to go?" Angel asked him.

Mikey looked around once more.

Maybe Raph was right all those years ago. It was time to let go of the past and focus more on surviving in this new world.

It was time to move on.

"Yeah, I'm ready." Taking a final glance, Mikey followed Angel through the portal.

Far on the other side of the city a once abandoned church that was home to the Foot soldiers was expanded twice its size to become Shredder's fortress. A castle to his empire. Foot soldiers were heavily stationed around the perimeter to keep any unwanted guests from entering. Inside, in one of the rooms was a surveillance room where Shredder kept a close watch on his city and all of his slaves. At the moment, the soldiers were occupied with a continuous signal from a once dead location. Taking a tablet with the signal on it, one of the soldiers presented it to his master.

"Our sensors in the sewer systems have been picking up activity in this location multiple times in the past couple weeks." He reported as he bowed before her throne.

The woman leaned forward in her throne to take the tablet from the soldier. Seeing where the signal was coming from made her raise a brow.

"The older subway station under Manhattan, huh? That used to be the lair of the turtles." She commented. "Send soldiers to patrol that area. Anyone found down there sticking their noses where it doesn't belong, have them brought directly to me."
