Kayla stopped doing her Algebra homework and looked over her shoulder when she heard a knock on the door.
"Yeah?" she called. The door opened and Don peaked his head inside.
"You've been in here all day. How many assignments have you gotten done?" he asked.
Kayla looked back down at the math homework she was currently doing. She'd been working on the same assignment for the past two hours because she couldn't remember how to do anything from that unit. And this was only her fourth assignment of the day.
"This is my fourth." she mumbled quietly. Don walked up and looked over her shoulder at her notebook. He narrowed his eyes.
"That's the quadratic formula, right?" he checked. Kayla thought for a moment before nodding. "You do realize you're doing it wrong."
Kayla looked down at her notebook in dismay. "How am I doing it wrong?" she asked.
"Well, I think you got the 'a' and 'c' mixed up. And the denominator in the formula is supposed to be '2a', not just 'a'." Don explained, pointing out several numbers she had written down.
Kayla blinked a couple times as it sank in. "Oh." she said after a moment, she did somewhat remember the quadratic formula from a few months ago.
Don looked back down at her. "Anyway, I came to tell you that we're leaving for a practice session in a bit. So you need to get ready."
Kayla grimaced. "Great." she grumbled as Don turned and left her room to let her change. She got up and walked over to her drawer, opening it and shifting through her clothes until she found the familiar black, ninjitsu outfit along with her green mask.
When she walked out of the room in her outfit with her mask over her eyes she saw that only Don was waiting for her.
"Where is everyone?" she asked as she approached him.
"They went on ahead, so we're gonna go meet them." he answered. Kayla nodded as she followed him.
She noticed as they raced across a rooftop that Don kept glancing at her and smiling.
"What?" she asked, an annoyed edge to her voice.
"I just haven't seen you wear that since Leo left. I kinda missed it." he admitted as he leapt over an alleyway to the next rooftop.
Kayla didn't know what to say in response to that, so she just kept quiet. It was true that she hadn't worn her ninja outfit since Leo left, she hadn't needed to since Master Splinter forbid them from going topside to fight. She was actually surprised that it still fit her, but she never really thought her brothers would miss her wearing it.
After a few more minutes they leapt onto a fire escape and began climbing up to the roof of a much taller building. Once on the roof Kayla saw Mikey hanging upside down from the ladder of the water tower, Leo was leaning back against the metal bars supporting the water tower, and Raph was sitting on the edge of a skylight with one leg up and the other hanging off the side. Don went to stand near the water tower, but Kayla jumped up onto the skylight to sit next to Raph.
Raph smirked and nodded a greeting to her, which she returned. Then he turned to the others.
"Okay, Leo, I'll bite. Whatta we doin' up here?"
"I told Splinter I'd get this team in shape again."
"Hey, I've been training," Mikey put in as he pulled himself into a sitting position a ladder rung, "since ya left my videogame scores have, like doubled."
"Right, and while you've been playing games, little brother, this Nightwatcher character and his little sidekick have come into the neighborhood like some kinda vigilante showboat, but their days are done." Leo crossed his arms as he looked over the skyline. During his little speech Raph and Kayla couldn't help shaking their heads. Finally, Raph had enough of listening to him.
"Hey, you went AWOL, Leo. And they were the only ones around to pick up the slack." he said as he hopped off the wall, strutting up and getting in Leo's face, "Crime neva' took a break. You did."
Kayla narrowed her eyes, wondering how far this argument would go, but of course Mikey had to speak up.
"I heard Nightwatcher's body turns into a plane, or like a jetpack." he dropped back so he was hanging upside-down again, "Hey, Don, you're so smart; why don't we have jetpacks?"
Don put his bow back behind his shell in his belt and he approached his younger brother. "Yeah, that's good Mikey. I don't even trust you with a drivers license." he turned to his other siblings, "Have you seen the way this guy behaves-"
Don was cut off by a loud, animalistic roar, which also caused Mikey to fall off the ladder and land on his head.
"Whoa." Mikey leapt to his feet and raced to the edge of the rooftop, followed closely by his brothers. Kayla leapt off the skylight and followed. "Whoa-ho, someone's cranky." he joked as he pointed to an old construction site where the roars were coming from.
"Okay, Jungle-Boy, grab a vine." Raph joked as he leapt off the side of the building, landing on the cantilever beam. Kayla glanced nervously at Leo before following.
"Raph wait! Splinter told us not to fight!" Leo shouted angrily, but to his dismay Don and Mikey soon followed suit.
"Hehehe, 'Jungle-Boy', good one." Mikey laughed as he leapt off the roof.
Kayla glanced over her shoulder just as Leo finally followed his younger siblings, and she heard him shout, "Alright, but remember, we're only up here for training."
"You know what I always say, 'train by doin', dude'." Mikey said.
Don, who was following behind him, asked, "Mikey, when have you ever said that?"
At this point Raph and Kayla were climbing up the outer support beam, Kayla climbing right behind him.
"Hoo, ya smell dat? It's like a monkey cage up here." Raph yelled back at them.
"Better that than Mikey's room." Kayla joked. Raph smirked back at her over his shoulder.
Just as Raph peaked his head over the side of the floor where the noise was coming from Kayla saw a body being thrown off the building. She managed to squeeze her way past Raph so she was clinging to the edge of the building right next to him.
Inside there was a giant blue-furred gorilla-type animal with a bare, pink chest and feet, fangs, pointed ears, and horns. He was fighting off what appeared to be well over a dozen Foot Ninjas.
"Well, the good news is there's a buncha Foot Ninjas gettin' the snot kicked out of em." Mikey joked.
"Bad news is this thing is gonna run outta body soon." Don added just as a ninja was sent flying right between him and Mikey, causing them to lurch out of the way.
"Yeah, so? You think we should help these guys? I'd rather enjoy the show." Mikey responded as he went back to watching the fight. He then turned to look back at Leo, "Whata ya say, Fearless Leader?"
Before Leo could answer Raph shouted, "I say we stop talkin'!" before rushing into the fight, pulling his sais out of his belt. Kayla glanced guiltily back at Leo before doing the same, followed by Mikey, Don, and lastly Leo.
Once in the fight Raph leapt up and kicked the monster in the chest, Mikey doing the same as Don and Kayla swung their bows to hit the monster. The monster swung his arm, causing Kayla to leap back to avoid it. Mikey wasn't so lucky; getting smacked by the monster's enormous paw, causing him to fly right into Kayla. They were both sent rolling until they finally stopped, ending with Mikey sprawled across Kayla's back. She tried to get up, but he was heavy!
"Mikey, get up!" she shouted in frustration, looking over her shoulder at him.
He groaned in pain, "Ugh, five more minutes, Mommy."
Kayla groaned back. "I am not your mommy! Now get off!" she finally rolled over under him, shoving him off forcefully. Once free of the extra weight she raced back into the fight. She leapt onto the monster's back, but it just threw her off, swinging its arm to hit a beam that hit Mikey as well.
"Little help, Oh Fearless One!" Raph shouted sarcastically. Kayla glanced over just in time to see Leo watching a Foot Ninja in a black cape leap off the building. Then, he turned and leapt into the fight, leaping at full force to slam a kick into the monster's belly, sending the monster plummeting through a hole in the floor.
Raph leapt over a gap to get a better look, shouting, "That was too easy!" Just as he landed the monster leapt back up to roar in his face. Raph got into a fighting stance with his sais ready, "Like I said, too easy!"
The monster swung it's arm, slamming into Raph. He went flying and Kayla had to leap out of the way to keep from being hit by him. He crashed through several steel beams before finally slamming to a halt against one of the outer support beams.
As he slid to the floor he growled, "Bad dog."
At that moment Mikey and Donny slammed into the monster, trying to force it back, but it once again swung it's arms around, knocking Mikey toward where Raph was and knocking Don back towards the edge of another hole in the flooring. Don tried to stop but slid on the steel until he hit the drop-off, hooking his bow staff under one of the beams to save himself.
"Ah! Look at me! Down the elevator!" he shouted.
Kayla raced over and took his free hand, pulling him up to safety.
He sighed in relief. "Thanks, Kay. I owe ya one."
"Pssh. Don't worry about it. You can just call off your little homework deal and we'll be even." she tried.
Don gave her a look. "Nice try." he answered before running back to help their brothers.
Kayla shrugged, "Can't blame a girl for tryin'." she added as she ran after him. However, Leo leapt onto the monster's back, causing it to roll across the floor. It crashed into Mikey, Don, and Kayla; who were all standing by each other. They all rolled off the side of the hole in the floor. Kayla tucked her head in to protect herself as they crashed through about a dozen floors.
Finally they landed with a loud crash on a solid floor, Kayla and her brothers quickly untangled themselves from the monster and moved to stand by Raph, who had been lucky enough to jump instead of crash.
"Ah, this place needed a skylight." he joked as the dust began to clear.
The monster got up and roared as it slowly approached them. Kayla stood slightly behind Donny and Mikey, all five siblings had their weapons out ready to fight. They all slowly stepped back as the monster advanced. Kayla and Raph looked over their shoulders. Behind them was a huge drop-off and below it was jagged stones and pipes that would most certainly make turtle kabobs if they landed on them. Mikey and Don looked back when they bumped into Kayla, noticing why they stopped.
"This is why we need jetpacks." Mikey stated.
"Okay, anymore bright ideas?" Don demanded.
"How 'bout this?" Mikey suggested before he latched onto Donny as they both screamed in fear.
The monster took another thundering step towards them, causing loose brick to fall from the flooring above them and land on top of the five siblings.
Kayla groaned as she tried to push some of the rock off her, but she was pinned on her belly, hundreds of pounds of brickwork on her back.
"When this is over, I'm totally calling the architect." Mikey grumbled, his voice muffled by all the rubble.
"Good for you." Kayla grumbled sarcastically, "At least you guys have SHELLS!"
"Will ya both shut up and push already?" Raph shouted.
"Alright, on the count of three, we all push." Leo spoke. Normally, Kayla wouldn't be up for obeying him, but she couldn't breathe! "One, two, three!"
Kayla heaved upward, almost doing a push-up to force the weight up. She could hear her brothers grunting with the effort.
Finally, they managed to burst free, throwing the rubble in all directions. Once free, they raced to the edge of the building. The monster was nowhere in sight.
"How did something that big just disappear? I-It doesn't-" Don stopped when they all heard the sound of approaching police sirens. "Uh-oh."
"Dude, it's the cops." Mikey added unnecessarily as they all took off running, Raph following last. They leapt off the building, Raph and Kayla bouncing off the hood of a car to soften the landing. Kayla raced to the manhole, which Don was holding the cover up, and was about to leapt down when Leo called from beside her.
"Raph." she looked over her shoulder and saw him staring down the street. Leo nudged her and she took that as a hint, so she jumped down into the sewer as Leo shouted louder, "Raph!"
Kayla moved away from the manhole just as Leo leapt down after her, followed by Raph and finally Don, who let the manhole cover drop after him.
Kayla heard the police cars drive over the street just after that, and Mikey peaked out of the manhole when it was safe.
"Oh yeah, the turtles are back, dudes! I give us a 10 for style, an 8 for skill, and a…2 for stealth."
