Kara paced around the living room in her home while thinking of the event that unfolded not too long ago, the memory flowing through her mind, able to remember every detail. She sighed and closed her eyes not sure what to think of the situation at hand.

"Leo kissed me..." She said and looked over seeing his face was blank of all emotion.

"Wait..he what? Kissed you?!" He shouted, standing up anger now showing.

She stood up as well and held her arms out defensively.

"It's not what it sounds like! He-"

"-Of course not! Silly me! There are so many other meanings for the phrase "He kissed you!""

She glared at him, clenching her fists. "If you would let me explain I will tell you he came to me a couple nights ago and said he had feelings for me."

"And what? You let him kiss you?!"

She stomped her foot on the ground, never liking to be interrupted when she was trying to say something and got up to his face making him take a step backwards.

"I told him I had feelings for you, genius! That my heart belongs to you!" She shouted at him making him look at her in shock. She turned around and hugged herself, keeping her head low. "He caught me by surprise, ok? I didn't expect him to do that..I didn't expect him to be there at all. I can't take back what happened but I had to tell you; it felt wrong keeping it in because I didn't want to lose you. I already messed up once.." She could hear him sigh and feel his presence getting closer before he placed his hand on her shoulder.

"I'm going to need some time to think.." He said but before she could turn around he was already gone.

She groaned before falling onto the couch, just sprawled over it and stared up at the ceiling. "I messed up..I'm such a loser.." She pulled the couch pillow to her, hugging it close before moving it over her face.

It had been six days since their argument. The guys would come visit her but Donnie would be absent from the visits.

One night she took Leo aside and told him everything and asked about Donnie, concerned for him.

"He stays locked up in his lab working on this huge project. He doesn't really leave except to grab something to eat or use the restroom but then he goes right back in. He didn't say what it was either, just that it was a surprise. Look, I'm sorry if I messed everything up." He said, rubbing the back of his head.

"It's not your fault-wait-it is, but I don't blame you for expressing your feelings. It's one of the things that makes you human." She said smiling at him before walking out to the balcony wanting to be left alone for a moment, her head low in despair.

"Six days Donnie...when are you going to let me know.." She curled up on her bed, hugging her pillow tightly but blinked hearing her phone go off. She unlocks the screen, squinting her eyes at the bright light and sits up seeing Donnie's picture showing she had received a text message from him.

"Come down to the lair. I have something to show you." It read.

She raised her brow wondering what it could be before responding back. "Ok, on my way." She got out of bed and changed into a T-shirt of her sister's band logo on it, her vest, and shorts with converse. She tugged her cap nervously before walking out the hotel and finding the nearest manhole, jumping in. She followed the directions Donnie texted her and arrived in the abandoned train tracks. Spotting the turtles she waved to them, "Hey guys!" She walks up to Mikey and plops down next to him on one of the old tracks.

"Guess Donnie texted you too?" Leo asked sitting on the walkway, looking down at her. She nodded and glanced over at Mikey, who clearly looked bored.

"Ugh, what's taking so long? Donnie knows I have a short atte-ooh, gum!" He picks up a dirty wad of gum and before he could pop it into his mouth Raph smacks it out of his hands and Kara smacks him across the head, "That's dirty, Mikey. You could get sick!"

Raph placed his hands on his hips and sighed. "Man, this had better be worth it."

As soon as those words were spoken an old looking train car rolls up next to them. The expression on everyone's face: Priceless! The paintjob could use a little work but it looked so cool! She looked over hearing Raph say, "Worth it." and grinned, agreeing with him.

She hears the ding that would be heard in an elevator and it reveals a cool and calm Donnie who leans against the side with a grin on his face. "Soo?"

"You turned Leatherhead's old subway car into this?" Leo asks, voice filled with shock and awe.

"Donnie, have I ever told you how awesome you are?" Raph asked, eyes wide with amazement.

"No, you haven't." Donnie said cooly with a smile on his face.

"Well, I am seriously considering it."

"What'd you call this thing?" Leo asked while Kara and Mikey got a closer look.

"Well," Donnie started, "It's a transaxle multi-armor electromagnetic-"

"-The Shellraiser" Mikey said in a whisper with a grin on his face. Kara blinked able to see fire behind him as he spoke the name. "Woah." She said in awe.

"What?" Donnie asked, looking over at him and spotting Kara with her back turned to him, a small smile on his face that didn't go unnoticed.

"The Shellraiser. It's the perfect name."

Leo and Raph looked at each other, blinking their eyes, before looking back at Mikey. "That is the perfect name." Leo said.

"Of course it is bro. You always underestimate me. Ooh, gum." Mikey said while bending over to pick it up making Kara smack him across the head again. "What did I say earlier?" She said sternly making him drop the gum with a pout.

While the guys filed in to get a look inside she took a step to follow them but quickly moved her foot back not wanting to overstep her boundaries. She smiled at them, hearing their excitement and turned to leave.

"You're not coming in?" She glanced behind her at Donnie hopping out the Shellraiser and walking up to her.

She smiled and tugged the flap of her cap over her eyes. "It seems like it's something you built for you and your brothers. I wouldn't want to get in the way.." She took a step to leave but stopped, hearing him talk. "You know, I think best when I'm working. Helps to keep me from getting distracted." He said, tapping the side of his head before walking behind her and placing his hands on her shoulder to turn her around. "What you said kept repeating in my mind..about your heart belonging to me and..I-I feel the same about you." He blushed pink and reached over moving her cap from her eyes to see her blushing as well.

"You really mean it?"

He nodded his head making her smile before pouncing on him, kissing him on the lips and causing them to fall over. The guys poke their heads out wondering when they were going to be able to test drive it and blinked, seeing Kara kissing Donnie.

Leo smiled, happy to see them at peace while Mikey groaned having betted with Raph about them and losing. "Looks like you're going to be doing my chores for the next month, Mikey." Raph said with a smirk on his face and arms crossed.

Donnie walked in and sat in the back where he pushed a button and everything turned on. "Now, I've assigned everyone to a station based on your individual skill set. I can't be the driver because my station is in the back so-"

"Driver!" The brother's shouted before pushing and shoving their way to the seat trying to get to it first making Kara laugh out loud before recording them fighting like kids.

Donnie smacks his staff to get their attention.

"Leo drives."

"Why?!" Raph and Mikey yell, angry while Leo grins victoriously.

"He's least likely to hit something just for fun"

"True." Raph and Mikey say before going to their own stations leaving Kara to stand where she was. "What, you didn't make passenger seats? Oh well." She said sitting down on Donnie's lap, making him blush. "Guess this will have to do."

"Oooooh~" Raph and Mikey say causing her to grin and stick her tongue out at them while Donnie blushes more.

"So, how do we get this baby going?" Leo asks, his hands on the wheel, excited to drive it. He looks over seeing Donnie's face on the tv, explaining what to do.

"Ok, just ease the throttle forward ever so slow-" Leo does so but causes the Shellraiser to jerk a bit, making Kara hold onto Donnie, but calms down as they begin to move. "Woo! What is powering this thing?!" Raph asks with excitement.

"The Kraang Powercell we got from Leatherhead."

"I thought you said that was dangerous like the Kraang could track it." Leo said on the screen, looking at him.

"That's why I put it under a lead glass shield. Now I can regulate the output and prevent the Kraang from tracking it's signal." Donnie said leaning back with a confident smile while Kara looked over the controls.

"I hate to interrupt but DEADEND!" Mikey shouts pointing at the screen.

"Uh, D-Donnie, how do I stop this thing?" Leo asks, looking behind him at Donnie. He pops up on the screen.

"Don't."

"What?!"

"Trust me!" He yells Kara staring at the ever growing closer wall, clenching her fists feeling nervous while looking over noticing Donnie was acting calm. Having a feeling he knew something they didn't she closed her eyes to calm herself trusting in him.

Donnie pushes a button and suddenly the wall lifts up like a garage door and the Shellraiser flies out from the tracks and lands on the street with wheels.

Kara's eyes pop out, her mouth hanging open at what just happened.

"Donnie! You're awesome!" She heard Raph yell as they drove through the streets unnoticed by anyone around them.

"Does this thing have a stereo?" Mikey asked looking over at Donnie. Kara was leaning against Donnie, now sitting on the floor, watching the scenery go by seeing a handful of people every now and then.

"What good would this thing be without some tunes." She flinched hearing classical music and gave him a pouty glare.

"Are you serious?" Raph said looking at him.

"Check out the second one." He said pushing another button and heavy metal started playing. Kara grinned, nodding her head in approval even though she was more of a techno, remix type of girl. She smiled watching the guys get into the music and really show their age, which she didn't mind, till she started sliding side to side while the guys dangled by the wires. She shrugged and waved her hands in the air while continuing to slide. "Weee."

After turning a corner Raph opened the top to get a better view, she crawling near him and started tickling his feet making him laugh. "M-Mikey, is that you?! Haha, stop it!" She giggled and tickled him a bit more before sliding back behind Donnie so that he wouldn't see it was her. When he wasn't moving she went to see what was up and heard him tap on the side of the Shellraiser, "Leo, pull over!" When he does Kara follows Raph to the front where Leo is and looks at the screen seeing Purple Dragons robbing an electronics store.

"Purple dragons! Oh ho, this night keeps getting better and better!" Leo said with an excited smile.

"Oh yeah, it's like candy for my knuckles." Raph says, popping his knuckles with a grin on his face. "And tonight's Halloween."

"Wait a minute, who's that?" Donnie said pointing at the screen. Kara squints her eyes to try and see who it was but all she saw was a large shadowy figure.

"Excuse me, boys. I believe you forgot to pay for that but don't worry I accept cash, check, or teeth." The figure said, who sounded like a guy, clenching his fist.

"Huh, that was a pretty good line." Leo said. smiling.

The leader of the gang drops whatever he stole and glared at the man. "What're you gonna do? There's one of you and three of us."

"Wanna call a couple friends and make it even?" The man said, jumping down from where he was standing.

"This guy's got guts." Raph said, quite impressed.

"Time to face the wrath of The Pulverizer!"

Mikey started going fanboy, giggling with excitement. "This is gonna be great." She watched the man or, now that she could see him, a kid attack the air weakly.

She burst out laughing. "What'd you think of him now, guys?"

"Or not.." Leo said out loud, watching the screen.

It wasn't till she could hear the sounds of him getting beat that snapped her out of her laughing.

"Oh! The Pulverizer is getting...well, I dunno the word but we gotta help him!"

"How do you like the odds now, Fong?" Leo said, punching his fist against his palm.

Kara watched in the van knowing they could take care of themselves but pouted wanting some action too.

"Woah, the turtles!" The Pulverizer shouted with a smile.

"How does he know who we-" Donnie didn't get a chance to finish for Fong did a cheap shot and punched him while he wasn't looking. She glared, her shoulders tensing up ready to jump out and beat the lip hair off him but breathed in knowing they could handle it and waited patiently noticing Fong fleeing the scene with the stolen goods. Mikey almost had him but the Pulverizer got in the way.

"I got 'em guys!" She shouted, jumping out the Shellraiser but heard police sirens nearby.

"No time for that. Cops." Leo said jumping into the Shellraiser.

She groaned but spun around and stepped back inside overhearing the Pulverizer trying to hang out with the guys but Raph handled that by shutting the door on him. She yawned softly and sat back on Donnie's lap, laying her head against his shoulder to take a quick nap on their way back to the lair.

He looked down at her and smiled softly gently rubbing her back before turning the tunes back on. He went to change the station but she stayed asleep so he left it alone unaware of the screaming outside.

"You guys hear something?" Leo asked unsure if he was hearing anything other than the music.

Stopping in front of the lair Donnie gently shakes her awake before helping her to her feet and leading her out of the Shellraiser to get some sleep but blinks, seeing the Pulverizer on the ground.

"Guys, we got a problem!" He goes over to the Pulverizer and helps him sit up. "Are you ok?"

"Uh, sure...uh..y-you can survive with just one kidney, right?"

Kara moves out of the way, yawning while trying to wake herself up and looks over hearing Raph speak.

"Great, first this doofus gets in the way of a good Purple Dragon beat down and now he knows where our lair is?"

"Oh, no problem, I blacked out most of the way here.." He said looking ready to pass out once more.

"How do you even know we exist?" Donnie asked standing beside his brothers.

"Oh, I saw you months ago." He said recreating his flashback just as Kara hopped off out of the Shellraiser. Pulverizer's eyes widened upon staring at her. "Woah, I don't remember seeing her though. You would be an idiot not to remember her.." She blinked and looked over at him and chuckled while placing her hands on her hips. "Easy there, Romeo. I'm already taken." She said giving Donnie a playful wink before walking into the lair to find a place to sleep while the guys took care of the situation.

After her much needed nap Kara was helping Donnie with the Shellraiser, handing him tools and whatnot but was also watching the Pulverizer play with Donnie's staff like a little kid.

"Put that down." Donnie said not looking up from his work.

"No, no, wait, watch this move!" Pulverizer said spinning, well trying to spin the staff.

"What are you? A band geek? Put that down." Kara said getting a bit annoyed with his antics. She watched the staff go flying towards Donnie who caught it with ease without even looking, which impressed her by the way. "Look, I'm busy here." He said, lifting his goggles above his head and sighed heavily before jumping down in front of him. "If you must play with the staff, and apparently, you must. Try this." He said demonstrating a move.

She leaned forward, watching and smiled at the way he was teaching the Pulverizer but when she saw the seriousness in his eyes she jumped down while he tried to tell him what being a hero was. She placed her hand on Donnie's shoulder and smiled. "I got this..but I don't want you to see this so please, close your eyes." She said with a soft smile before walking in between the two and glanced back at Donnie in time to see him turn around. She nodded and looked at the Pulverizer. "What you see in the movies or read in comic books..it's not the same. With being a hero comes responsibility...and danger." She lifted up her shirt to show her stomach where three large scars were from where the Shredder stabbed her with. "Being a hero..it doesn't come easy and it doesn't come fast. If that's how you want to do it then you might as well give up now, go home, and forget you ever saw any of this or you'll wind up dead." She said, glaring at him. "But if you want to give it a try then we'll help you." She lowered her shirt not knowing Donnie took a peek and saw the scars on her back, the memory flashing back to where she almost died by Shredder. He squeezed his eyes shut to get rid of the memory but blinked hearing her say "we'll".

Donnie walked up to her and noticed she was still glaring at Pulverizer but he was too excited about wanting to learn to notice. The corner of her mouth twitched. "He's not taking this seriously! The Pu...gah, I'm calling him P! All of this stuff is going over P's head! He doesn't know what he's getting himself into...that'll be his fallout..wish he'd take off that stupid costume. It's degrading to all reptilians.."

While Donnie taught him the basics of using a weapon, she helped him with more of the hand-to-hand combat; the perfect form, despite his um..size, staying limber, all of that jazz but the more she was around him the more irritated she became of him. It was obvious he wasn't taking the training seriously. He just wanted to go fight crime and yada yada. She was too busy yelling in her thoughts to see him rolling into Master Splinter's room till Donnie yelled. "No, stop! You're heading for-" She blinked back to reality hearing a crash and looked over hearing him say "Splinter's room."

"Uh oh...crash+Splinter's room=baaad." She thought hearing Master Splinter calling out to Donnie while walking out of his room holding P like a cat. "Does this belong to you?"

"Sensei, Pulverizer. Pulverizer, Sensei." Donnie said, introducing them.

"Pleased to meet you." P said before whispering to Donnie "Does he know he's a rat?" Making Kara's eye twitch but smiled as Master Splinter dropped him. "He knows."

Donnie explained the situation to Master Splinter and Kara joined in, letting him know she was helping him.
"Yeah, and they're doing a great job. Check this out!" He said demonstrating the moves she taught him and smacked her forehead, feeling Master Splinter's eyes on her.

"Apparently you have not taught him shame. May I speak with you two for a moment?"

Kara nodded, bowing her head. "Yes, Master."

"Hai, Sensei." Donnie said following Master Splinter away from P with Kara.

"Donatello, Kara, he has no business learning our art. He is..." He looks back at P, who waves at them. "A doofus."

"Hai, Sensei but he's going to put himself at risk no matter what I do so I just want to teach him enough so he doesn't get creamed."
"I, as well, Master. You are correct, he is a doofus." She smiled, finding it funny to hear Master Splinter say that word but shook the thought away to focus at what is at hand. "I have shown him the dangers of what are to come if he continues with this but his mind is clouded with the thoughts of crime fighting. We just want to prepare him for what would happen in the future.."

"You may, but, if you two train him then you two are responsible for whatever happens." She nods and before she could say anything she hears the sound of something getting sliced and looks over seeing P struggling to get a spear unstuck from the door. Her face fell in embarrassment watching him and she smacked her forehead again.

"Good luck." Master Splinter said placing his hands on her and Donnie's shoulder.

She was watching P fail at attempting a maneuver that unbalances the opponent then brings them down. She was playing on Donnie's T-phone liking his games better than hers when she looked up seeing Donnie had, finally, fallen over till she looked back down at the T-phone when it started to ring. She answered it immediately hearing Mikey's voice, "DONNIE! WE NEED HELP!"
"Woah, slow down there, Mikey!" She said now rubbing her deaf ear.
"Oh, hey Kara. Could you hand the phone to Donnie, please?" He said in a sweet voice. She smiled and once Donnie was on his feet she tossed it to him he catching it with ease.

"Donatello."

"DONNIE! WE NEED HELP! RAPH HAS BEEN BITTEN BY A GIANT POSIONOUS ROBOTIC FISH!"

"That's not possible. If he was bitten then its venom; not poison."

"Interesting, interesting, GET OVER HERE!"

"Wow, I could hear him over here...well at least with my good ear."

After gathering his medical supplies, Donnie goes to climb into the Shellraiser after Kara but stops and looks at P. "Hey, do you know how to drive?"

"Keh, are you kidding? I've been driving an ice cream truck all summer." He said running towards the Shellraiser, ready for some action.

-In the Shellraiser-

Kara yelled, pointing at the screen while telling him to avoid people, cars, lightposts, mailboxes while flying all over the place, slamming into the sides and falling to the floor. She glared over at Donnie really wishing he had at least one passenger seat before climbing onto Raph's chair and holding on for dear life while Donnie asked Mikey to describe Raph's symptoms so he could create an antidote.

"Almost there." She heard Donnie say but also heard the alarm and knew something was blocking their path.

"The road's blocked, we gotta go around." P said reaching for a button but Donnie stopped him, walking up behind him.

"There's no time to go around you gotta jump it"

"What?!"

"You wanna be a hero? Jump it!"

"Y-yeah..about that..hero thing.."

"Jump! It!" Donnie said, taking over the wheel while she holds onto whatever was closest to her for dear life as they slam through the wall. Kara saw a mutant fish with robot legs and readied the canon, firing garbage at it.

When it was clear Donnie rushed to Raph's side with P right behind him. She went to follow but stopped, noticing a crack in the lead shield protecting the powercell. "..That can't be good.."

As a precaution she put on her gloves, carrying them with her at all times, and rushed out to see Donnie injecting the antidote into Raph making her shudder.

"That was awesome! We saved him!" P shouted with excitement. She glared at him ready to say something to him but Donnie beat her to it.

"WE saved him?! You wanted to stop and sell ice cream! If we didn't jump and smash through that wall!"

She saw Mikey looking her way and turned around remembering the Shellraiser. "Uh, Donnie? Is the Shellraiser suppose to do that?" He asked as pink lines of electricity surged through the Shellraiser.

"It's cracked. Oh, this is bad. The Kraang can detect that energy signature. We got to get back underground before they come looking for the powercell!"

They rushed through the streets trying to get back to the lair but it was too late; Surrounded front, back, and above. Raph dealt with the ones from behind while Donnie and Mikey handled the ones from above, hearing him shout. "They can fly!"

Soon, they crashed into a wall and knew it would be a battle on foot. While Kara and P watched from the screens everything went dark and she turned around seeing a Kraang droid with the powercell. She glared and went to charge it but P got in her way and was pushed back. "Stay out of this, P!"

"Oh, no you don't!" He shouted going after it.

She yelled in frustration before following after him. While he tried to do the maneuver Donnie taught him she jumped over him, slamming her fist into the Kraang droids face and grabbed the powercell before it fell to the ground next to the droid. She pulled P up next to her and handed him the powercell. "Take this to the guys, now! Don't do anything else but that, understand?! I'll take care of these droids." She charged and did a jump spin kick, knocking one to the ground and punched the other one in the face, digging the spikes into its face causing it to malfunction.

She turned around and saw two had cornered P and taken the powercell from him and as she charged to help him they tossed him at her making her fall back.

"No...No!" She yelled in anger, shoving P out of the way as she ran towards the helicopter after the one with the powercell as it entered into the helicopter, watching it fly off. All she could think about was Leatherhead's words in trusting them with it. She clenched her fist and glared over at P who was helped up by Donnie. "Oh man, looks like I mucked everything up, didn't I?"

"Mucked up...mucked up?! That's not the word I would use but this is worse! Why couldn't you stay behind like I said? Why did you have to go play hero?! You could of died! Does that not matter to you?! That thing was entrusted to us by a good friend! He believed we could protect it and now it's gone! But hey, you got to be part of the gang!" She felt angry tears in her eyes and she kicked a trashcan across the street before running off, wanting some time alone.

She was sitting on the ledge of a random building one leg dangling over the side and one close to her chest with her arm over it laying her head against it staring into nothing just letting her mind wander. "I know I overreacted back there.." She said sensing the presence of the brothers as they walked up to her, sitting around her. "But..he's just a kid way in over his head..I tried scaring him.." She said as she glanced down at her stomach, showing them the scars that they all know too well. "I just hope he learns before something worse happens to him." Donnie pulled her into a hug making her smile while the others give her a group hug making her smile brighter. "Okay, guys. How're we going to get the Shellraiser home?"

The brothers were pushing the Shellraiser through the abandoned traintracks while Kara steered

"Are you sure the parking break isn't on?" Raph yelled for her to hear.

She groaned, annoyed and shouted back. "For the hundreth time, yes!...Oh wait.." She pulled it and poked her head out through the door, hearing the "Da-Ding!" sound. "Okay, try it now." She said as the Shellraiser started rolling a bit on its own.

"Kara!" They all shouted making her blush in embarrassment, rubbing the back of her head. "Tee-hee."
