Feeling strong arm of reassuring safety grasp her body closer to his as they slept. The slight mummer from the television giving off a hue of blue light that spread over the foot of his bed, crawling slowly up their entangled legs to his beautiful green complexion. She turned over to look at his sleep face, with a slight smile from her body brushing up against his. His calloused palm rubbed against her soft skin on her stomach as she turned once more on her side, letting his arm fall around to her back. She dragged her finger tip slowly over his bright skin as she leaned in and kissed his cheek. They circled into a smile for a moment before relaxing back in sleep. She couldn't help but follow his reaction as she snuggled her body back down against the bed, cradling her body even closer against his.

Fiona woke up with a yawn as a smile crossed her face, stretching her arms and legs the length of his bed feeling the slightest bit of soreness ring through her limbs as she did so. She leaned up and bounced herself to turn over to wake him up, beaming smile and ready to shove him against his wall, hard enough to knock Michelangelo out of his comatose like slumber. She turned with a furrowed brow as she ran her hand over the spot he had left on his sheet. They were still warm. She shrugged.

"Probably went down stairs for breakfast." She said bouncing off his bed and looked over at the clock on his nightstand. It read five in the morning and she furrowed her brow. He wouldn't have gotten up this early after what they had to go through the night before, the fighting and then...afterward. He was strong and could indure a lot of phsyical labor, but that would have kept him in bed.

She would have felt him move now that she thought about it. She wasn't a very light sleeper but any movement he would have made on his small bed, ninja or not being that close to him she could have felt it. She crossed her arms looking back towards his bed, thinking he was playing a trick on her. When she got nothing but the wrinkled sheets and bunched up comforter she dropped her arms going over to it.

She leaned down on her knees looking under his bed, finding nothing but a stack of comics and a playboy. She rolled her eyes tossing the playboy in the trash bin by his door.

"Raphael…" She said in a low growl.

Michelangelo felt the comforter get pulled from his body as he groan, rolling onto his plastron. Burring his face into his pillow and wrapping his muscular arms tightly around it trying to fall back to sleep from the excursions his body had went through the night before, he heard her sigh. It was soft, and not that of a sleeping sigh. He could hear the distress behind it and furrowed his brow with a yawn, lifted his head up looking at her over his shoulder as she placed her hands on her hips, looking around his room. She kicked a pile of her clothes around as he turned slowly back to his shell, lifting his hand up to his bare face, rubbing sleep from it slowly.

"What'd you lose babe?" He asked in his husky sleep covered tone as she didn't even look back at him. "Fe." He said a little louder as she still continued to sigh, turning towards the foot of his bed and looking in a closet behind his TV.

She fought back the cords to open the door as she let out a growl getting nothing but his old gear and wires from broken down or old video game consoles. She turned back around as he picked his head up, leaning up on his elbows feeling his eyes narrow a bit.

"Fiona, I did ask you something." He said as she once again ignored him and walked to the door. He growled getting from the bed before she could reach the door and grabbed her wrist. He grasped it hard enough for her body to turn towards him. "Fiona." He said right next to her as she picked her head up a little. He smiled feeling his stomach stop lurching and churning for a moment before she turned back towards his door. She looked right at him, picking her head up slightly to be in his eye level as her face frowned. She pulled away from his grasp as his hand fell like dead weight next to his body. He grabbed her again and without any reaction moved away, walking forward onto the platform that over looked the main living area.

Fiona felt a shiver crawl through her body as she reached for Mikey's door handle. She felt it again, looking back into his room with a single last once over before leaving. She thought maybe he couldn't sleep and went down to the living area to play a video game. He had done that a lot before when she used to stay over.

She heard a soft echo of his voice run through her head as she turned back towards his door. She furrowed her brow taking a step and looking around the platform. Walking over to the railing she looked over it before turning with a sigh and walking down the stairs.

Once she kept going Mikey felt his heart catch in his throat. This couldn't be happening. She had to know he was right there. This was some kind of sick trick. Fiona wasn't one for pranks though, even if she was acting like she was ignoring him she would of at least cracked a slight smile to tell him she was playing. Her sad features breaking across her face told him otherwise. She wasn't playing a trick, she really couldn't see him. He furrowed his brow still walking beside her as she jogged lightly down the stairs. She tilted her head to look over at the couch as she saw it wasn't occupied.

She felt her heart start to beat a little faster, burning like she someone just lit a flame within her. She turned around looking towards the alcove that lead to the dojo. He never went in there unless he needed to train, with his brothers and that wouldn't take place for another hour or so. She sighed and ran towards it anyways.

Mikey watched her run towards the alcove of the dojo and sighed jumping into a run as well and catching up with her. She pushed open the sliding door as she leaned against it, almost sinking like her heart as she saw it was empty.

"No…" She said softly as he looked at her feeling a burning behind his eyes. He reached towards her again as he saw a soft tear graze down her cheek. He lifted his knuckle to catch it before it fell, stopping as he felt nothing. The tear against his skin wasn't wet, or hot. Her cheek wasn't the soft texture he remember, it felt like nothing at all. He growled slamming his hand on the wall beside her as she let her back catch her buckling knees. "Mikey…." She said softly again as he lifted his head towards her, looking down as her body started to slowly slide down the wall.

Jacqueline woke up feeling the heavy arm around her waist weigh her down as she turned to look over her shoulder at him. His snore echoed in her ear as she smirked a little, taking his hand a slowly lifting his large arm from around her waist. He gripped her stomach, pushing her body back tightly against him. She giggle slightly feeling his hand push her waist into his lower plastron.

"Raph…" She said softly as he grunted in repose. "Lemme up."

"Why?" He asked in his gruff low tone, lingering remnants of sleep still attacked. The sound making shivers crawl through her body and self consciously roll her hips into him more. He smiled kissing her bare shoulder, moving her hair out of the way of her neck with his beak and kissing her there. She closed her eyes letting a soft sigh out from the feeling of his warm lips caressing against her sensitive skin, closing together and repeating inches away from the spot he just left. She felt the softest feeling of a smile move over her shoulder from his lips as his strong hand slid its way down stomach, closer to the heat coming from between her thighs. He slid his palm over her hip as he let it rest, squeezing her thick skin. Aside from the warmth swelling inside her body she felt her sister's pain start to pound throughout her head. The tears falling from her sister's eyes onto her soft round cheeks, her heart breaking sadness. Something was wrong.

"Somethin's wrong." She said softly as he furrowed his brow leaning up from her.

"What?"

"Iunno…" She said sitting up and getting from his bed.

"Me?"

"No…" She chuckled, leaning down and kissing his cheek. "Fiona. Somethin' isn't…Iunno, I felt somethin'." She said slipping a shirt over her head.

Jade blinked her heavy eyes as she leaned up from Leonardo's head board that she slumped against all night. Her hand never leaving the place on his chest where she could feel the soft fluttering beat of his heart against her palm. Sitting up her shoulders protested her movement, she ignored the tightening pain. She felt something knock her out of the daze she kept on the flickering candle light against Leo's wall, needing herself to stay awake in case he needed her. Something wasn't right with her little sister, distress, hurt, discomfort. She could feel her eyes burning from the tears that trickled down Fiona's cheek.

Running her hand that lay across her lap over her face to rub away the sore feeling behind her eyes of lack of sleep she pushed herself from Leo's bed. He moved against her letting out a soft sigh as she placed her hand on his cheek, leaning over him leaving a soft peck there. Her soft foot steps made no sound as she opened his door slowly looking into the hall.

Jade walked out onto the platform that looked over the living area as she heard the soft click of a door beside her. She looked over her shoulder as Jacqueline lightly closed Raphael's door giving her a worried glace. Jade shrugged in response as the two eldest made their way down the stairs.

As they got closer to the couch where the television still hummed with a blue light illuminating the ratty old fabric they heard the soft whimper of their sibling. Jade sighed walking over to her as Fiona picked her head up with red, tired eyes. She pushed her black hair out of her face as it stayed there from moistness on her cheeks.

"What happened?" Jade asked softly as she knelt beside her little sister, Jacqueline crouching down in front of her, placing a hand on Fiona's knee for balance.

"Was it Mikey? He do somethin' to you?" Jac asked narrowing her eyes as Fiona nodded her head then shook it.

"No, he didn't do anything. I can't find him." She said softly as Jade looked over at Jac.

"What do you mean you can't find him?" Jade repeated again, slowly tucking Fiona's hair behind her ear in a soothing motion. Fiona shrugged and wiped another tears from her wet cheek.

"I woke up and he wasn't there. I kept feeling this weird feeling that he was around me but, not." She shrugged again. "I…I don't know what happened?" She said putting her head down on her knees that were hugged against her chest.

"Maybe he went topside?" Jac suggested as Jade shrugged.

"Why?" Fiona asked picking her head back up.

"He say anything about a comic coming out today?" Jade asked as Fiona shook her head.

"No, I don't remember a comic coming out today and I think that would be the farthest thing from his mind at the moment…" She said as Jade and Jac looked at her doubtfully. "What? He doesn't always think about that ya know." Fiona said in offense as her sisters stood from Fiona doing the same.

"Alright, so where else could he be?" Jade asked crossing her arms as Fiona shrugged once more.

Mikey leaned next to the wall with a sigh shaking his head as he watched the girl's debate his whereabouts. He tired jumping around throwing things and nothing happened. Fiona noticed a pillow fly through the air at one point and got up from her slump against the wall and noticed Klunk on the couch patting a blanket. She thought it was just her imagination and lack of sleep running away from her in this emotional state.

"Let's wake the guys and tell them to come search topside with us. We'll cover more ground if we take the streets and they take the roofs." Jade said as Jac nodded her head.

"But why would he go topside? He knows better than that, especially if the Foot are out there." Fiona said following her sisters to the stairs as Jade stopped her.

"Maybe but that spray could have done something, making him delusional."

"Yeah more so then he already is." Jac smiled as Jade shook her head at her sister's distasteful joke.

She walked into Leo's room as he sat on the floor at the foot of his bed in lotus position. She smiled, closing his door quietly as she sat next to him placing a hand on his shoulder, letting it slowly slide along his rough textured skin to lay atop his perfectly curved muscle. He turned towards her with a smile as she leaned forward, letting her cheek brush against his as she moved her body closer, holding onto him as her forehead finally rested against his shoulder. He closed his eyes as her soft hair engulfed his senses letting him take in the sweet scent of, running his fingers along the soft strands gripping it in his hands as she leaned up with a worried expression.

"What?" He asked as she sighed. She knew as soon as the faithful words of his littlest brother gone missing he'd fly up in a anger he himself only knew to have. Not letting anyone else see the pain flash through his eyes, heart breaking worry that she knew would take him over in an instant knowing one of his brother's was missing.

She let another slow breath cross her lips as she pressed them together in thought, waiting for the right words to come to her. They never did and she knew she couldn't just let this go. Not for his family's sake, or her sister's. Or herself. She loved Mikey like a little brother now too, after months of knowing him and she couldn't just let him disappear. She cursed herself for letting it happen. Not searching her thoughts long enough for all of them to make sure they were all safe and sound in their beds.

She let her head fall as she could see the reaction of his face at her movement. His eye ridges wrinkling to her head bobbing down, as her soft sighs told him something was wrong. The air was thick with it as they sat in silence. Finally after a moment she lifted her head seeing exactly what she thought to see across his face.

"Mikey's missing." She winced slightly awaiting his reaction as he did nothing for a moment. Sitting there, looking at her as his brows slightly started to crease together. He looked down at his hands before he shot his head up and got to his feet. He quickly grabbed his katanas by his bedside and swung open his door in the swiftest of motions. Before Jade realized it she was sitting on the floor by herself hearing his door slam against it's hinges. She sighed getting to her feet as Leo had already left the room banging on Raphael's door, moving to Donatello's. "Get up! Mikey's missing!" He yelled as he waited for his brother's to emerge from their rooms.

"Guy's I'm not…" Mikey started as Leonardo walked past him. "Leo, I'm not missing! C'mon, you guys have to see me! I'm right, here! I'm right here!" Mikey screamed jumping up and down in front of his eldest brother, shaking his hands before his face. Leonardo stood, arms crossed staring right through him towards the slowly opening doors of the bedrooms.

Donnie rubbed his eyes before placing the purple fabric of his mask over them with a yawn. Lexine walked out behind him trying to smooth out of knotted blonde hair. Raphael slipped his sais in his belt meeting Leo, Jac, Jade and Fiona at the bottom of the stairs as they waited for Donnie and Lex.

"Have we tired his shell cell?" Leo asked as Fiona shook her head.

"Won't do any good, it's on his nightstand." She said with a shrug. Leo shook his head, looking towards Raphael as they both gave each other a nod in approval. Without a word to anyone else the two eldest made their way towards the stairs. Jade and Jacqueline looked behind them at Fiona, Lexine and Donatello before following their red and blue clad boyfriends to the stairs.

Jacqueline ran slightly to catch up with Raphael as he looked over at her for a moment. Jade made long strides behind Leonardo as he stopped short in front of her. She placed her hands on his shell to stop herself from running into him as he turned his head over his shoulder looking past her. She furrowed her brow looking in his direction as she noticed Splinter walking towards the stairwell.

"What is going on my sons?" He asked as he leaned heavily on his walking stick. Leo bowed his head to his Master before taking in a slow breath.

"Michelangelo has gone missing Sensei." He said slowly as Splinter's eyes widened. His head fell and his eyes slowly closed, his ears going flat to his head. "We're going out to look…"

"No Leonardo." Splinter said lifting his head up quickly and reaching out toward his son. "Something is not right. Michelangelo is here, I can feel him."

"Finally…" Mikey said to himself as he leaned against the banister watching the group.

"You have new information about the Foot." Splinter said looking towards Leonardo, letting his gaze slowly cross all his son's faces landing on Donatello and Lexine. She nodded her head as Donnie shrugged.

"Well, he was sleeping."

"I was put to sleep." He corrected as Lexi furrowed her brow to his tone.

"Ye-yeah…I didn't think he needed to be helping me if he didn't feel good." She said eyeing him carefully before turning back towards Splinter.

"What did you find out my dear?" He asked as the group started to slowly walk down the stairs, following Lexine's lead as she walked the elderly rat to the kitchen table.

"The serum that we were trying to figure out, the one that we were watching the Foot create, it seems as through they compressed it to gas…" She said taking a seat next to him as Donnie leaned against the counter next to Raphael and Jacqueline. Jade and Leonardo both standing close to the stairs with their arms still crossed tightly against their bodies.

"I'm totally fine." Raph said crossing his arms as Leo nodded his head.

"Yeah, I don't feel any different." He shrugged, walking a little closer to the conversation.

"You might have not gotten the brunt of it like Donnie and Mikey did." Lexi shrugged as Donnie shook his head.

"Well, that can't be the case because I feel fine too." He said crossing his arms over his chest as Lexi turned her head back towards him as he used the same snappy tone.

"If Mikey's here, where is he?" Jade asked as everyone started to look around the large open room. Splinter stood with his eyes closed as he took in a slow breath.

"Michelangelo has a very strong personality. One that is very hard to ignore. Fear is something that can consume you, your whole being until it is fighting against the current that is your normal self. Few have beaten it, and been better for it. Strong minds and strong hearts are the ones that make it through. Michelangelo is a strong heart and for those around him to not pay him any mind, ignore him, would be a living nightmare."

"So…We can't see him because the fear serum made him invisible?" Jac asked in a tone of disbelief.

"To those who care about him and whom he cares about." Splinter nodded slowly looking over towards the young girl who shifted under his gaze.

"But he can hear and see us?" Jac questioned again.

"This is weird…" Fiona said as Jade sighed putting an arm around her little sister.

"Well how are we going to run tests on him if we can't see him?" Lexi sighed turning towards Donnie as he picked his head up slowly looking towards her. His eyes slowly moved over the group as they all looked at him. He rolled his eyes with an exasperated sigh.

"Why is everyone looking at me? I don't have all the answers! Maybe for once you can figure this out for yourselves." Donnie snapped as Lexi furrowed her brow, watching him storm off to his lab. The door slammed shut as Fiona jumped slightly to the reaction. Michelangelo narrowed his eyes on his older brother as he moved to lean against the table closer to his father. He knew Donnie would be able to figure this out. Donnie always figured out Mikey's problems. Gave him advice, he was the smart one after all while Mikey was free to do what he pleased letting himself not need room to think. Donnie always did that for him, Donnie did that for all of his brothers. Leonardo even couldn't figure out things and looked towards Donnie for help. Now, as everyone looked around at each other with worried, slightly aggervated expressions how were they going to figure this out. Mikey sighed putting his hand to his forehead with a sigh.

"Someone woke up on the wrong side of the shell..." He muttered to himself.

"Whoa…someone woke up on the wrong side of his shell." Raph said arching his brow. Mikey lifted his head up towards Raph with a slight pout.

"Even when he can't see me he steals my material." He sighed letting his head fall against the wooden table with a loud thud.

Leonardo stepped forward with a sigh, walking towards the lab as Lexi held her hand up to stop him.

"No, let me." She said turning towards the closed lab door with a sigh. She walked over towards it feeling the burn of the other's eyes on her as she walked. She placed her hand around the handle as she twisted it as slowly as she could turn her wrist, not wanting to let any sound seep from it.

Opening the lab door she saw him standing with his arms braced on his desk, his head hanging low between his shoulders. The light from the computer shinning over his shaking head as she let the other light from the main room slowly seep out from closing the door behind her. The soft click made his head lift up, kept to the computer screen in front of him.

"I guess storming off isn't enough of a hint." He said in a soft growl as she rolled her eyes. She kept her back towards the door, not wanting to rattle his already shaking up emotions.

"Don…I know this isn't you. Something happened and…"

"Nothing happened! I'm totally fine. I'm sick and tired of everyone always looking towards me for information! I don't have all the answers!" He said turning towards her now as she took a step back against the door. She tired not to look shaken up by his tone, keeping her calm as she started to feel her hands shake from behind her back. He stayed his distance as she kept hers against the door.

"Well, if you don't think you can handle this right now I can…"

"What can you do?" He said crossing his arms with a slight smirk. "You went to MIT, you barely even know our genetic mutant formula, and I was the one that did all the research and mixing for the serum. You got yourself caught by one of Stockman's henchmen, without even knowing he placed a tracking device on you! I mean….Really Lex." He said in a slight chuckle shaking his head.

Lexine narrowed her eyes on him as he turned back towards the computer sitting down at his desk. She knew this wasn't her Donnie saying these things. He was the most caring guy she knew, ever. He wouldn't harm a fly, if he didn't have to.

"I'm capable of more than you think Donatello." She said taking a step away from the door and walking in towards the room. He turned in his chair as she froze again. He smirked as he noticed her whole body tense from his glare landing over her shock covered eyes. Standing from his chair as it slammed hard against the desk behind him, he started walking towards her. She jumped slightly from the noise as he smirked wider.

"Capable? Of what my dear? You barely even make yourself useful with your own family and protecting them. Now, you think that you are able to take on mine as well?" He said as she backed away from him as he walked towards her. She felt her back press hard against the cold bricks of the lab wall as Donnie kept his malicious smirk on his face. She swallowed hard, placing her hands on his chest to keep him from getting too close as he looked down at her soft hands on his green skin. She winced slightly, wanting to move her hands, and duck out of the way.

"No, this is Donnie. He's in there somewhere. His mind is distorted and…"

"Looket you, you're trembling." He scoffed as she clenched her eyes turning her face from his as he leaned down brushing his lips against her cheek. She could feel the warmth of his hands moving down the curve of her side as his breathing washed against her neck. She started feeling her chest raise and fall, hard against his as he pushed his body on her enough to make her shoulders hurt from the pressure of the bricks behind her.

"Don-Donnie…Stop. Please." She said through shuttered words as he pulled back. She felt his body move from her as she opened her eyes slowly looking into his. He furrowed his brow looking at her before cupping her face in his hands.

"Lex…are, are you alright?" He asked softly as she let out a slow breath, wrapping her arms around his shoulders. She pulled away pushing his face against hers as he tensed from the surprise before letting his body relax against her kiss, putting his hands around her waist. She took his hands and pulled him towards the computer as he went willingly.

"Help." She said as he looked up at the screen furrowing his brow at the sight of his DNA.

"When did you take this?"

"Last…night? You don't remember?" She asked pulling a chair beside him as he shook his head. "You don't remember…anything…?" She asked arching a brow as he looked down at his hands then back up at her shaking his head. "Huh…I was wondering why you weren't as gentle as you usually are." She said turning back towards the screen as he furrowed his brow grabbing her hands from clicking the keyboard.

"Wait…what?"

"When we came home last night, I took a blood sample to help figure out what is wrong with you guys. I figured out it was the serum, in compressed gas form and I sent you off to bed. After a few hours of coming up with nothing I went to bed. You woke up and…Well…" She shrugged. He sighed looking back towards the computer.

"Well, let me at least try to figure this out."

"You know Michelangelo was effected as well, right?"

"Mikey? How?"

"He's invisible." She said as he arched a brow turning towards him.

"Wha…Invisible? How?"

"Splinter said something about Mikey having a strong personality and…"

"This biggest fear would to be ignored. Makes sense." Donnie said turning back towards the computer and clicking over files. "There has to be a cure."

"That's what I was trying to figure out but…I just couldn't without you." She sighed putting her head down as he smiled nudging her shoulder with his.

"Don't sweat it Lex, you did an amazing job, for someone who graduated from MIT." He chuckled as he narrowed her eyes punching his arm. Lexi got from her chair as her arm was lit by the screen. Donnie smirked at her watching her arm pass him as she reached up to rub his cheek. He grabbed her wrist moving her forearm into the light as she pressed her lips together to fight back the sound of pain. "What's that?" He asked as she sighed, moving his hand and taking it in hers. She crouched down in front of him as he looked down at her worried, removing it slowly as she kissed his hand.

"You were….aggressive, last night." She shrugged. "It doesn't hurt." She smiled as he leaned down kissing her forehead.

"I'm so sorry." He said grimacing at the mark he had left on her from the night's events. She chuckled leaning up and rubbing his head.

"I didn't even feel it, over the…other thing." She giggled leaning down and kissing his cheek once more. "You work on this. I'll get you some coffee." She said as he nodded his head keeping his eyes on the computer screen. She opened the door slowly as she was soon cornered by Raphael looking at her with a worried look.

"Is he ok?" He asked as she smiled patting his shoulder.

"Uh…Yeah Raph…he's fine." She asked looking towards Jac as she shrugged.

"Alright good." He said in a sigh as she walked over towards Jade taking her sister's arm.

"Was he effected too?" She asked looking towards Leo as he sat at the kitchen table. She shook her head.

"No, he's fine."

"So what was with Don's hissy fit?" Jac asked jumping on the counter as Lexi started a pot of coffee.

"He was effect, his blood has a high amount of the serum in there. He'll most likely snap back into his 'hissy fit' as you so wonderfully put it if someone sets him off."

"So he's Raph?" Fiona asked as she chewed on a piece of pizza. Lexi and Jac both turned towards her with a questionable look as she shrugged. "What?" They both rolled their eyes shaking their head.

"Yeah, but my question is why he did that. It's a fear serum not a turn into an asshole serum." Jac shrugged as Leo shook his head with a chuckle.

"Donnie is really important to this team. He is asked to do a lot of things for us with his knowledge of things that we don't understand, but he does. He knows this, and accepts it as his role in our brotherhood. The worst thing Donnie could ever do in his mind is hurt one of us, one of those whom he cares about intentionally with that brain power of his and his strength." Leonardo said looking up at Jac and Lexi.

"That explains the cornering in his lab." Lexi sighed as Jac furrowed her brow.

"What?"

"He…I was trying to calm him down and he said hurtful thing after hurtful thing and I tried to keep my cool, but he just used my broken demeanor as a weakness on my half. He cornered me and I pleaded with him and I guess he snapped out of it. I don't know if it'll last for as long as we need."

"Well, just snap him out of it again."

"If I can." She sighed looking back towards the lab.

"I'll snap him outta it." Jac said crossing her arms.

"I'm not going to let you hurt him, that's still Donnie, my Donnie. I'm not going to allow you to…"

"Calm down braincia. I'm just sayin' if the time comes around and he corners ya again, I'm not gonna just stand back and let him do it. Maybe if ya like scare him that'll snap him outta it?" Jac shrugged as Lexi sighed again.

"I don't know. It could be a trigger for something to make him that way, something to work up in his blood stream that makes the chemical of the serum react a certain way. If he gets worked up, or…" She sighed against rubbing her forehead. "I have no idea. He's the only one that'll know what's going on."

"What about Frank?" Jade spoke up.
