It hadn't took a day for Ginjo to be found, much to many of the Espadas disappointment who wanted more time to 'play'; except for one. Grimmjow did leave to go to Karakura town, but he didn't try looking for the substitute shinigami. He spent his time roaming the streets in front of shops. He knew that if he didn't leave Hueco Mundo that he would have a problem with Aizen and that was the last person he felt like dealing with; So he just wandered around the town. He tried to get his mind off of the annoyance that was his Zanpakuto but it was hard to do when the spirit made his very bones restless.

Why was he the only one that went through this? Why not the bastard Nnoitra? Or maybe even Ulquiorra?

The growl that reverberated through his body made his hair stand on end, mostly due to the fact that it was involuntary on his part. It seemed that his spirit didn't like the espada either.

Placing his hands in his pockets, he tried to ignore the baggy that dangled from his wrist as he made his way towards his room. By Kami, if anyone saw what he had, he would have to commit murder to a fellow espada, and then suicide on himself. He was already ashamed of what he bought, he didn't need anyone to rub the salt in the already open wound. He wanted to blame his damn zanpakuto spirit for him even 'buying' it in the first place.

He tossed the small baggy on the end of his mattress with a scowl as half the object poked out from the opening of the plastic. Reluctantly, he pulled the bag away to stare at the offending object that had wounded his pride as the Sexta Espada. What in the hell was he suppose to do with it now? If anyone walked in to see the damn thing...

Grimmjow scooped it up into his hand. The object that could be the downfall of his reputation? It was just a simple plushie with beady blue eyes... and orange fur. Yes, this was indefinitely the spirits fault.

Grimmjow scrunched up his nose as he made his way across the room to the small bathroom. No one ever had a reason to go in his bathroom, so he saw it logical to place the plushie there. He wasn't certain what he was going to do with the damn fox toy but for now, it was gonna stay on the sink.

Orange. Mine!

He rolled his eyes with a snort at how proud the stupid panther spirit seemed to be. He had spent centuries listening to the idiot rant about finding and protecting 'orange', he refused to believe the overgrown cat was talking about a stuffed child's toy.

A knock at the door had him flinching before quickly tossing a towel over the back of the sink, effectively hiding the nuisance to his pride.

"What the hell do you want?"

The snarl that rumbled inside his throat made him pause. He wanted to pin that action on his zanpakuto, but he would only be lying to himself; and while Grimmjow was many things, he was never a liar. The snarls and growls that had been escaping his lips were becoming very frequent... the hiss that happened once was embarrassing.

"Aizen-sama has called for a meeting in twenty minutes."

Grimmjow swallowed the hiss rising in his throat at the sound of Ulquiorra's voice. He didn't know what it was, but something about the emotionless man rubbed him the wrong way.

His zanpakuto had the issue of muttering a word quietly every time Grimmjow came across the kiss-ass-servant. It was always said too quietly for the blue haired man to hear, but he wanted to assume it was some type of insult.

Being an ex-captain of soul society and a father was never suppose to associate with each other; Aizen had made his mind up on that several years ago. His joji was too naive to witness half of the things a Society Captain did to 'protect' humanity; It was one of the several reasons why he kept her hidden away from the world. Being around her naturally bubbly personality was like a breath of fresh air and a comforting reassurance not everyone in the world was complete assholes; although, Aizen was sure that his Joji was one of a kind and no one else came close to her.

All these years, everything worked smoothly together...

Until the asshole that was kneeling at Aizen's feet decided to royally fuck up the entire idea of keeping his titles separate; let's not add to the fact his Joji was injured in bed just a few doors down from the large room everyone occupied at the moment.

If it wasn't for the fact that the rogue Captain wanted to make an example out of the Substitute Soul reaper, Aizen was certain he wouldn't be able to hold his mask of patience as he waited for Ulquiorra to retrieve the blue-haired espada from his room. That was another thing. Grimmjow seemed to be in need of a reminder of the hierarchy lately; it had not slipped by Aizen's eyes for a moment of the man's absence. Gin had reported that the espada was showing strange behavior that was unlike his typical personality; moody, not showing up to meetings, and displaying several examples of wild animal tendencies. Aizen didn't have time to figure out the man's problem as he had his own to fix.

"What the hell do you bastards want?"

Aizen didn't spare Ginjo the action of even blinking as he glared down his nose. It should have been a little amusing to Aizen in some part of his mind that the soul reaper managed to make him lose his reign over his own emotions; he had thought he was above such petty actions of glaring and showing just how much something affected him. Apparently, he still needed to work on his control.

"It's not like I hunt fuckers like you anymore." Ginjo's eyebrows drew together as he pulled against the bindings cutting into his wrists tightly.

Not a word.

Aizen knew if he opened his mouth to respond, any control he had at the moment could snap like a rubber-band... He needed Ginjo alive... Only for the next few minutes at most. As the saying goes, 'silence is golden'; although, Aizen knew that probably wasn't used in the right context, but he could truly care less.

Aizen clamped his jaw tight as Grimmjow took his sweet time walking across the large meeting room. Patience, Aizen bit out the word inside his mind as he trained his eyes back down to the man on the floor. All the hatred for the substitute shinigami that had been building up to toxic levels for over the course of 24-hours, had Aizen's tongue in literally knots as he struggled with what he wanted to say, every loathing thought was wanting to come out all at once.

"I would like to say I have a high tolerance for bullshit," Aizen forced a breath through his nose to calm the tremors in his hands. It was at that moment he wished his daughter was further away from the throne room because the temptation to release his spiritual pressure to crush and smother the insect before him was truly hard to swallow back. His gaze sharpened as Ginjo merely rolled his eyes muttering something under his breath.

Aizen felt his body temperature skyrocket as his blood pressure tested new limits. Fuck the example, out right killing the pest would be more satisfying than tossing around words. It may have been due to his anger that he wasn't quite paying attention to his surroundings, but he didn't have the chance to rise up from his throne before there was a loud bang that caused some of the rooms occupants to jump after the thick tension filling the room.

Gin's snake like grin never left his face as Aizen's body was flung backwards like a mere rag-doll; one minute he was there and the next... He was laying a few yards behind, what was once, his throne. The poor backrest of the chair had been completely broken in half from the force and had shattered against the marble floor like porcelain glass.

Ulquiorra rested a hand across his zanpakuto, ready to follow any orders thrown his way. It seemed the rest of the Espada had the same idea as they each ready themselves for an enemy to appear through the double doors that were dented oddly, but nothing happened.

"What the fucking hell was that?! Did Soul Reapers follow through the garganta?" Nnoitra tightened his grip on Santa Teresa with a scowl.

Harribel frowned as she turned towards the lanky espada. "The garganta was open just enough to allow us to walk in, its impossible."

Besides, she couldn't feel any unidentifiable spiritual pressure within Hueco Mundo and she was certain Aizen would have alerted them to any unknown presence. The man was scarily powerful, and what made it worse, he knew it too.

"Mah, Mah." Gin chuckled as he placed his hands within his pockets. "You've caused a lot of trouble, Sunshine."

The grin across his face was genuine for once, unlike his typical everyday smile he forced on his face for a believable act. The small amount of dust caused by the broken throne made his view a bit unclear from his position, but he could make out the scene just fine.

Aizen scowled as he opened his dark orbs. The anger ripping away at his insides slid to the back of his mind once he took in the golden locks falling into his view. "Joji..."

"Sorry, Old man! I tried to slow down, but the floor was too freaking slippery!" Aizen winced at the volume of her voice that always rose when she got excited or frustrated. He grinned as he watched her hands move animatedly as she ranted on how the floors didn't have to be polished until they became death traps; honestly, she was just a clumsy kid, that's all there was to it. His eyes scanned every inch of her body just to bring a little comfort to his mind. Her wounds had healed to faded white scars, except for the larger one that lied on her abdomen; it had faded into a pink jagged scar that was as long as his palm.

But that wasn't his only concern at the moment.

"Where the hell is your shirt?" He narrowed his eyes at the thin black sports bra he had seen her in when Kurosaki's friend had healed her. It barely covered her... Assets.

The look of confusion that passed over her face had him scowling, because he suddenly understood why she wasn't proper...

"Eh?!" She glanced down at herself. "O-oh. I don't know." She gave a weak shrug that caused her long golden hair to fall over her shoulders, hiding her chest from view a little more. Aizen scowled as he shoved himself upright, his Joji falling from his chest down into his lap with wide eyes as he removed his long white coat. She went to protest against him but the jacket was already wrapped snugly around her frame, effectively hiding everything. While her father's jacket was filled out in the chest area, everywhere else was baggy and the sleeves covered her hands like mittens; kinda reminded her of the thick sweater her father got her last Christmas.

Ora-

You so much as whisper that dam word, Grimmjow snapped as he settled himself into his seat beside Yammy with a deep scowl. He wasn't certain why, but he felt... antsy, was that even the right word? He wasn't sure. It caused his annoyance level to rise as the very air around him seemed to irritate his skin. The urge to claw at his arms as the feeling intensified was overwhelming, so he tried to bury his hands into his pockets. He didn't know what the hell was up, but if it had anything to do with his zanpakuto, he was going to fuck some shit up; this was fucking ridiculous. No one, not one single fucking espada, went through any of the bullshit! No fucking annoying spirit, no mocking words, and no sleepless nights trying to figure out what the hell was wrong with himself.

He shifted in his seat in a failed attempt to get comfortable but the feeling stayed there eating away at his insides. He scrunched his nose in annoyance as he rolled his shoulders back. It was like a itch he couldn't scratch no matter how hard he tried.

Find.

Grimmjow brought his attention to the man kneeling in front of Aizen's throne with his hands bound behind his back. It must have been that Ginjy dude that everyone was sent to look for, he didn't look like much. What did Aizen even want with this dude? He wasn't from Soul Society, Grimmjow could bet anything on that. No zanpakuto or particularly high reiatsu that seemed promising enough for a good fight. Aizen seemed to be boiling in his seat but his spiritual pressure was still quite low considering how he normally had it. Then again, he seemed to be at a new level of pissed that was steadily climbing higher the more the Ginjy dude opened his mouth. Why wasn't his spiritual pressure getting any denser?

"I would like to say I have a high tolerance for bullshit..." The way Aizen started off had Grimmjow grinning simply because of the look spreading across his face. It was safe to say that the blue-haired man had never seen any expression remotely similar on the ex-captains face, but he was finding a certain joy in the fact that the dude on the floor was royally fucked. He couldn't see the guys face from where he was sitting, but he must have given some type of response that was the equivalent of spitting in Aizen's face.

He was attempting to ignore the feeling that was affecting his very bones as he gave his undivided attention to Aizen; he was so ready for a fight! He hadn't fought anything in weeks!

It was like Kami had heard his thoughts when a deafening bang caused him to recoil back in his seat as his ears ringed; dam sensitive hearing. Typically, he would have been on his feet by now to survey the possible new threat that could give him a great form of entertainment; however, his eardrums usually never fell victim to attack... that and that annoying feeling felt like it was ripping out his insides.

Protect orange!

"What the fucking hell was that? Did Soul Reapers follow through the garganta?"

Grimmjow placed his hand on the hilt of his sword as he scanned the room. The first thing he saw was the throne room doors thrown open with a suspicious dent forcing the metal at an awkward angle. Something, or someone, had forced their way through but there was no reiatsu signature that didn't belong in the room. Maybe it was a projectile weapon of some type. He shook his head as his spirit paced back and forth within his mindscape, growling and snarling something he couldn't make out. He was so busy trying to figure out why his spirit was being such an ass that he didn't bother to listen into the conversation around him.

Orange! Now! Now!

Grimmjow growled low in his throat as the damn animal went on to repeat those two words like a mantra. Why the hell did he have to have such a fucking demanding spirit? Don't tell him that the cat was actually wanting that stuffed fox toy at a moment like this? Is he a fucking two year old?

Apparently, his spirit didn't like being insulted because a low snarl bubbled inside his chest that Grimmjow knew didn't come from himself.

Now! Orange here!

Should he feel proud that his Zanpakuto was slowly adding to his vocabulary?

Grimmjow shook his head as his attention was pulled towards Gin. The man was already creepy enough on his own, but something about the way he was smiling at this very moment made the hair on the back of the sexta espada's neck stand on end.

"Mah, mah." The amusement in his voice was so evident that Grimmjow was certain even Wonderweiss could detect it. "You've caused a lot of trouble, Sunshine."

Grimmjow followed the silver haired man's squinted gaze that was pinned behind the throne... where Aizen was suppose to be.
The throne had been effectively smashed through and Aizen was no longer sitting amongst the destroyed throne. What the hell?

"Joji..." He felt his ears twitch as they caught Aizen's voice coming from behind the throne. Joji? That couldn't possibly be what he had heard considering the fact that he really couldn't see Aizen calling anyone 'Baby girl'.

He narrowed his eyes to see through the dust that had just barely begun to settle. He blinked as he took in the sight before him.

Aizen was laying sprawled out across the marble floor with a figure straddling his abdomen. The first thing that drawled the sexta espada's icy blue eyes was the long waist length light blonde hair that fell in wild waves. It looked so soft... Grimmjow clenched his fingers when they twitched involuntarily.

He didn't get the chance to notice anything else as his spirit was calling it out for him.

Orange! Here!

Yes, there was undoubtedly orange. It wasn't anything like the burnt orange colored fox toy back in his room, but it was a bright neon color that made him squint in irritation. Who the hell wears such brightly colored pants?

"Sorry, Old man! I tried to slow down, but the floor was too freaking slippery!"

Instead of the small squeak of a female voice he was expecting with such a petite body, a more rougher- rapsy? - voice reached his ears, that caused the hair on the back of his neck to stand on end.

Mine.

He watched as her hands flew around her body in certain gestures that went along in her rant of how the floors was 'death traps made by assholes'. All the while, Aizen hadn't bothered to move from his position on the floor as he watched her as well.

As the girl leaned forward slightly, some of her hair shifted to rest over her shoulder revealing her back. The action wouldn't have normally caught Grimmjow's eyes, but this lady was considerably underdressed. Usually, a naked woman wouldn't phase him in the slightest, but for some reason just seeing this girl's bare back had him quickly averting his gaze to stare quite hard at the individual strands of her hair.

"Where the hell is your shirt?!"

Apparently, he hadn't been the only to take notice of her state of dress, or lack of therefore. He couldn't see her face from where he was standing and it made him want to walk over there to look, but he stayed glued to his spot.

The woman's head quickly jerked to looked down at herself. "Eh?!" The rest of her hair that covered her back followed the movement so it rested over her shoulders. From the distance he was standing from the mysterious blonde and Aizen, he couldn't train his eyes on any specific thing for long before something else on the girl caught his eye: a scar. The scar was impressive in its own right as it oddly took on the shape of Lightning bolt, a dark pink against her tanned skin. There was no way the cause of that injury had missed her liver and it didn't look like the wound had been that long ago. The only scar he could visibly see, that rivaled the lightening shape one, was a scar that was easily as big as his fist going through her left shoulder. It was several shades lighter than her skin, with jagged edges. It looked like the wound had struggled to heal itself.

Hurt! Protect orange!

Grimmjow rolled his eyes. It was obvious the girl had been hurt... wasn't like everybody else in the room didn't have their fair share of scars. And he absolutely refused to get the plushie from his room just to appease the panther.

Said spirit let out a snarl in reply and Grimmjow could picture the overgrown cat swiping his claws with his ears pinned back clearly in his mind.

Orange! Here! Here! Mine!

Grimmjow gritted his teeth in annoyance at the stupid panther as he eased himself back down in his seat as he saw the rest of the Espada slowly start to do the same. Aizen had finally took the moment to rise up from the floor and shrugged off his white coat. The brunette man wrapped it around her body tightly, successfully hiding her as it hung loosely off her shoulders and arms.

"What are you doing out of bed?" Aizen stood up, holding his hand out to the girl with a frown. Grimmjow knew that frown as it was typically used when he was displeased with an enemy before they ended up dead.

"You act like I'm weak, Old man. I'm fine." She didn't take his hand as she stumbled to her feet. Being significantly shorter than Aizen, she only reached just below the man's collarbone. Instead of the coat coming to her ankles like it was suppose to, it pooled across the floor at her feet.

"Just a few hours ago, you were bleeding to death. You should not be up for the next few days at least."

If she was bleeding out just hours before, how was she standing there now? It had to have been that orange haired girl, -Hime something.

The blonde took a step forward until she was nearly pressed against Aizen's chest before she slapped her hands on either side of his cheeks. "Read my lips, Old man. I am fine, do you understand?" She spoke slowly as if she was speaking to a child before she lightly patted his cheeks.

Aizen blinked, a little dazed as she moved away from him. Grimmjow scrunched his eyebrows in confusion as he watched the girl perch herself across the reminders of Aizen's throne.

Aizen sighed as he ran his fingers through his hair. "Very well, but only for a few minutes, darling."

She snapped her head around to scrunch her nose at the man with a frown. "Aw, come on! Don't call me that, old man!"

Grimmjow swallowed thickly as he saw her face. Her facial features seemed to match her perfectly with a small little nose, natural pink lips, three thin lines marked both her cheeks that made her seem more exotic, and... he liked her eyes most of all. Unlike his own eyes, she had a deep sapphire color that seemed to reflect the lights, he had never seen any color similar to it.

Mine.

Why did he keep repeating that word?

"You!" The word was practically growled out by the Ginjy dude who was almost forgotten on the floor.

The rooms attention shifted back towards him with ease as Grimmjow kept his gaze locked on the blonde. Something felt... familiar about her, but he knew for a fact that he had never met her in his life; he would have remembered those sapphire crystal blue eyes if he had.

The blonde lady's mouth dropped slightly as her gaze landed on the reaper, eyes narrowing. Her facial expression was actually quite comical to see. "Oi, what are you doing here?!" The hard edge her eyes gained made Grimmjow freeze in anticipation. He knew that look.

"I brought him here, Joji." Aizen stepped over the pieces of white marble that had once made up his throne as he made his way over to his... daughter. That word felt wrong on his tongue when he thought of Aizen. Maybe they just seen each other's relationship as one of a father and daughter; it would explain why they look nothing alike. Aizen must be manipulating her to his whim then, she had something he must want.

Her nose scrunched up again causing the whisker looking marks to rise with the action, She looked like a annoyed little kitten. Grimmjow sat back down in his chair, his wrist hanging gently off the hilt of Pantera.

"Wha-why would you do something like that?!" One thing was for sure, she wasn't quiet when she opened her mouth.

"You were brought in nearly dead, Naruko. Gin reported that you were fighting against this reaper. And he isn't about to get off with a slap on the wrist." Aizen stood by her at the throne as he glared down at the reaper with a scowl.

Naruko. That's her name. Grimmjow repeated it once more in his head; he didn't know what it meant but it sounded like it fit her perfectly, even if the name was a little... Uncommon, he guessed that's one way to put it.

"I don't need you to fight my battles! I'll deal with the guy!"

Grimmjow raised a eyebrow. It wasn't typical for the girl to 'deal' with a fight when it came between her father and another dude. Wasn't the girl suppose to... cower or something?

Aizen's face twisted in a way that it seemed like he had eaten lemon. Grimmjow grinned at the look. "No, h-..."

Whatever Aizen was going to say was completely cut off as Naruko was already removing the bindings. Ginjo stood up as he rubbed the red skin around his wrists as he glared down at the blonde.

"Naruko!" Aizen's spiritual pressure spiked dramatically as did his tone as he scolded her. Ulquiorra took a small unnoticeably step forward as he placed his hand on the hilt of his sword, waiting for any type of signal from his leader. Gin chuckled as he stuffed his hands inside his pockets.

"What did I-..." Grimmjow would have laughed at the fact that Aizen, once again, didn't get to finish his sentence, but his mind backtracked once he saw Ginjo's body slam into the wall across the room, creating a sizeable crater. What the hell? His eyes locked on to Narukos tense form, her hand outstretched in a fist. Did she just punch the guy?

Nnoitra cackled, his grin stretching across his face in a creepy manor, "Holy shit, that was sexy as hell! Who knew Leader-sama would be keeping this to himself all this time?" He made show of licking his lips as he eyed the female.

Mine!

Grimmjow rolled his eyes. The espada only proved his level of stupidity within three seconds. How the hell did he not catch on that the blonde was Aizen's daughter? Grimmjow knew he didn't have the highest IQ when it came to most things outside of the battlefield, but he could at least catch on to things of common sense; Nnoitra didn't seem to have any level of intelligence if it didn't involve his crotch, even then it was highly limited.

Ginjo was quick to recover as he used the wall to launch himself towards the blonde, a broad sword in hand causing Grimmjow to blink. Where the hell did that thing come from?

Protect! Now!

The overhead swing held a lot of strength behind it, there was no way the petite woman could block. And the amount of distance between her and the blade was too short to dodge. Grimmjow subconsciously leaned forward slightly in anticipation as he watched the blade come closer to its intended target. The way her muscles tensed, he thought she would try to dodge, most likely to the left, considering how her hips were turned in that direction; but he was proven wrong. Instead of dodging, she used the back of her hand to slap the flat of the blade off to the side leaving Ginjo's stance open for attack; she used it to the fullest. Using her legs, she swiped his out from beneath his body before delivering solid punch that only made his face meet the floor quicker.

Grimmjow winced as his hearing picked up the crunch of bone, idly wondering if that was the guy's face or the woman's poor knuckles. He had never seen a woman do combat with only her hands and legs used as a weapon, usually females relied on a weapon like a zanpakuto.

"There." Naruko scratched her cheek before placing her hands behind her head, "Emo can take the dude back to the world of living, I got my revenge."

Aizen sighed, "That isn't how it works, Joji." Nonetheless, he waved 'Emo' forward to pick up the unconscious reaper. Grimmjow chuckled as he saw that 'emo' was Ulquiorra.

"Now, that's solved. Mind telling me what started the fight in the world of living in the first place?" Aizen wasn't asking.

Naruko gave a nervous laugh at the question as she dropped her arms down by her side. She lean back on her heels for a moment, "...He's just a ero-baka. He felt my reiatsu flare when I got angry at him harassing a woman at the park, must have thought it was interesting."

Reiatsu flaring up could be taken as a taunt of battle, sometimes being mistaking in the reason behind the outburst. Grimmjow flared his reiatsu up as a show of dominance over his opponent, it was a great way to display one's power without much effort.

Aizen's facial expression couldn't grow much darker than what it was. "You're not to leave Hueco Mundo for the next few months. I can't risk my enemies taking advantage of you to get to me."

Grimmjow saw the reason why the ex-captain wanted the little blonde to stay behind. It would effect every detail that had been planned and one failure could mean Hueco Mundo falling along with several vasto lords bodies. That wasn't a great option.

"What?! Are you serious right now?! You are going fuckin' senile! The Shinigami doesn't even know I EXIST, let alone my relation! You've locked me up like some fuckin' damsel in distress for two centuries! I am not a pet to cage!"

Grimmjow raised an eyebrow. He could also see her point, but his mind was too busy processing the tense muscles coiled beneath her tanned skin, the slight fluster of her face and how her cheeks puffed out. Her eyes grew a few shades darker, looking as if she wanted to kill something any moment. It seemed her anger had sparked something with her reiatsu as it flared out around her body in a dense orange glow. Ulquiorra, who had already made his way over by this time, was picking up Ginjo from the floor when Naruko's reiatsu burst outward, knocking him back across the room with the unconscious soul reaper following. It was quite funny how the stoic espadas eyes widened to a comical size so grimmjow couldn't stop from chuckling; the bastard deserved it. Even though her reiatsu didn't feel like a hollows, it held the density... Maybe even rivaling it. He had to blink when he took notice of the pair of black tipped vixen ears. Where the hell did those come from?

Mine.

Why did he keep repeating that?!

"I do what I see fit for your best interest. Now go to your room, Naruko." Aizen seemed just as fed up with the conversation as the blonde was. He waved his hand dismissively towards the door.

"You do what benefits yourself, everyone knows that." Unlike her previous way of speaking, her voice was calm and held a underlying tone that had everyone on edge.

Gin couldn't hold back his snickering as he covered his eyes with the palm of his hand. He loved listening to her fire off at Aizen; mostly because she was the only one that didn't fear the ex-captain, so there was never any hesitation to completely roast him in their arguments. She always had quick rebuttals, it didn't matter the topic. Aizen never seem to be able to figure out how to react or respond so it was always predictable...

"Room, Naruko."

Her reiatsu didn't lose its flare as she turned on her heel, her eyes reminding Grimmjow of ominous storm clouds. His mind was so busy inscribing every tiny detail of the blonde as she walked past the table, that he didn't notice how Nnoitra was doing the same.

"What a bunch of dogs..." Halibel mumbled as she saw nearly half the Arrancar sitting at the table openingly ogling the young woman who obviously had strong close knitted ties to Aizen and Gin. Was that drool she saw?

Aizen's reiatsu snapped sharply making Gin silence himself with great difficulty.

Aizen's anger must have blinded him in Halibel's personal opinion, because his next words wouldn't have been even whispered if he had been more aware of his espadas behavior.

"Grimmjow, you are to guard my daughter at all times. She is not to leave her room until I inform you."

Yes, Aizen had not been paying attention at all.
