A/N: Big thanks to all who have already shown their support with this story ^^ since the first chapter was received so well :) I'm posted this one ahead of schedule. A couple of quick notes before chapter 2.

While being an AU story, I use a mix of the books and movies as part of the pre-story background as you'll see in the first part of this chapter; it's a mix of the final part of The Battle of Hogwarts from the book and the film as well as some AU. As I stated at the end of the last chapter, this chapter runs parallel with the previous chapter but is centred on Bellatrix, starting slightly ahead of Ch1 in the timeline and ends at the same point Chapter 1 did. Last point, in the rush to post Ch1 I may have forgotten to post the warnings, so they are posted here as well as Ch1 :)

Warnings: This fic contains sexual content, some of it non-consensual, there will be abuse and violence, and mentions of delicate subjects although I will warn you about them in the relevant chapters.

Disclaimer: The world of Harry Potter and the original storyline are not mine; they belong to J.K. Rowling.

Read, review and most of all… Enjoy!

Chapter 2: Treacherous Blood

Bellatrix

(Present Day)

Her eyelids felt heavy and it took all of Bellatrix's strength to force them open. The light was blinding and everything was a blur, she couldn't make out anything, her surroundings were too distorted. A lingering yet sharp agonising pain shot through her heart and worked its way down her body, Bella's lids clamped closed as she winced. Confused and in pain, she gritted her teeth and tried to think back to the last thing she could remember in the hope of answers but in the process fell back asleep.

(1 Week Ago)

Victory had all but been secured. Itty-bitty-baby-Potter was dead and the pitiful Order and their supporters had been crushed, their spirit and morale broken. Or so Bellatrix thought as she stood up high on top of a pile of rubble, heckling and laughing at her Master's enemies distraught faces, as the Dark Lord broke the news of the chosen one's death with pleasure to those that still stood.

Her Master then went on to offer all those present a chance to pledge their allegiances to him, she dug her nails into the palm of her hands hard to stop herself protesting. It wasn't her place to question her Master's wisdom, especially in public. 'I must believe the Dark Lord knows what he's doing… But… There are a lot of undesirables here… Mudblood vermin and blood traitors!' Her eyes scanned the crowd, picking out those she knew fitted firmly in those categories, the Weasels, ickle baby Fatbottom, the woman who was almost identical to her in looks… Her disgraceful blood traitor of a disowned sister, Andromeda.

'How dare she show her face here!' Bellatrix let out a low hiss as their eyes met then grinned at her sibling's hurt expression. 'I wonder if her whelp… The abomination, survived our little duel.' The memory of crushing her niece in a fierce duel while her mother looked on in horror, caught in a duel of her own, almost brought tears of joy to Bella's eyes. She would never admit it of course but her niece had put up a good fight and was admittedly the best opponent she had faced during the battle, she was even slightly… And only slightly, disappointed when her niece fell, but only because she had been enjoying the fight so much. 'She definitely didn't get her skills from the mudblood filth in her blood.'

Bellatrix wondered if her sister was surprised at her for not killing her niece. But she'd be an even bigger fool to believe Bellatrix did it out of any sort of love or family loyalty, no, her reasons were simple and more sadistic. She found killing her opponents too anticlimactic, if they died by 'accident' or because they were too weak then so be it. But Bellatrix preferred to cause agonising and long lasting pain, she preferred to leave them drowning in their own blood, clinging onto life with a splutter as she walked away swaying her hips seductively. And if… If they went on to survive, then her brutal actions often would leave a permanent scar in their minds and on their hearts for the rest of their now ruined lives. How could granting the sweet release of death ever compare to that? Every one of her victims were living trophies, each one a testimony to her skill.

She watched as her nephew, Draco, was the first to break away from the group and approach the Dark Lord. 'Why were you even over there in the first place my dear little nephew?' She thought as her eyes followed him suspiciously. 'Talking about trophies!' Bellatrix cackled as Neville Longbottom approached the Dark Lord next. His parents were her masterpiece, her most treasured work. But only she, Narcissa and the Dark Lord knew the true extent of her motives for why she did what she did to the Longbottoms, motives which were different from those she proudly proclaimed all those years ago. 'I swore vengeance on them; I promised myself I would not rest till I took my revenge… And I did!'

The idiot boy started to ramble on about 'Fallen allies still being with them.' Bellatrix rolled her eyes and hoped the Dark Lord would silence him, but he seemed to be humouring the boy. She forced back a sigh and let her mind wonder and kept surveying the crowd, still pondering what use the Dark Lord would find for the undesirables. 'Hmm, perhaps he wants to use them as slave labour in the remodelling of wizarding Britain? And maybe as servants and playthings for his most faithful and loyal subjects… Mmm yes…' That idea peaked her interest and she made a mental note to put it forth to her Master, just in case it wasn't on the cards.

Bellatrix felt she had earned a little leisure time and as much as she absolutely loved the thrill of combat, she missed having a helpless plaything in her possession, begging and pleading for mercy. Her taste for such activities had been rekindled at her darling sister's mansion just over a month ago and she knew just who she wanted back under her blade.

Bella's eyes settled on the one called Granger who had served as the catalyst for her renewed cravings, one of the weasels had his arm around her and it took all of Bellatrix's restraint not to hex the boy there and then. 'No one touches my possessions! No one!' As far as Bella was concerned, she had laid claim to the girl and the muddy belonged to her, she had been marked by her and one thing Bellatrix most defiantly didn't do, was share. But Bella's claim on the mudblood was based on more than a simple 'I had her first.' Apart from being everything Bellatrix despised, she was also the spitting image of someone from her past, her height, her skin tone, her hair, her eyes, her features, her… Everything! She was practically identical in every way and Bellatrix took that as a grave personal insult.

Then… Things changed very quickly. The glint of silver and rubies in the corner of her eye, snapped Bellatrix attention back to the Longbottom boy who had just drawn that blasted sword from the sorting hat. Gasps and low cheers started to break out, she initially thought it was because of the silly little magic act the idiot had performed. Then a familiar voice shouted out a spell behind her. 'No it can't be!' Bella spun round and her eyes widened in surprise as Potter ran past her, very much alive. She had to duck quickly to avoid being hit by a spell from her master aimed at the boy and quickly retreated out of the line of fire. Her eyes followed Potter, still dumbstruck at the most unwelcome surprise, the sounds of people panicking and disapparating forced her attention from the boy and to her comrades.

Bellatrix couldn't believe her eyes, a large number of them were… Fleeing! "COWARDS! COME BACK! COME BACK HERE AND FIGHT!" Bellatrix shirked at the top of her voice, but she swayed no one. "TRAITORS! FILTHY COWARDS THE LOT OF YOU!"

She wished she could have caught a few and made examples out of them, but for now she had a fight to win for her Master and began to push forward by his side. The Order fought back harder than before, spurred on by false hope, no longer did some of the lesser witches and wizards turn and flee when they saw her approach and instead ganged up on her in pairs and groups of three. She fell them as quickly as they came and breached the Great Hall with her Master and those that remained loyal, hoping to find Potter here, where the Order had decided to make its final stand.

The fighting should have been exhilarating, but instead Bellatrix felt strangely empty and very confused. 'Something isn't right! He was dead! Cissy said so herself!' During the commotion she lost sight of her Master when he went to kill the Longbottom boy for managing to behead Nagini. Because of the cowards that fled, the remainder of her Master's forces were heavily outnumbered and many had started to fall to overwhelming numbers. Even Bellatrix was feeling the strain, or to be more accurate the wand she was using was. Her original wand had been taken during the skirmish at her sister's manor, so she had been forced to use one of the spares Greyback had stolen from Ollivanders when they kidnapped him.

Pure will alone had been enough to keep the unfaithful wand in check and obey her every command up into now, but the ferocity of her own attacks and the ones used against her was causing the wand to buckle under the pressure. Bellatrix caught sight of her master duelling the Auror Kingsley and her former Professors, Slughorn and McGonagall. She had planned to go fight by his side, but the sight of a familiar 12 ¾ curved walnut wand in the hands of that filthy mudblood drew her attention. Bellatrix quickly made her way over to them, cutting a clean path through anyone that tried to stand before her and soon found herself face to face with the mudblood Granger, the female weasel and the loony blonde girl.

"OI! I believe you have something of mine muddy!" Bellatrix shirked and directed a powerful curse in her direction, the young witch blocked it and didn't reply to her but the fear in her eyes was clear, as was the shaking of her hand as she held Bella's wand tightly. "How dare you! How dare you steal from your betters! Your filthy mudblood fingers have no right holding a wand!"

She shot numerous curses at the trio while they took it in turns to defend each other and return fire, Bellatrix had little issue defending and attacking at the same time, although her wand did waver a few times. The other two girls were a mere pest and Bella wanted to focus her full attention on the brunette so despite liking to toy with her opponents, she tried to despatch the ginger one hastily. "Avada Kedavra!" She shrilled out loud; it should have struck true… But at the last split second her wand buckled again under the pressure and the curse shot slightly wide.

Her attack didn't go unnoticed and the matriarch Weasley pushed past the three younger witches. "Not my daughter, you bitch!" Mrs Weasley spat out.

Bellatrix laughed in the face of her former school rival and taunted her over the death of one of her sons as they exchanged curses. She could have easily overpowered the blood traitor but Bella couldn't resist trying to show her up one last time, just like she used to in her years at Hogwarts as she danced and laughed between spells. But then… The unthinkable happened, Mrs Weasley sent a powerful curse, one that Bellatrix could have easily blocked and attempted to, but her replacement wand had had enough and misfired. Her shield failed to manifest and the curse struck her chest, directly above her heart.

The world froze around her and her eyes bulged, unbearable pain ripped through her heart and her lungs seemed to burn as if engulfed by a fire burning under her skin. Her strength fled her body and Bella's legs gave way causing her to topple. The last thing she heard as she hit the floor was the triumphant cheers of the Order and the fury of her Master, her eyes fixed on the enchanted sky of the Great Hall as her orbs dimmed and her life began to fade.

(Present Day)

The murmur of voices woke Bellatrix back up, as before she struggled to open her eyes and this time she chose to keep them closed. Instead she focused on the approaching voices and the opening of a door, half of it sounded like a buzzing noise and she found it difficult to tell who the voices belonged to.

"Why are you here? She won't want you here! I don't want you here! Nothing's changed, I've not forgiven you and she most defiantly hasn't!" One of the voices said, it belonged to a female that much Bellatrix could tell but other than that she could only guess. 'Cissy?'

"Despite what you two think, she's still my sister. I can't turn my back on her when she's in this state." The second voice was also female; it came through her ears distorted by the buzzing… But the way she referred to her… 'I'm sure she said… Still my sister… If the other voice is Cissy then this has to be… Andromeda!' Bellatrix wanted to scream and shout but her throat constricted, instead she made a gurgle that was barely audible. "And everything has changed. Your involvement in the end… If… No, when… She finds out… Do you honestly think she'll still call you sister after? I can tell you now, she won't and you know it. She'll think of you the same way she thinks of me!" 'What's that meant to mean! Cissy could never be a blood traitor like you Andy!'

Bellatrix waited for Cissy's retort, but one never came… Instead a silence filled the room, and that lack of response scared Bella. "What did the healers say?" Narcissa finally spoke again.

"She's recovering fast and can wake at any moment. But her heart will be fragile for a while; they are still amazed she survived." Andromeda replied and footsteps rang in her ears as the sisters got closer.

"I'm guessing the Ministry already knows she's better? I saw a lot of Aurors hanging around." Bellatrix's hearing must have started to clear up slightly and she heard the concern in her little sister's voice. 'What the hell are they talking about?'

"Yes they were arguing with the Healers earlier. Now that she's stable they want her shipped to Azkaban right away, but the Healers are insisting she still needs a few weeks to recover fully." The mention of the wizarding prison sent a cold chill down Bellatrix's spine and her sister's words did nothing to unravel her confusion. The only rational reason that crossed her mind was that the Dark Lord was punishing her for something, 'Maybe he's ashamed at me for losing to that red headed bitch… But that wasn't my fault!' And that didn't even begin to explain why her treacherous sister was here and walking around so freely. 'Where ever here is…'

"She's in no condition to be moved! Are they trying to kill her?" Bellatrix gave up trying to work out what was going on, her head was throbbing painfully so she just laid and listened.

"I wouldn't be surprised if they were, if they had their way last week, they would have killed her there and then. You saw what they were like after Voldemort was defeated." 'The Dark Lord defeated?! NO!'

Bellatrix's heart skipped a beat, which sent a jolt of pain through her as that lie filled her ears and finally, she found her voice as she screamed out in denial, her eyes snapping open. "NO! YOU LIE!"

"She's awake! Bella?" Cissy squealed out and sounded relieved, her footsteps came closer.

"Cissy?"

"It's ok Bella… I'm here." Narcissa's head appeared in the corner of her vision and Bellatrix tried to sit up, only to find she was being held down by some unseen magical restraints. She let out a low growl and instead turned her head to her baby sister and gave her a slight smile, before her eyes wandered over to the blood traitor, still standing close to the doors.

"Get. Out!" She hissed dangerously low.

"I'm not going anywhere Bella." Andromeda said calmly, she neither moved closer nor further away from her older sister.

"Don't! Call me that! You lost that right long ago! Now… Get out! GET OUT, GET OUT, GET OUT!" She screeched as loud as she could till her throat threatened to tear open, her voice quickly was reduced to a blend of coughing and spluttering. A soft hand belonging to her little sister, snaked its way into one of hers and squeezed it gently.

"Andy… Please… You said yourself, her heart's fragile… She can't get worked up like this." Narcissa turned to look at her other sibling, her expression was, for whatever reason, surprising passive.

Bellatrix stared at Andromeda with a dark glare; her breathing was laboured as she tried to gather her voice for another volley of screaming. "Ok, I'll be outside." Andromeda said with a sigh and nodded to Narcissa, which she replied to with one of her own. Her disowned sibling gave her one more inquisitive glance then left through the double doors.

The second Andromeda left the room Bellatrix started firing questions at the little sister until her voice went hoarse. "Cissy! What's going on? Where am I? What happened to the Dark Lord? Why am I tied down to this bed and why… Why was she here?"

"Bella please, calm down. You need to take it easy." Narcissa spoke quietly and her other hand came up and covered Bella's. "You were badly injured in the battle at Hogwarts… You took a strong curse to the chest, to the heart… I thought I lost you Bella!" Bellatrix softened slightly as Cissy started to sob, wishing she could sit up and awkwardly comfort and reassure her sister. Usually Bellatrix couldn't tolerate crying, unless of course she was the one to cause the tears… Except when it was Cissy who was shedding them, she always had a way of finding that soft part in Bellatrix's heart.

Being tied down made it difficult for Bellatrix to show one of her rare bouts of affection, so instead she gave her sister a small smile with soft eyes, her fingers gently caressed Cissy's hand."Shh now Cissy, it will take more than that feeble excuse for a witch to put me down for good… Now, what's happened? Where is the Dark Lord?"

"Bella… Please. It doesn't matter right now; you need to take it easy."

"Cissy! Just tell me!"

Narcissa studied her face then sighed before starting to fill her in one what happened after she fell in battle. How Potter defeated and killed the Dark Lord, which Bellatrix immediately voiced her rage and was adamant it was a lie. It wasn't till Narcissa showed Bellatrix her faded Dark Mark which had been covered up, and a memory of Voldemort falling, which she witnessed herself, did Bellatrix accept it. But her acceptance didn't mean her silence; as she shirked with rage and grief at the top of her lungs until once again she was reduced to a serious coughing fit. The doors opened and a woman in a lime green robe stepped in, the healer began to move over to Bellatrix's side but the dark witch warned her away with her eyes and instead she hanged around to observe her patient.

When Bellatrix eventually calmed down, albeit only slightly, she demanded for Narcissa to keep going. Her sister told her of the incident in the Great Hall, where some wanted her to be left to die, but the mudblood Granger, herself and Andromeda stood in the way. Bellatrix couldn't help but be shocked at that unlikely trio coming to her aid; she understood why Narcissa did so and maybe why her fool of a blood traitor sister did… But her mind couldn't work out why the hell the mudblood had. Cissy then went on to break the news that Bella was being held prisoner in St. Mungo's, in a private secure room until she was fit enough to be sent straight back to Azkaban without trial. As for Andromeda's presence, Cissy seemed to avoid the subject and said she didn't really know.

Bellatrix didn't speak for a while; her eyes left her sisters gaze and stared up at the ceiling. It was a rare thing for her to be at a loss for words but her tongue was as tied as her mind was muddled 'This can't be happening! It was going so well… We had practically won!' She needed to find something to focus on, something simple while her mind untangled the distressing barrage of information. So she began to take in her surroundings and the first thing her eyes focused on was, a disturbingly dull and plain white ceiling with a dark iron ring hanging from it with four copper lamps attached. Her eyes moved to where the ceiling ended, a single row of small black glazed tiles formed the top of her room's walls, her eyes followed one of the walls down, the top half was the same dull white colour as the ceiling with lamps spaced out at equal lengths. 'No windows… Even in Azkaban I had a window…'

The bottom half was made up of the same glazed black tiles, patterns had been curved into the surface, images drawn in white depicting the hallmark of St. Mungo's. Apart from her bed, the only other thing to take up the space in her room was a small dark wooden desk which the healer was sitting at, scribbling away with a quill. Her eyes moved along to the dull metal reinforced double doors with small windows embedded in them, they served as the only entrance to her medical prison. The sight of wild light brown hair through the window prompted a question to her mind.

"What did she mean?" She finally asked with a hiss.

"She? You mean…?" Cissy followed her sister's eyes and saw the faint image of Andromeda out the windows in the door. "What do you mean?"

"Your involvement in the end… She seemed to think you did something that I wouldn't be very happy with… Something that would stop me calling you my sister… What did she mean?" Bellatrix's eyes narrowed on Cissy, studying her expression.

"I don't know what she meant…" She replied quietly but despite how hard she must have been trying to keep her face neutral, the colour in her cheeks betrayed her as it faded and gave her a deathly pale and horrified look.

"Don't lie to me Cissy! You didn't deny it! You know what she meant!" The dark witch snapped, even if she had the strength to utilise Legilimency, she wouldn't have needed it, it was clear to her that Cissy was hiding something.

"I…"

"What. Did. You. Do?" Bellatrix could feel what little patience she had beginning to wear thin.

"I lied…" Narcissa quickly dropped her gaze and stared at her hands, still holding onto her eldest sister. "During the battle I…"

"You lied…?" Bellatrix repeated but Narcissa didn't answer. Her mind quickly began racing through the events that Cissy had been a part of in the final battle; the image of Narcissa kneeling over Potter's body became clear in her mind. Her eyes widened as she made the connection and it suddenly dawned on her what had happened. "When the Dark Lord asked you if the boy was dead… You lied… Why!?" She gritted her teeth and pulled her hand away from Cissy's sharply, clenching them both into fists.

"I had to… I had to do what was best for Draco! For our family!" Tears started to fall from the blonde's blue eyes. 'Your tears won't work this time… How could you!'

"So you betrayed us… You betrayed the Dark Lord… Betrayed me!" She gave her sister a dark hurt look then turned her head away, her eyes focusing firmly on the black tiles of the wall.

"Bella… Please… I'm sorry… I had too, please Bella… Please understand." The pleading voice of her little sister made Bellatrix cringe, her nails digging deep into her palms, refusing to allow herself to show any sort of compassion or understanding.

"She was right… You are no sister of mine…" Bellatrix felt as if her heart had just been run through with a sharp blade, the words coming from her mouth hurt her more then she cared to admit.

"Bella… No…"

"Get out! GET OUT!" Bellatrix's eyes snapped shut, hoping that pressing her eyelids tightly together would hold back the tears that threatened to spill. "I don't want to ever see you again! Now go! Go and take the other blood traitor with you, you belong together!"

"Please Bella! I'm you're sister!" She didn't need to look at Cissy to know she was sobbing her heart out as she spoke.

"I have no sisters… They are both dead to me…" Bella whispered quietly in a flat tone, her now ex-sister's sobbing increased followed by the sound of hurried footsteps retreating and the swinging of the double doors as Cissy burst through them. Bellatrix was thankful Cissy left when she did, or she might have caught a glimpse of Bella's own tears falling down her cheek.

(5 Days Later)

The Auror's didn't get their wish to ship her immediately of too Azkaban, but neither did the Healers in charge of her care get the couple extra weeks. Instead they reached a compromise and settled on five extra days as well as the odd visit from a Mediwizard to check her condition over the course of a few weeks.

She had been abruptly and rudely woken up, pushed around by Healers and Aurors all morning as they prepped her for transport on the fifth day. They were careless in their rush and she managed to kick one of the male Aurors full pelt in the crotch before they had restrained her legs. She laughed manically, feeling a bit like her old self before a stunning spell hit her.

She came around later restrained to a hard wooden chair in a dank office, she was sat opposite a middle aged man with a dark desk taking up the space between them. He had medium length dirty blonde hair with a trim shaven blonde beard to match; his eyes were brown and although hard, seemed to be masking a pained glint. Deep wrinkle lines etched around them gave her the impression that this man had had little sleep recently; it was a look she knew well… Mainly because she had caused it often enough, but this man was grieving over someone. Bellatrix shrugged then let out a bored yawn upon seeing the two pairs of Aurors either side of her, all with their wands pointed at her.

"There's no point me saying, it's nice to see you awake. We both know that would be a lie, wouldn't we Mrs Lestrange." The man opposite her said.

"Mmm, like me saying, let me out of these restraints and I won't hurt you." She growled, and then smirked as one of the younger Auror's tightened his grip on his wand.

"Quite. I trust you know where you are?"

"Ohhh let me guess! I'm a VIP at a show where Mudbloods have to fight for survival with their bare hands against a pair of dragons?" Bellatrix cackled with a hopeful glint in her eyes.

"Shut your mouth!" The younger Auror said, his wand getting closer to the side of her neck.

"Ohhh that's no way to talk to your betters boy! Let me guess… You're a Mudblood?..." Bellatrix stared deep into the boy's eyes, sending her mind forward into the Aurors. 'Pathetic defences, he doesn't even know I'm here!' "Hmm no…"

"Enough, the pair of you!" The middle age man said with annoyance.

But Bellatrix ignored him and continued to probe the Auror's mind. "Ahh haha! You're girlfriend? Awww is your woman a filthy mudblood whore?" Her tone was gentle as she quietly whispered out the insult with a grin on her face.

"I said shut up!" The Auror whipped his wand and a cut burned across her cheek, but his actions just started Bellatrix off laughing.

He went to raise his wand again but the older man stopped him. "ENOUGH! Noel, wait outside please." Giving her a long hard glare, the Auror called Noel left the room, slamming the door behind her. "I see losing the war did nothing to diminish you're hateful views Mrs Lestrange, just as well you back here then… In Azkaban. I'm Head Warden Marcus Brown."

Bellatrix snorted. "Head Warden you say? Fancy title for someone with such a pitiful office." While being insulting, her remark did still ring true. The office they sat in just seemed to be an oversized cell with a desk and two chairs chucked in, in place of a bed.

"It's a temporary arrangement. However I'm sure it's a look you remember well… Take a good look; this will be the most luxury you'll ever see again. Since you're still processed from before, there's little reason to keep you here." Marcus crackled a small smile. "Welcome back to Azkaban Mrs Lestrange."

Before Bellatrix could make a witty comment, Marcus nodded his head at one of the Aurors and Bellatrix faded out of consciousness.

A/N: I hope you enjoyed Bellatrix's opening chapter in this story :) Chapter 3 will pick up from the ending of both this chapter and the last ^^ How will they both react to seeing who they have a cell near :P Stay tuned :) and i'll update soon.
