Summary: That had always been a sore spot for Alex. How could she, a vampire, a Hellspawn with the blood of so many innocents on her hands, ever be worthy enough, faraless be a sister to an angel? Kara & Alex. Supernatural/Family.

*** ~ Angel of Darkness – Part II ~ ***

Alex will always remember the day that she, her human self, died.

It started off like any other day. She got up, went to work at her comfortable lab job in the city, and then had dinner at her parents' house later that evening. After their stomachs were filled and jokes were shared around Eliza's famed chocolate pecan pie, they all went for a late night walk along the beach. So caught up in admiring the stars, none of them noticed they were being watched. Being stalked. By the time someone did realize, the shadows descended upon them like a tsunami, without warning and violent, the screams of her mother and the yells of her father shattering the quiet night air.

They fought.

In the end, it made little difference. There were just too many of them, monsters with glowing red eyes and fangs sharper than knives. Eliza and Jeremiah were quickly torn to shreds and devoured, Alex left for last. But unlike her parents, she was not torn asunder, Alex suffering a far worse fate instead. Her head viciously yanked to the side, fangs soon sunk into her neck, excruciating pain overwhelming her before everything went black. When she came to after who knows how long after that, Alex remembered nothing from before, but the damage was done. Her soul was almost irrevocably fractured, and for a long time after that, all she knew was bloodlust.

"Alex!?"

At the sound of her name, Alex snapped out of her remembrance and turned towards the shout.

"Here," she said softly.

Getting up from her perch on the small couch she occupied, Alex quietly made her way to the only double sized bed of this bachelor's style apartment, sitting down at the edge of it. It was a small residence, enough to house one person comfortably, maybe two, the apartment empty at the time she had forcefully appropriated it. Thankfully, none of the floor's residents (or anyone in National City, for that matter) had noticed them when that happened, Alex hopeful things would remain that way. At least until they had recovered from the previous night's ordeal. Otherwise, Alex was going to have a hell of a time explaining what was going on here, and she was certainly not looking forward to that.

"Hey," Alex said, enveloping her trembling sister in a hug.

Kara was reaching for her even before she opened her eyes, the blonde twisting her entire upper body towards Alex, arms outstretched when she drew near. The moment Kara's hand touched her arm, the Kryptonian immediately latched onto her like a koala, Kara burying her face in the front of Alex's shirt. With no trench coat in the way, Alex's jacket currently draped over the back of one of the dining table chairs, Alex's gun and rest of their meager arsenal spread out over the table itself, there was little to keep them apart now that Kara snared her.

"I got you," Alex soothed, paying no heed to how tightly the younger girl was clinging to her. Had she been a purebred Hellspawn, such contact would have burned her like acid. As it was, nothing happened.

"I got you."

A whimper escaped Kara's throat as she tried to further erase the minute distance between them, all the while Alex gently stroking her sister's hair.

"Kara," she murmured, leaning in to plant a kiss on the crown of Kara's head. "Hey. It's alright. You're alright."

To that Kara shook her head, the first of many sobs filling the quiet air of the apartment, making Alex frown.

"Kara-"

"I'm sorry," Kara murmured, her voice choked.

Pursing her lips, Alex tilted her head downwards trying to catch her sister's gaze to no avail.

"For what?" she asked.

"For you getting hurt," Kara hiccuped, the grip around Alex tightening noticeably.

"Kara," Alex said, frowning more. "There's nothing to apologize for. You didn't do anything wrong."

"But this was my fault," the Kryptonian said, Kara pulling back enough to press a hand against the hole in the front of Alex's shirt, directly over her heart.

In all the madness to escape last night, Alex hadn't had the time to scrounge around for a change of clothes. None of the clothes in the apartment fit her unfortunately. The apartment's owner, some Margaret Sawyer as stated by the unopened mail left on the kitchen counter, was apparently a very tiny person. And that left Alex with no other option aside from wearing her own ripped clothing for the time being. It was too dangerous to show her face outside at the moment, either of them, the NCPD and other law enforcement agencies swarming National City and the forest at the outskirts because of last night's scuffle.

"If it wasn't for me," Kara's voice broke. "You wouldn't… You wouldn't have…"

"Kara-" Alex shifted slightly, trying to meet her sister's gaze again. That proved difficult as the blonde's eyes we locked onto her chest where barely a scar remained, watery eyes unwavering at the horror hidden under the hand covering it.

"It was so horrible, Alex," Kara cried, her face twisting in torment. "It was so bad. It was so horrible."

A heaving breath.

"When he came after us," Kara rambled, her entire frame shaking. "And then his hand was in your chest-"

Alex pulled Kara back into her arms, not knowing what else she could do to take away the deep pain rolling off of the younger girl's words. Kara always did blame herself for things out of her control, bearing a burden she shouldn't have to carry, but did so anyways. Alex never understood why, but she suspected it had something to do with where the other girl had come from. This Kryptonian, this angel, was truly a pure soul in this undeserving world.

"It was like Krypton all over again," Kara sobbed, her face buried in Alex's shoulder.

Alex clenched her jaw to keep herself from doing something she would regret. Namely leaving Kara right this instant to hunt down and obliterate the ones who caused her suffering in the first place.

"So many people died," Kara wept, white knuckled fists threatening to tear a new whole in the back of Alex's shirt. "And I couldn't do anything, I couldn't stop it."

Closing her eyes, Alex nuzzled her cheek against her sister's head. It was of little comfort considering the horrors Kara experienced in the past, and continued to experience now because of what she was, but it was something nonetheless. Never one for physical affection, such times were exceptions, Alex willingly shedding her cold and detached exterior to do what she could to ease her sister's lingering anguish.

"When he was hurting you," Kara said, her voice thick with something Alex had never heard before from her. "I couldn't not do something about it again. Not again."

Kara shuddered before going absolutely still, Alex's eyes blinking open at the sudden silence.

"So I made him pay!" the angel said, almost snarling.

Alex froze for a moment at the venom in her sister's voice. Since first meeting the young blonde all those years ago, Kara had always been timid and fearful, and at times clingy. She was also caring and compassionate to a fault, but never vengeful. Not like this. Even after she had lost her entire world and everyone she loved, she had never acted like this.

"Please don't hate me…"

Sounding very much like the scared little child Alex had met over forty years ago, Alex tucked a lock of hair around Kara' s ear before pressing a kiss to her sister's temple.

"Kara," she said, rubbing soothing circles onto Kara's back. "I could never hate you. You are my sister and I love you. No matter what."

Alex could have sworn she heard the back of her shirt rip as the hold on it tightened again.

"You shouldn't," Kara murmured, her tone full of bitterness and self-loathing. Had those words been spoken any quieter, Alex wouldn't have heard it.

"Why not?" Alex asked, brows furling. She looked down at the head of blonde on her shoulder.

"Because I'm a murderer!" Kara exclaimed, her chest heaving with shuddering breaths. "I killed him and-"

"No Kara," Alex interjected before her sister could go off on a rant. Her jaw clenched immediately, something Alex would later realize was the first of many signs she was losing her cool. "You protected me. Like I will always protect you. There's a difference."

"And that's supposed to make it better?" Kara questioned, pulling back to look at Alex, a tinge of anger creeping in. "I killed a man, Alex! I-"

"No Kara," Alex interrupted again, her words tight, her eyes flashing red. "You didn't. It-"

"Alex-"

"He was an abomination!" Alex erupted, her fangs bared, a snarl escaping her throat. "He was not a man, or a human, or an animal for that matter! He was a god forsaken monster! He deserved to die! Just like the rest of us Hellspawn!"

Kara stared at her open mouthed and wide eyed as she panted, it taking a few seconds for Alex to realize what she just said. When it finally hit her, Alex's expression dropped, and she squeezed her eyes shut and turned away from her sister. Silence lingered between them for nearly a minute before it was broken again.

"Alex-"

"Don't, Kara," Alex said, her voice thick with emotion. She refused to look at the Kryptonian. "Just don't. If there's anyone worth crucifying, it's me."

"Alex-" Kara tried again.

"Once a Hellspawn, always a Hellspawn," Alex continued bitterly, her hands balled into fists at her sides. "Because of you, humans may not be my first choice of kill anymore, but the urges are still there."

A frustrated growl.

"And because of that," Alex forced out through gritted teeth. "I will kill until the day I am truly dead, simply because it is in my blood. Because I am evil, a plague upon this world that deserves to be purged."

Red coloured eyes snapped to the side to meet watery blue ones.

"So don't," Alex repeated, her voice guttural. "Don't cry to me about murdering one of the many demons plaguing this world. Because really, you've got nothing on me."

Unable to look at her sister anymore, Alex turned her face away to get up. Before she could go far however, two hands cupped her face, their touch comfortingly warm as they steered her back towards blonde hair and blue eyes.

"You're not like the others, Alex," Kara said, her eyes rimmed red but no longer tearing. "You may think so, but you're not."

Alex swallowed thickly, blinking back the sting in her eyes as she struggled between staying put and ripping herself away from her sister to storm away.

"You are the only reason I've ever felt at home on this world," Kara continued, her thumbs wiping away the tears Alex didn't even realize was falling. "When I first came here, I never thought I'd be able to find a life outside of Krypton. But I did. Because of you. Because you were, are, my sister."

Realizing it was lost cause, Alex sniffed once before she reached upwards to hold the hands holding her face, her lips trembling.

"But we're not sisters," she said. "Not by blood anyways."

That had always been a sore spot for Alex. Not the fact that they weren't physically related, but the fact that Kara, since their initial, bumpy meeting, had looked up at her as if she really was her big sister. How could she, a vampire, a Hellspawn with the blood of so many innocents on her hands, ever be worthy enough, faraless be a sister to an angel?

"You don't have to be of the same blood to be family, Alex," Kara said, giving her a small, kind smile. Pulling her forward, Kara pressed her forehead to Alex's.

"Besides," Kara rambled on. "What you said before isn't exactly true. You did bite me all those years ago – not that you really realized what you were doing at the time, but that's besides the point – so technically we do share blood. Or at least I do, in a weird sort of way. So that makes us sisters. And even if that does not, I say so. So… yeah..."

Eyebrows raised in surprise at how quickly things turned around, Alex chuckled for a few seconds before she shifted back a bit to brush away the remainder of her tears before they fell. Here she was trying to make Kara feel better and less guilty, and yet that's what the angel did for her.

"When did you get so smart?" Alex said, a smile finally stretching across her face. She couldn't explain it, but it felt like a huge weight had been lifted off of her shoulders, a weight she didn't even know she carried.

Kara tapped her chin, looking upwards for a moment in thought.

"I always was?" the Kryptonian said after a few seconds, smiling cheekily.

Alex fought the urge to roll her eyes.

A flick to the forehead.

"Ow!" Kara pouted, rubbing her forehead. "What was that for?"

"For being ridiculous," Alex replied, shaking her head in good fun. "And here I thought I was having a mature conversation with an adult."

"If I'm an adult, then that makes you a saint."

Alex raised an eyebrow.

"A saint?" she echoed. "How do you figure?"

Kara shrugged. "Saints are dead-"

"Undead," Alex interjected, pointing at herself.

"And they've done a lot of good things in the past," Kara continued, unphased.

"Done a lot of good things?" Alex echoed, raising an eyebrow. "Hardly. Though if I am a saint, that would make you… an angel?"

Kara narrowed her eyes.

"Oh wait!" Alex almost snorted, her vampiric features having reverted to their human counterparts at this point. "You are an angel!"

"Aleeeexxxx," Kara whined, hanging her head. She face palmed. "No. Just… no."

"Oh c'mon, I thought that was funny," Alex said grinning.

"Aleeeeeeeexxxxxx."

"Alright, alright," she said, raising up her hands in defeat.

Letting her hands drop to her lap, a funny thought came to mind as Alex smirked at her sister.

"Did you hear the joke about the saint who greeted an angel at the gates of Heaven?"

For that question, Kara tackled Alex to the bed sideways, the two of them bouncing up and down on the mattress a few times before breaking out in giggles. Her legs hanging over the side of the bed, Alex reoriented herself so she could lie on her back, Kara soon after snuggling into her side, her head on Alex's shoulder and an arm draped over her stomach. Alex wrapped her arm around Kara's shoulders.

"Blood or not," Kara said once they finally settled. "Human or not, you are my sister, and I need you. I will always need you. You know that, right?"

Looking down to see Kara looking up at her so earnestly, Alex reached out for her sister's hand and intertwined their fingers together.

"And I'm here," she said, Kara's smile mirroring her own. "Always."

"Good," Kara said, tucking her head under Alex's chin. She cuddled against Alex some more.

"Just so we're clear."

A/N: Had a bit of trouble writing this second half. Wanted to write/explore so many things, but again, could not fit everything in here. I suppose that's just further incentive to finally write a multi-chaptered story about this, huh? XD

I think the show does a really great job at showing the heart-to-hearts between our favorite Danvers sisters, even between Maggie and Alex. As such, I tried to capture that same feeling here. Not sure if I managed to do that or not, but it was worth a try. Lol.

Some of you may have noticed I've used a few lines of dialogue from the actual show's episodes in this piece. I couldn't help myself. Some of those lines just fit so well! XD

For those of you wondering about the saint angel joke, it was actually an angel joke I modified for my story's purposes. It goes like this:

Q: How do angels greet each other?

A: They say, "Halo!"

And last but not least, who's excited for Supergirl Season 3? I am! That Season 3 trailer was awesome!
