Light and Dark

Chapter 13

Cara's P.O.V

I sat behind the wheel of the truck as I sped down the highway towards Kensi's old apartment in Venice. "Cara I know what you are going through but a car accident will not bode well for either of us." I glanced over at Alex and saw as he grabbed the 'Oh Shit' handle. I let up on the gas and slowed down, but I was still speeding.

"I'm sorry. It… I just need to protect my sister, since I failed ten years ago." My voice was barely above a whisper.

"You did not fail, and I highly doubt Kensi blames you. Look at it this way Cara; If you hadn't shown up at he place she would have stayed with Jack, and she never would have met Deeks. She would be unhappy and a shadow of herself, her wolf would practically be smothered. And when Jack escaped it gave her room to join NCIS and find a family who was human and let her thrive and grow." His voice was soft and understanding.

"I never thought of it that way. Either way this can only end one way; with Jack's death." I said as I pulled into an abandoned apartment complex. "After the ordeal with Jack people started moving out and eventually the owner sold it to the banks. It has sat untouched for near 5 years."

"Lead the way Cara."

We walked up the stairs leading to Kensi's old apartment on the third floor. I had an unsettling feeling settle deep within my chest. Opening the door I was met with an air of musky scent. "I will take the bedroom and living room, you take the bathroom and the kitchen, but be careful for all we know he could have rigged the place." He nodded and took off.

After a half hour we conceded that there was nothing there. "Something isn't right," Alex said scratching the back of his neck.

I was about to say something when I doubled over in pain. I felt as though every nerve ending in my body was on fire and freezing at the same time. It shot me back in time to when I was 15 and went through the change for the first time. My scream of pain tore Alex's attention away from the apartment.

"Cara! Cara what is wrong?" his voice was panicky.

"Kensi, something happened, we have to get back to her something is wrong!" I plead.

He guides me to the truck and put me to lie down in the backseat. The whole ride back to the mission I writhed in pain. A scream of pain escaping every now and then, I hated to think about why Kensi was feeling such pain, pain that I hadn't felt in over 15 years.

As Alex pulled into the mission I limped out of the back not waiting for my husband as I stormed inside.

The first thing I could smell was musk, a smell common in wolves, the next thing I could smell was blood, and a lot of it. a cold blooded fear settled deep within my heart when I saw a wolf identical to mine, breathing heavy, standing over a small pool of blood.

Kensi's P.O.V

Walking down to the bullpen I all but growled in frustration, "I hate feeling useless while my sister is out there working the leads."

"Hey none of us like it any more than you," Callen said. "But Cara was right when she said that we don't know how to deal with a vampire. At least Nell and Eric are being helpful."

"But that is the thing, I know how to deal with a vampire, I have since I could hold up my weapon." I snapped. Sitting here was starting to make me antsy and irritable.

"True but you and Deeks are the main target of Jack, going out there makes you vulnerable." Sam reasoned. I knew that he was right but that didn't mean I had to like it, and I didn't, in fact I hate this, filling out paperwork on my day off while my sister played the knight in shining armor. I could take care of myself Damnit; I have since I was 17 and father died.

I slammed my fists down on the desk and made my way to Hetty's office. As I approached I noticed that my boss did a double take. "Ms. Blye, I fear that I have never seen you this… how shall I say pissed off." He voice was light but her eyes gave he away, she was worried.

I sat down unceremoniously in one of her finely decorated chairs. "You're damn right I'm pissed off. I feel like a sitting duck Hetty. I hate sitting here and doing nothing while others do all of the work," I started rambling. "And I know that my sister is protecting us, but Damnit sometimes I feel as though she is babying me, just because I have yet to change." I took a deep breath, feeling some of my anger dissipate, but it was still there churning like a raging ocean.

Hetty sat back and clasped her hands together as she looked me over. "Ms. Blye I have always known of your sister, and knew what she was, but you I could never tell. You once said that a transformation, whether early, like Cara's, or late, as it seems yours is, is painful. Perhaps she doesn't want you to go though that so she is keeping you from any situation in which she thinks that the wolf within you will see absolution." She paused but I knew that she wasn't done so I remained silent.

"If I may speak freely of you and your sister?" she asked.

"Of course Hetty."

"It seems that you and your sister are… special. Your mother's wolf is weak, yes?" I nod. "And yet, Cara's wolf is strong, yes?"

"Yea, she is, she is taller to, most wolves stand about 5 to 6 feet. Cara's wolf is nearing 8 feet. She is faster, stronger, her senses are shaper, and she has an air of command about her, it is why she is Alpha."

Perhaps there is something in you and Cara's blood that is special. Now I am but a simple human but I have come across several gypsies in my day and I remember a story on once told me. Would you like to hear?"

"Of course, please." And so she begins telling me a story that mystifies me.

"In ancient Rome, vampires reigned. They tore down Ancient Greece, small city states but all lead by Werewolves. Constantine, when he was emperor, brought Rome to a peak, but he was plagued. For he was not a vampire and thought that the eradication of the wolves was wrong and unjust, but he could say nothing for he knew that he was no match for a vampire, even though he was a solider. One day while he was traveling through Constantinople, a new city that was a wolf stronghold before it was conquered, he saw a young woman. Clearly she wasn't a wolf for all of the vampire sentries were walking right pasted her, not giving her a second glance. The woman, clearly homeless and starving, caught his eye, for she was beautiful. What caught his attention was not this dirt covered beauty, no it was her eyes; one grey on black."

I was staring intently at Hetty and gasped audibly when I heard the description of this mysterious woman. "Like Cara's." I stated.

"Yes. He knelt next to this woman and he asked if there was anything that he could do, or if she could tell her who she was. But she was mute, he tried to take her back to his tent for a meal and bath but she adamantly refused, when he asked why she merely said 'I cannot leave my sister' he looked around but saw no one, until she pointed to an ally and pointed to an exact copy of the woman sitting before him, this woman however had one hazel eye, one black."

She paused, clearly letting me absorb this information, the people she was describing were me and Cara, merely two thousand years prior. I was confused, but I remained silent, letting her continue.

"He said that she two could come. As he led them back he watched as they quietly ate, clearly hungry but maintaining manners. He asked if they knew who their parents were. The two mysterious women shared a look, one of sadness and fear. He told them that they could trust him. The grey eyed on spoke…" as Hetty spoke I closed my eyes and pictured her words.

"Our parents are now outcasts, I fear that trusting you, Constantine, is not wise for us, for we value our lives." Her words were cold and calculating.

"I can assure you, I have no intentions of harming you, were your parents' werewolves?"

"No." the hazel eyed one spoke.

"Well can I at least have your names? We can then go from there." His words were soft, calming the hazel eyed on, but the blue eyed one fixed her cold glare on him, sending fear shooting through him.

But finally she spoke. "I am Aegle." He knew the name to mean light in Greece.

"And yours?" I asked the hazel eyed one, she was quiet, but held the same threatening air that he sister did.

"I am Mávra." And he knew this meant dark to the Greeks. A balance, he wondered, between the two sisters, though right at that moment the names seemed switched, for Aegle's stance towards him was menacing.

"Both Greek names, please I have no qualms against the Greeks." He knew instantly that he had chosen the wrong words, but this time it was Mávra who spoke.

"No qualms, really? Is that why you all but destroyed Greece, is that why our people, our parents are no more!? Is that why our cousin was murdered for merely being herself?" She was shaking in anger by that point, and when Aegle set a soft hand on her shoulder did she calm down, but barely.

"I am sorry your parents are dead…"

"They are not dead," Aegle stated, her words laced with venom.

"Then where are they?"

"Just as she said, they are no more. They no longer exist."

"Please," Constantine pleaded. "I don't understand, I just want to help you."

Mávra shook her head and stood and stalked towards him, she clearly resembled a wolf stalking its prey, and he wondered if he made a mistake and these two had found a way to hide themselves from the vampires. "We, your majesty," she spat. "Are not human."

"You're wolf?"

Both sisters smiled, "Partly, however wolves are human, they just have a unique ability, we" she gestured to the space between her and Aegle, "Are not human. Not an ounce of our blood belongs to the being known as man."

"Please, Mávra, sit and let me explain." Clearly Aegle was the voice of reason, with a temper.

"What my sister is trying to say is that are parents, were gods. Greek gods, we were conceived and born before they faded from existence."

He sat there looking from each set of eyes. "Which ones?"

"Athena, and Poseidon."

"Both major gods," Mávra said, her voice filled with sadness. "It was your people who contributed to them disappearing, it is your people who made us outcasts." He voice was deadly calm.

"Your names, light and dark, what does that mean?" he asked, he knew that one day is curiosity was going to get him killed, it just so happened that that was not the day.

"Exactly what it means, apart we are strong, and together we are unstoppable. Vampires will come to an end; it is for the good of the world."

They both sat up simultaneously and with snarls they both transformed before my eyes in a gust of wind. Constantine had seen many wolves in his travels, but these two, they surpassed all of them, and these were war machines.

They bounded out of his tent into the night, the yells of the sentries sounded through the night. Then the yells were silenced and two strong, sad, vengeful howls sounded through the night. Whether it was now or then Constantine knew that the age of the vampires wouldn't last forever, and that made sleep come easier for him, all the way up until his death.

When Hetty finished I could feel my pulse racing. These two women, Aegle and Mávra, they were me and Cara, I could feel my chest constrict. "I-I…I don't un-understand." I stuttered.

"Perhaps it is just a story, or perhaps this is lineage that explains the reason you and Cara are different than the others of your kind. Perhaps this is the age where vampires meet their end."

"Light and dark…" I whisper. "Cara is light… and I am…" Hetty walked around the table and put a finger under my chin, making me look at her.

"Do not jump to conclusions. Think of it this way, with your delayed change, you have found a peace within yourself, you have morals that perhaps Mávra didn't, the delayed change could be your time to find yourself and what you stand for, using the dark for good." Her voice was soft and gentle.

"And Cara?"

"I do not know her well enough to answer that, perhaps through history the status quo of Aegle and Mávra could have changed with you and your sister, perhaps, together with a level head and just heart this threat could end."

"That was a whole lot of 'perhaps' going on Hetty. But I think I understand. How did this gypsy come by this story?"

Hetty smiled at me, "She said it was passed on through her people, those of the town where Aegle and Mávra resided before it became Constantinople. Now go dear, we should expect a call from your sister at any moment to let us know what she found" she patted my shoulder before I got up.

Deeks was waiting for me with that smile that warmed me inside and out. But when a gunshot rang out his smile disappeared as he lurched forward. In slow motion I could see the bullet exit his upper leg. Everyone in the Mission drew their weapons. As Deeks fell to his knees I saw him, for the first time in ten years with my own eyes.

"Jack." I whispered.

"Hey darling," he said as he raised the gun towards me. I felt a bullet rip through my upper shoulder as I fell roughly backwards. I heard Callen and Sam let loose a hail of bullets on Jack but none touched, then silenced.

"What they fuck why can't we move!" Callen yelled.

"Stay away from her!" Nell yelled as Jack leaned over me. I too was frozen in place, forced to feel as he ran a hand down my arm, a gesture that from him used to be sensuous but now sent my stomach rolling.

"Don't worry Kensi, it is not your turn yet, for I am merely here for him, but once I get bored of him I will come back for you." he leaned down and whispered so that only I could hear. "Don't let love blind you, Marty is a nobody, he is going to leave you, I will make sure of it." he pulled back and walked over to Deeks.

He forcibly pulled him up by the collar of his shirt producing a yell of pain. "Shall we Detective?" he began walking towards the entrance.

"NO!" I yell trying with everything I have to move but my limbs felt like they were lead. "Deeks!" somehow I manage to sit up and yell one last threat before they disappear. "I will find you Jack! You won't get away with this, I will find you!"

Seconds later after the squeal of tires disappeared could we move again. "Kensi, sit down you were shot!" Callen yelled.

"I'm fine!" And I was the wound was already closing.

"You are not fine!"

"It was a bullet Callen, it is not the first time I have been shot! Do not forget that I am a werewolf." I snap with venom.

I walk over to the pool of blood that belongs to Deeks and I felt something in me snap, contort and tear at my insides. The last time I felt this was when I was 15 and watched as Cara changed for the first time.

I was changing, looking at that blood I felt my wolf for the first time with no barriers no fear. But damn if it didn't hurt. I would rather be tossed in a burning inferno than feel this. I collapse to my knees, leaning over the puddle. I can feel my teams wide eyes glued to me. A scream rips out of me, a scream unlike the one with Chris, no this one was vengeful, this one was full of inhuman anger and pain.

The pain ripped through me for several minutes until I was standing on four legs, I was a replica of Cara's wolf, midnight black fur, fangs shaper than every blade, I was a walking killer. I stood there still looking at the pool of blood, I could smell it now, metallic, but on the air I could also small Deeks, but it was fear not the ocean that I smelt. A deep guttural growl sounded and reverberated through the Mission.

"Kensi." I looked up and saw Cara walking towards me, a hand on her heart, clutching the skin there.

And I realized she was feeling my pain, the physical pain was gone but my heart was constricting as I kept replaying what Jack had done. I looked to my sister.

You have been at this longer, can you track him?

Aloud she answered me. "Yes I can, we will go right away."
