Watched a little bit of Doctor Who, got inspired and voila!

Bet you didn't expect me to update it this quickly, huh?

Begin!

You're Just A Parasite!

Cadance Pov

"GRAHHHH!"

The roar that left my lover's mouth shook not only myself, but the very walls and ground around me. The windows splintered and cracked, some completely shattered.

This was all second notice mind you. I was far too busy struggling to keep him still as ponies around me attempted to strap him to a stone bed. My own pink aura was mixed with Celestia's brilliant gold, but as they flickered and died, only to reappear and struggle once more, any awe I might have had vanished very quickly.

A young Pegasus, a doctor, ran up to Alex and attempted to keep him down with his body, gritting his teeth as he was shook and nearly thrown off of him.

"SIR! You need to calm down, we're not going to hurt you, we're only trying to hel-SHIT!"

My focus over my magic nearly died as I witnessed a stream of purple fire escape Alex's mouth, almost washing over the Pegasus as he dived to one side.

"Somepony get over here and help me hold him down!" he yelled, three stallions and a mare of the guard obeying as they each clung to a part of his upper body. Chest, arm, shoulders, all was held steady as can be as two doctor's frantically attempted to tie his limbs in restraints.

"AH THE PAIN!" the cry escaping my mate's muzzle tore at my heart. "Someone stop the p-p-p-AHAHAHAHA!"

Bloody tears began to leak from his eyes, more dribbling from his nostrils. His entire body was shaking with such a force, that I thought with no uncertainty it would fall apart.

When foam began to form inside his mouth however, that's when I lost all remnants of self-control and screamed to the high heavens.

"SOMEPONY HELP HIM!" I cried, desperate tears, fearful tears falling down my face as my magic flickered and died.

"We need a sedative, now!" my aunty ordered, her own voice powerful and authorative despite the distress clear in her expression.

A mare in a lab coat seemed to burst into the room at our calls, a syringe hovering in her aura as she raced over to my poor Alex. As if knowing what was to happen, my baby snapped his eyes…his terrible, slitted eyes onto the mare and grinned a mad, foaming, malicious grin.

The syringe wielding mare froze on the spot.

"Can you HURT him?!" the voice that escaped his mouth was not my beloved. It was too cruel, too insane to be of kin to one of humour and sarcasm. "Will YOU?!"

A righteous fury burst from within me at this…this THING. My instinct, my own inner power rose up within me, empowering my confidence, my love for the man weeping as this horrible being grinned through him.

"Get out of him!" I screamed, my eyes alight with power long unfelt.

The thing cackled madly though its insanity, foam dribbling from my lover's mouth and onto his ripped gown.

"Why should I?" it laughed, body shaking from convulsions and sick humour. "He is mine! You have no say, mate thief!"

Mate thief?

The thought comes as quickly as my rage erases it, taking control of my actions as I push away the stallion atop his chest and lay myself atop him, baring my teeth viciously as I grasped my poor baby's head and stared right through his eyes at the…malevolent being inside him.

"No," I whisper, the word barely forming through my fury. "He is mine, my mate, my lover. Whoever…whatever you are, YOU have no say. YOU will leave my Alex alone, or I will drive you out of him and rip you apart,"

The grin on his face, the grin not his own only seemed to widen at my declaration.

"On your own?" it chuckled, a gleam shining through Alex's eyes. "You are a child, fighting against those so much greater than yourself. Do you truly believe that you can separate us, alone?"

I make to growl out a respond, but before I can do so, a very quiet, very furious voice beats me to it.

"She won't be alone," Celestia utters, her rose colored eyes now a very bleak shade of grey, flickering between that and pure white. "You have invaded my son's body, violating both it and his mind in the process. No, she won't be alone. I will rip you from my little colt's body and banish you into the endless void for what you've done to him."

My aunty waved away the doctor's, the frozen mare following suit a mere moment after she was released from whatever had taken hold of her. The mare of the guard however, stayed.

"Will you now?" it spoke, surprisingly lacking in any emotion. "The endless void, is it? Was the moon not good enough for me sister?"

"Sister?" I echo, glancing back at my aunty and taking note of her shocked expression.

"Luna?" Celestia whispered, her horn lighting up as she aimed it in the direction of a shattered window.

"Did she not tell you, foal?" it...or Luna laughed, quickly recapturing my attention. "I found him before you even existed. He loved me, and I him. But dear Celly couldn't handle the idea of her 'baby sister' loving more than just her. So she took my beloved Xander from me, and banished me when I tried to bring him back!"

These were words my aunty had more or less told me before, but to hear them from the apparent mare herself was…still surprising. Though what was more were the very words to escape Celestia muzzle not a moment later.

"Do you still have that blanket with the half-moon emblem, Cadance?" she asked me, her eyes narrowed in undeniable anger.

"I-I think so," I replied, the pure light of my eyes dying down to normality as I climbed off of my lover. "It's under my…our bed."

Celestia nodded to the mare of the guard straight away, said mare apparently understanding what was to be done as she sprinted out of the door.

"Aunty?"

"It's alright Cadance," she said, tone as soothing as could be in that particular moment. "I believe I know what has happened to Alex."

Before I could inquire as to what, the guard returned with the familiar blanket from…our picnic some time ago, and laid it out before Celestia. My aunt took no time in…what I believe to be scanning it as she ran the tip of her horn over it.

"What do you seek to accomplish here sister?" Luna demanded, spittle flying from her…Alex's mouth. "There is NAUGHT in that blanket that can separate us again!"

"I thought so," Celestia muttered, ignoring the loud voice as she rose and regarded it…with an expression so cold that frightened me.

"You thought what, sister?" Luna spat, paying me not so much as a glance. "That you can finally see beyond your own reflection?"

Celestia didn't answer the jeer, choosing merely to keep up the icy expression.

"Celestia?" I spoke, almost flinching as her expression snapped onto me…before thankfully warming up a touch.

"Apologies my dear," she replied, smiling a small smile. "Allow me to explain, if you will?"

I nodded slowly as she came closer, looking at my beloved as gestured towards him.

"You," she spoke, a shocking amount of venom in her voice as she glared at those slitted eyes. "Are nothing but a powerful echo of my sister. A parasite, clinging to his life force to stay alive."

'Luna' sneered at my auntie's explanation and shook my honey's head.

"I am no pale reflection!" she snapped. "I love him as much as the day we first made love. I remember each touch, each wondrous sensation. And I have made him powerful, I have given him magic most mortals could only dream of having!"

"We are not Gods," Celestia refuted. "And I never named you weak, I can sense the power you foolishly, cruelly forced into his very soul. Do you truly believe that one who once defied all magic could grasp the fundamentals of controlling it?"

"I will teach him how," Luna growled…oh by the gods, the loving, sickening smile that crossed my lover's face. "As I was planning on doing before he killed himself and returned to reality."

"He killed himself?!" I screeched, wings flaring in horror and fury, Celestia's sudden hoof and shake of her head the only thing stopping me from…doing something!

"Just like I told you Cadance," she soothed, left eye twitching ever so slightly. "Only an echo, with none of the compassion or sanity my sister had."

She looked back at 'Luna' and regarded her, once more, with an icy expression.

"I remember Luna's joy when she befriended Xander," she continued. "I remember the love in her eyes that I unthinkingly believed was because of me. And I remember how she glowed when she told me of her plans to share her divinity with him.

"I do not know what you did to make my child so afraid, but you…you are only a frail image. And once I find the correct spell to do so, I will banish you to the darkest corners of this world. Where nopony will ever hear you scream…"

Aunty…

It's moment's like these that remind me just how much Celestia loves Alex. And if my instinct, our Alicorn instinct reacts when the one we love is in danger, then how my poor aunty is managing to hold her own back after I all but let mine flare to the surface is beyond me…

Her self-control is awe inspiring.

'Luna' narrowed Alex's eyes at my aunt and sneered defiantly…before the body she inhabited became limp very quickly.

Said eyes returning to the green I love so much.

Unable to restrain myself, I rushed forward and grasped his face as gently as I could, his eyes completely unfocused as I looked into them.

"Alex, honey!" I spout, panicking as I get no response. "Baby please wake up! It's me!"

I make to press my lips to his, only for a golden barrier to come between us. Unthinking, I snarl at the perpetrator and flare my wings in an instinctive show of protective dominance.

Only to realize that my aunty is the one I'm 'protecting' Alex from.

"What…what are you doing, aunty?" I ask…demand.

"Protecting you from the parasite," she explains, eyes narrowed yet worried. "Do you remember what you told me about before this all started? That something left you and latched onto Alex?"

Blinking somewhat dumbly, I open and close my muzzle several times, glancing back at my little snuggle honey and trembling at Celestia's implications.

"A-Are you saying that I c-can't even…"

Sadly, she shakes her head and comes a touch closer, eyes and tone firm as she says…

"No Cadance…you can't kiss him," she affirms quietly. "In fact until I've found the spell to banish the remnant of my sister, I would strongly advise that you limit how much you touch him without me here."

"I can't even comfort him?" I whisper, my eyes filling with tears as I feel my body try to defy this order.

"Not without me here," she says once again. "If the parasite latches onto you without me here to protect you, then there would be nothing to stop it from killing you and returning to Alex."

Of course…Luna 'found him first' and I'm just the mare that stole him.

I didn't believe it, I didn't believe it for a second. Alex was my mate, no one else's.

And the fact that I couldn't comfort him…the way, the amount in which it hurt me was…astronomical.

"I don't care about myself, aunty," I growled, gritting my teeth as I fought off angry tears and looked up at her. "I just want…no, I need to hold him…please…"

Aunty looked down at me, pained. Her muzzle was scrunched up, frustrated and angry at my pain…I could feel it.

And after a few moments of apparent contemplation, she looked over at my Alex and lit up her horn, his entire body soon following.

"Be quick," she said, her breath shockingly ragged as she gestured over to him. "I'm projecting myself onto him, no dark reflection can pass this kind of magic easily."

"Soul magic," I whispered, more to myself than her, though she nodded nonetheless.

Snapping out of my thoughts, I clambered onto the stone bed and gently laid myself atop my lover, reaching down with my muzzle and-

"No!" Celestia gasped, shaking her head rapidly. "Soul magic…might not be enough for that. Just…only touch…might break through with lip contact…it's an ancient magic of its own...could take advantage and…"

Fighting off evident fatigue, my aunty closed her eyes and kept up her slowly spluttering horn, tears slipping down her face, though from exhaustion or morose depression I couldn't tell.

Whimpering quietly at the denial, I leaned down to my lover's face and…kissed his forehead with as much love as I could possibly give, before moving back and burying my face under his bloodied chin.

The simple familiarity of his scent being defiled by coppery blood was enough to almost break me down. That such wrongness could mix with something so beautiful was horrifying.

"C-Cadance…"

Body shaking as I willed myself to move, I removed myself from the familiar comfort of his heat and backed over to Celestia. The mare in question let go of the exhausting magic and almost collapsed on the spot, but with sheer determination somehow managed to stay upright.

But as for me…I couldn't stop myself from burying my face in her chest and finally weeping bitter tears as I broke down.

It had been a month since my beloved collapsed. A month in which I was completely alone…unable to touch him while the doctor's tried to figure out what was wrong.

I could do naught but sing…and hope he heard it somehow.

"I will save him Cadance," Celestia soothed, nuzzling and kissing my head tenderly. "I promise, just try to hold on. Then we can both snuggle him back into the hospital, okay?"

I chuckled weakly at her little joke, but appreciated it all the same and nodded.

"I've never seen him so scared before," I mumbled sadly. "It frightened me."

"I know sweetie," Aunty sighed, looking over at her son. "It frightened me too."

Author's Note

Done.

Short, but it's all I could really think to write for this particular part. I don't expect this story to be long, but I know it'll have just the right amount of drama and fluff to keep you guys appeased.

Til the next chapter!

Cya, stay snuggly!
