"You can't spell SLAUGHTER without LAUGHTER!" ~Pinkamena Diane Pie, Cupcakes.

So as the bodies began piling, they began to take their tolls on the Sinister Six. For Pinkie, it was lack of sleep. Sure, the one more likely to suffer this is Twilight considering her mental breakdown in the time travel episode, but Pinkie's been known for being the happiest and going to sleep knowing the next day was a new day. Now ever since the death of Rarity, she's been more scared than happy. She jumps whenever she hears doors open now, even jumping high enough to reach the ceiling. She began spending with her "friends" again from Gummy's party like Rocky, Mr. Turnip and more. And she slept with the lights on or try to train to sleep with her eyes open so she can dream and watch reality at the same time. Before you say that's impossible, it's Pinkie, don't question it. So why is her hair not straight and still poofy? Well that's normally when she's sad. It did droop at one point but she had hopes of being happy once she helps the rest of her friends find the killer to bring them to justice. Plus, she had too many happy memories killing others, it made sense her pleasure in committing murder eventually overpowered the death of her friends. To them, the team relied heavily on variation. Each killed differently, each named themselves differently, each used their symbiotes differently and each reacted to their personal tragedies differently:

Fluttershy took it as a sign of warning. That's why she jumped to her guns or rather her spear and turned her once happy cottage into a crude ironed fortress with traps and spear in hand. She unfortunately didn't cover everything in her home and wasn't perfect so when she dropped her spear, it became the shovel that dug her grave.

Rainbow Dash didn't go around and crying sad. She just dust her shoulders off and tried to keep on moving. She didn't want the past to affect her present, hence why she also didn't want to have Blitzing Speed in her home and instead have him out of his life forever. Sure, Scootaloo meant a lot to her, but people change overtime, for better or worse. One moment, a guy you knew all your life cared for you as a friend, the next you're on the floor covered in bruises with that "long time friend" of yours just watching as he was too scared to help defend you now. This ignorance of the past rather than reflect or adapt to it is what led to her demise by the mysterious murderer as it came back to bite her in the form of the cloud drop and electrocution, not just as a sign of karma.

Applejack also thought ignoring the past and focusing on the present would make her a better person. In her eyes, her wanting to end the life of Flammy right now was more important than the killer out there hunting her and her friends. The death of her family hit her harder than her companions.But when the truth was revealed in a form she didn't expect to be, finding out Flammy didn't kill Applebloom and Flammy's life has been shitty to say the least, she forgot the other unsolved problem so the figure came by to remind her and thus, she got killed because she wasn't there at the meeting. She tried to talk her way out of this knowing the true side of Flammy, but since Flammy then knew of AJ's true side too, she made Applejack pay for it in death. Just like Jack said. An eye for an eye, and a bloodbath for a bloodbath. She thought she was gonna be bathing in Flammy's blood but it turned out to be her own. And the temperature to the bath was set to be 450 degrees Fahrenheit.

Twilight and Pinkie were the only ones left to actually try to stop the killer once and for all.Not only did they see what happened in the past but they tried to adapt to it too. Rarity's death was a surprise, Fluttershy's death a day later was caused by the defenses being brought up too late, and Rainbow Dash and Applejack's deaths were the result of blissful ignorance. The two remaining friends decided that to prevent falling into their categories, they should set their subtle home defenses during the day as well as stay together. Unfortunately, they should've been concerned about their well being at first, as seen by Twilight needing to go eat.

Twilight also brought up a point when accusing Pinkie right away that she killed Rarity. The killer is someone who knows them all greatly. It's someone who knows they all are the Symbiote Six. It's someone who refuses to kill in plain sight in the day but at night when they are usually the Symbiotes. She should've realized that it must've been someone who believes killing is wrong in the sense of killing the innocent, but killing ones who deserve it is logical. Why would the likes of Spike still love Rarity when he's aware she's descended to a cold-blooded murderer alongside her friends? He tried to stop her when she did go crazy before, so why has he dropped his gun now and embraced her instead? Especially since he didn't kill anyone nor was fused with a symbiote? Twilight in this universe is of course a psychopath who can easily hide her true nature, but her way of seeing good and evil is forever tainted. She still had a certain blind spot that the killer managed to exploit in the form of her unexpected death by microwave. With Pinkie or should I say, Slaughter the only one left standing, lets see what she'll do against the killer literally staring at her through the security cameras:

Pinkie woke up from her inner fight between staring at the security cameras all night or taking at least a nap. The nap won and as she awoke, she finally spotted the killer: At the kitchen where she was supposed to watch Twilight and Spike, she now sees Spike smiling menacing at her with Twilight dead behind him. She sees him just in time to hear him say out loud:

"Five down, one to go. We meet again, Symbiotic Six. Signed, Spike."

Then the camera went static and Pinkie slammed her fist on the desk hard enough to break the table in two as well as a lot of monitors in the fall. She then busted through the crystal wall, pulled out her megaphone and yelled:

"ENOUGH IS ENOUGH! SPIKE, I CARED FOR YOU FOR SO LONG! NOW IT IS TIME YOU PAY FOR YOUR CRIMES AGAINST ALL OF MY FRIEEEEEEEEEEEEEEEEEEEEEENNNNNNNNNNNNNNNDDDDDDDDDDDDDDDSSSSSSSSSSSS!!!"

The force of her screams spread throughout the castle, blasting several doors open, shattering the bulletproof windows, and making all the guards outside fly hundreds of feet away. While it was indirect, no distractions should get in way of Slaughter this time. It's 1 to 1. She then took several big breaths of air, dropped her microphone and got into a fight pose as she could hear the big stomps of a certain dragon coming this way. She could also hear a long squeaking noise, but it doesn't matter now. Spike dying is all that matters in her mind now. She then saw what was coming this way: Not only a still bloodied Spike, but in his big claw was the corpse of Twilight being dragged this way. Maybe he considers her body as his trophy? He does come from a greedy and rather heartless species, maybe it's starting to show now.

Now's not the time for staring though. Slaughter got to work, spraying various amount of goo at Spike so many times until he got stuck and essentially glued to the wall behind him. He tried to move his arms but they were trapped inside the main red-black blob on his chest. Slaughter then tried to draw first blood by aiming to slash his exposed neck, but it proved to be more difficult than anticipated. Then again, she should've known as it's a human with organic claws vs. a dragon. She kept on going anyway, not wanting to give up on her progress until she saw Spike begin channeling his fire breath and unleashed it. She quickly did a backflip to dodge it, only to notice he didn't do this to fire her, but burn the goo away. He then gets off the wall and boasts:

"What's the matter, Pinkie? You hate challenging prey? I'll do more than be a nuisance!"

He then gives out an extreme power roar to rival the one Pinkie did a while ago with her megaphone which sent Pinkie flying several feet into the crystal wall behind her, but she quickly got up and hissed. She then pulled out a big slab of goo from her body and constructed a giant thick sword from it. She ran up to him and tried to cut his legs off but he quickly jumped up and blasted another fire breath at her. She quickly ran around the corner into a room near her to avoid the flames catching onto her symbiote as it did manage to burn the sword. She then replied loudly to him:

"I don't hate challenging prey, Spike! I'm just getting used to it and so far, you're putting up an awful fight! I'm moving faster than you!"

"Speed isn't all that matters, 'Slaughter'. Did you forget my strength?"

He proved his point further by smashing the crystal wall she was hiding behind, causing her to be crushed by blocks of rubble. He didn't see her in the pile so he assumed she ran off somewhere and began looking around the room to search. He's got his back to her. Perfect for Slaughter, who jumps out of the rocks and begin climb up his back. She did notice this weird stream of blood on his back, but that doesn't matter. He felt her there and tried to grab her, but Slaughter dodged every one of his grabby claws. He then tried to fall on his back to crush her but before he made it the ground, she fell off and landed on the floor just to then jump on his face. She resumed to making him miss her so he resorted to opening his mouth and try to bite her in half, but despite his formidable jaw strength against gems, that symbiote's too tough to break. He then remembered his flame breath and began firing it up but she then jumped up before he repeated this attack for the third time and went up to his eye. He tried to punch her off but she jumped out of his incoming claw to end up stabbing himself in the pupils, making him unable to see. As he tried to cover his bleeding corneas, Slaughter then blasted goo at his face to make his hand stuck to his face, but he still tried to swing at her blindly with his other arm and tail. Eventually, he fired a flaming ball into his hand to free it and pull out his fingers, but Slaughter also noticed on the ground were not just his blood but also two punctured corneas and up there now were pupil-less eyes which he quickly closed them to stop the blood gushing from them.

That's it, she said to herself. She has to get to his squishy insides like his brain, but the only place big enough to let her go into now are those eyes. His mouth's too risky considering his flame breath, so she'll have to get up there. He wasn't trying to go down that easily so despite being blind, he began punching, clawing and roaring at the air in front of him, hoping one of his hits would strike at Slaughter and knock her out to burn her to death like Pollutant. Good thing his back's still exploitable so she fired a goo rope to the ceiling, launched her way up and dropped onto his head talons. She then forcibly open his eyes and made a chilling discovery:

Spike's eyes are always green. and had slit irises. But the eye that was now in its place were blue and had normal irises. Just like... hers. Wait a minute. Framing her out of all the Sinister Six, bearing a grudge against all of them, killing them only based on their names, having seemingly impossible ways to get in and out of sight, knowing where all of them live or went, saying it was not dead and hiding the shadows... It's not Spike the Dragon in front of her. IT's wearing his skin or took over his body. That's why that bloody trail is on his back. So that means its...

"Spike" then slashed her off and breathed another ball of fire to burn her symbiote and her but she didn't die. She's alive like RD but severely hurt. "Spike" then says, "It's time for you to get a good look at... yourself." The dragon then collapsed and his back splits open, releasing gushes of blood everywhere. Something then jumped down. It was pink and had those very same blue eyes. It was Pinkie Pie. ANOTHER Pinkie Pie. One who was also nude as well. It then approached the burnt Pinkie and put her foot on her crispy chest.

"Hello again Pinkie Pie. Did you miss me? I had the heck of a time tracking you down after beating your friends. It was... FUN!" This Pinkie exclaimed gleefully, showing her big, bloody smile.

Pinkie's burnt eyes widened as she did connect the dots already. She explained, "You. You're one of the clones."

The nude Pinkie nodded and explained, "The one that got distracted by Rainbow long ago when she said, 'Somebody's making balloon animals'. It wasn't easy getting out of that fucking Mirror Pool. I felt myself melting and losing shape as I punched for dear life to get out but eventually I had the sudden amount of force to escape and my body reformed to look like you again. I was filled with less happiness at that point and filled with rage. Rage that you and your friends figured we were a threat to your kind and thus, it's best to put us back in that hellhole world we used to live in and not be free in this one. That's why we were so eager to go around and be you. We finally felt freedom, we felt hope, but then everyone got sappy and wanted us back in there. I even had to spend a harder time pulling out that boulder at the entry to the pool. Who put that there? Applejack? That doesn't matter. I wanted to come back to you purely for my revenge. But the more I heard about these "Sinister Six" and realizing they were YOU and the rest, my plan changed. I knew if I went to you right away, they would come after me and put me back in the pool. So I instead took my years planning out my attacks carefully on each of your friends, starting from weakest to strongest. That's why I saved your friend Twilight for last as if I took her out, the others could've brought other magical friends involved and thus, I would need to kill unfortunate sods trying to protect ones who don't deserve such thing. I also got some of the family involved to keep track of your movements. Applebloom, Blitzing Speed, Spike, Flammy, the Cakes. All of them were involved. You and your friends thought telling them your secret identity was a good idea but in reality, who would want to support their heartless, genocidal family members? They still had hearts, you all lost your own. So you're the last woman standing. Or rather on the ground, ready to die. So any last famous last words, Pinkamena Diane Pie?"

The burnt Pinkie was so mindblown by this unraveling of a mystery, she didn't know what to say now that it's her turn to speak. There was no way out of this though, so she simply muttered, "Just finish me and get over it."

The nude Pinkie answered, "Gladly" before tearing into the crisp Pinkie's flesh with her bare hands. She broke several ribs, ripped out several organs and basically made Spike's corpse nearby no longer the only one surrounded by a blood pool with guts. The burnt Pinkie simply watched until eventually, the nude Pinkie clone tore out her heart, abruptly ending the life of the real one. The clone then dropped it and crushed it with her foot. It then spun around to rid itself of all the blood and began walking out the room, down several hallways, out the back door of the castle and walked all its way to the forest, never to be seen again...

The End.

Author's Note

In case any are confused. Here's what happened:

The week went like this:
Monday: Late at night,The mane six kill off Scootaloo to show how they're like in Bloody Introduction.
Tuesday: Late at night, Rarity's decapitated body was found.
Wednesday: Late at night, Fluttershy tried to forify her home and trap it up to end the clone Pinkie once and for all, but died.
Thursday: In the morning leading up to noon, RD got her "accident" at the factory and was sent to the hospital. The coma she was in from her injuries made her wait until the night came for her to wake up and soon see the clone Pinkie there injecting a poison into her blood, killing her. That's why the clone Pinkie removed her hood, she simply said she was the actual Pinkie going to see RD to if she's awake.
Friday: (Maybe nearby it should've said it was the 13th): Late at night, Twilight and Pinkie try to have a last stand against the mysterious Pinkie Clone, resulting in the Pinkie Clone winning and vanishing to avoid being caught.
