Coco kills Brownie:

"I knew it, Cookie! You only care about yourself! Why do we have to bake cookies according to your preference? Why can't I be allowed to do anything, huh? I bet you didn't care about Angel. I saw how you talked, you only wanted revenge for yourself!"

Coco stops mixing the dough; her whole body perks up. She turns around slowly, not even looking at Brownie. Her whole body shakes, as she fails to say anything for a few seconds. "It's because I'm right" Brownie says confidently.

"Shut...the...HELL UP!" Coco yells, throwing a spoon at Brownie. It hits her in the eye and she screams. Growling now, Brownie lunges at Coco and a fight breaks out. They tumble around, biting and scratching each other, neither caring about the blood that is pooling on the kitchen floor. Brownie has Coco pinned to the floor, "Say that I'm right, bitch!" she shouts.

Coco shows her teeth. "That's right, admit defeat" Brownie says smugly.

Coco reaches into her apron, while Brownie is distracted by the high from her "victory". She pulls out her wand and stabs brownie in the stomach with it. "GAHH!!" Brownie cries, falling to the floor. Now Coco has the advantage. She picks Brownie up and pins her to the kitchen wall by the neck, while the wand glows in her other hand. "C-Cookie...please don't" Brownie begs.

"I told you to stop calling me that" Coco coldly replies. "You think I'm all about myself, but look at you, you sorry puppy. You don't listen to me, yet you say that you love me. I don't think you deserve any of this. I should have finished off with Sparky."

Brownie is crying out of desperation. In a last ditch effort, she sinks her teeth into Coco's arm. "That's it!" Coco shouts.

She raises her wand into the air. It glows brightly and in a flash, Brownie's head is gone. Everything is covered in blood. Coco lets go of the lifeless body, and it falls with a thud. Coco beholds the dead body, and suddenly the image of Angel's dead body flashes in her mind. No...it's not real! It's not real! Coco looks at herself, covered in blood. What even is this...she feels like an all too familiar dalmatian. Purple fur spotted with blood...black and white spotted fur.

"Noooooooo! I'm better than you, Patches! No! No! No! No!" she screams, tears streaming down her face now. She covers her face with her paws and curls up into a ball on the flow.

"Look at yourself now" a voice calmly says. "Get up already you weak kitten" it commands. Coco takes her paws off of her face, she straightens herself out, and looks to her left. A door with a "Home EC" sign right above it, bright blue lockers on either side and caution tape just beyond. She looks ahead; a single grey eye coldly looks back at her. "Face it, you're a murderer just like me. That will never change." swap Patches taunts.

Coco starts to tear up again. Instead of breaking down this time, she becomes enraged. She screams and hurls her paw towards swap Patches. Her paw only meets the a cold, hard surface. It was just the kitchen wall. There is no school, no swap Patches...only just a recollection of a memory...

Patches kills Olive:

Tired of and fed up with Olive's useless responses and advice, Patches gets up, grabs Olive by the shoulders, and slams them against the wall. "T-that hurts" Olive whimpers, while trying to hold back tears.

"Trust me, puppy, that's nothing" Patches says meancingly.

Olive's eyes dart everywhere as their mind races in a panicked daze. They can only feel the overwhelming force that holds them against the wall. Olive starts to breath heavily while still trying to hold back tears. They then feel the pressure remove itself from their shoulders. They can hardly breath a sigh of relief when they feel their throat being restricted. Patches has moved his left paw to pin Olive against the wall by the neck. His right paw reaches into his cardigan to retrieve something. Olive places both their paws onto Patches' left arm to try and break free, but Patches only tightens his grip around Olive's throat. That puts the mutt back in their place, as Patches takes his time to find whatever it is in his cardigan. Eventually Olive sees Patches withdrawing his arm from his cardigan. A pink handle appears, followed by his paw, and finally a shining blade. Olive freezes,"No..." they think.

Patches stares into the blade and smiles. There seems to be something that he sees in his reflection. It's as if he just found a missing piece of himself. He now looks at Olive, who is sweating profusely now. Patches can't do anything but enjoy the fear in Olive's eyes before he slowly begins, "Well, Olive...my dearest puppy...you and Angel feel awfully familiar. Angel was unable to see anything until it was too late. But you...you just never listen...Angel didn't need his eye, since he never saw anything anyways, and since you never listen, you don't need that ear either..."

Patches releases Olive's throat from his grip and steadies one Olive's floppy ears. Olive instinctively bites down into Patches' arm. "You bitch!" he shouts, as red leaks through his sleeve.

He strikes Olive across the head with his right elbow. Olive falls to the ground with a thud. Opening their eyes, they see Patches' menacing figure hovering over them. A little bit of red stains his left sleeve. Olive feels physically weak, so Patches casually straightens the left ear. Olive closes their eyes and feels a small, sharp piercing in their left ear. They try their best to hold back any screams. They dare not move, so the knife doesn't cut anymore by accident. Patches only lowers his knife down, using the tip as a pivot point, so half of Olive's ear has now been separated from their head. He then slowly works through the other half. The burning feeling is so intense that Olive screams and bites on their overalls. Olive can feel the blood gushing out at the place where their left ear once was. They only cry and cry from pain and emotional anguish. Patches looks down at Olive, such a sad mess he thinks, as the pool of red slowly grows around Olive's head. Olive only rolls around, covering the missing ear. "Might was well make it quick" Patches thinks. He stabs Olive in a few vital areas (such precise stab points, due to previous practice). Patches looks at the ear. He flops it around a bit, smiling. "You truly never listen, Olive" he whispers.

He'll clean this all up later, for now, Patches licks the blood stains off of himself. He then heads out the door to put the ear in the jar, alongside Angel's eye.
--------------------------
Here's a wholesome palette cleanser story:
Patches stares out the window, thinking about the life he once lived. Is it much different from what it is now? Still inside, just looking outside and observing the world.

The memory of everything lost and everything learned through it. Looking around, could it ever be denied that he's tried to make a difference? At what point will people finally accept that and stop defining him by the way he once was? Can a lost reputation ever truly be recovered?

Pressing his paw against the cold window pane, a tear escapes his eye, as he so ardently begs for forgiveness from the world before him.

He looks away from the window and settles down into a chair...it's too hard to think...the memory Angel sitting in a chair facing across from him, sipping away at their favorite tea. What drove such inexplicable behavoir, when everything was so perfect? Looking to the side as Angel usually does, Patches now cries at the true cost of the actions of yesteryear. It's cruel that things can be relived but are locked away behind time, so that can never be regained.

Olive hears the whimpering and peaks out their door to see Patches covering his eyes and crying. It's a hard sight to behold, because the world still won't accept someone who's genuinely tried. Olive silently makes their way to the chair opposite to Patches and silently sits in it.

After a few minutes, Patches looks up and sees Olive in the chair. He says nothing and just turns his head, away from Olive. "What do you want..." he asks.

"Just for you to be happy one day" Olive says.

"You know what I deserve; let me have it already" Patches whispers.

"Why? You know you can't take it anyways. No, you don't deserve this, what you do deserve is a second chance" Olive says, as they are overwhelmed with love and tears swell in their eyes.

"Patches...I think you should at least give therapy a thought" Olive says. Chocking on their words now, "I...I...just want you to be happy. sniff"
