My Little Diseases (MLP Horror AU)

Miss Cake was laying in her cell, petals falling from her lips and to the floor below as she looked around for anypony nearby. Not that she could communicate to them anyways.

Twilight had injected Miss Cake with a certain disease while passing by her in the streets.
The symptoms began to show rather quickly when Mr Cake found Miss Cake walking through ponyville, with a few flowers growing from her ears.
Twilight raised an eyebrow, she wasnt expecting the affects to start so soon, but then remembered that Miss and Mr Cake’s relationship had started getting very one-sided recently. Mr Cake’s love had become very bitter and lacking, to the point that Mr Cake was leaving the bakery early, leaving Miss cake to close up shop and take care of the twins. Mr cake would then walk around ponyville and could be seen talking with some other mares, these mares were younger than Miss cake and seemed to tick all the boxes for Mr Cake...

Miss Cake still loved Mr Cake with all her heart, as well as their children. But sadly, Mr Cake seemed to be losing feelings, or had just decided to abandon the relationship all together without saying a word.

Now Miss Cake lay in the holding cell of the castle's basement, where Twilight was running tests, when Pinkie Pie walked in. Or what used to be Pinkie.

“So… What's going on with Miss Cake?” Pinkie spoke up, lowering the mask from her face.
Twilight was busy scribbling away on a clipboard, taking down notes of her findings, before telling Pinkie what she had learned about her new disease.

“She has what is called The Hanahaki Disease… It is a disease i made, as per usual... Apparently it occurs when somepony is experiencing one sided love. This causes them to cough up flower petals. As well as cause fully blossomed flowers to grow out of any opening in the body, including the mouth, ears, nostrils and sometimes even eye sockets. It comes to an end when the beloved returns their feelings… This needs to be romantic love only, deep friendship is insufficient… Otherwise the disease will come to an end when the victim passes away from choking on the flowers”
Twilight explained this, looking at Miss Cake as she laid on the floor of her cell, tears filling the baker's eyes as she avoided looking at the 2 ponies.
Twilight continued to explain what the disease was.

”I had injected Miss Cake with this disease a while ago. If their relationship was stable and continued to last as it did a while ago, then nothing would have happened, and Miss Cake would have most likely experienced symptoms, similar to that of the common cold, since her immune system could have easily fought off the dormant bacteria... Normally, the flowers that grow are their partner's favorite flowers. For Miss Cake’s case, the flowers are forget-me-not's. The flowers can be healed by surgical removal, but once the infection is gone, so do the victim’s romantic feelings about their relationship… It's pretty risky, but if Miss Cake gives us her consent, then we could cure her right now. Since it is currently getting rather close to its fatal stages.”
Twilight finished her explanation with a sigh, looking at her notes, skimming them to make sure she hadn't missed anything.

"I may have abandoned my duties as 'princess of friendship'... But i know what Mr Cake is doing, is wrong. Very wrong... So we'll be having him pay us a visit at some point, so be excited for that Pinkie." She then turned to Miss Cake, who was rather worried about forgetting everyone if the flowers were removed via surgery. So she kneeled down and locked eyes with Miss cake, her tone sincere and somewhat comforting.

"Dont worry, when we remove the flowers, the memories of Pound and Pumpkin Cake will remain, since that isn't romantic love, that's family. She wont forget them."

Twilight explained this as her crazed, wandering eyes broke eye contact, and began to shoot around the room to the different cells, seeming to never be able to settle on looking at a singular thing.

"Well, Miss cake? What do you say? Shall we get these flowers out of you so you can return to your kids?" Pinkie asked in a sincere tone. They may both be crazed maniacs, but they knew when someone wasnt supposed to go through something, and they're going to right this wrong.

Miss Cake nodded and stood up, Twilight opened the cell door and the 3 of them made their way further into the basement where there was a surgery room, all sanitized and professional looking. Like it had been taken straight out of a hospital.

Around 2 days later, Miss Cake came wandering out of Twilight's castle, flower free with a big smile on her face. They all exchanged pleasantries before parting ways, where Miss Cake made her way back to the bakery to see her children. All memory of Mr Cake, wiped from her memory.
