One dark night in Ponyville, all of the lights of the houses and buildings were turned off for the night, except for one house in particular. In one of the fairly large house's rooms, a young man with dark blue hair with white highlights, ice blue eyes, and wearing a white lab coat over a blue outfit was working on writing down what he had done for his research thus far, the powder blue wings on his back furling and unfurling every so often. After a while, he stopped writing and looked over the notes he wrote down.
"That should do it for today," he muttered to himself before hearing a knock on the front door.
He set down his notes and got up from his work desk, walking over to the door when he did. He opened it to reveal a woman about his age with pale blue hair with cerulean stripe, dark grey-purple eyes, and wearing a blue outfit underneath a purple star-patterned cape as well as a hat matching the cape on her head, though it was tipped back a bit, exposing an azure horn. The man had noticed the amount of blood on the clothes as the woman looked at him pathetically.
"I'm in trouble, Snowy," she had said.
The man was surprised, but he stepped aside.
"Come on in," he said as the woman went in.
Soon, both people were sitting at a table, with the woman in a set of clothes that were fairly too big for her.
"I wasn't expecting you to let me in like that," the woman remarked.
"I almost thought of turning you away," the man said as he got them some tea, "but then you called me 'Snowy'. You've never done that, not since we were kids. You would just call me by my actual name, Snow Flight."
The woman softly smiled.
"Guess I should've known my own cousin would be too smart for his own good," she remarked.
"You may have been a giant pain in the neck," Snow Flight started, "but you're still family, Trixie."
"That's true," Trixie said.
"Now, tell me why you showed up, looking like a blood fest," Snow Flight said.
Trixie had sighed.
"I... I've been killing people, Snowy," Trixie said.
Snow Flight became surprised at that.
"... How long?" he asked.
"It's been happening for weeks," Trixie answered. "I just don't know what's wrong with me. I had gotten back from practicing my act in the Everfree Forest and then the thoughts started. All I kept thinking about every day was killing and doing other ghastly things. Then, one day, the urges got too strong, so I set up a place called "Trixie's Fun House" and I started..."
"You started what?" Snow Flight said gently.
"... I started raping and killing people. I've even started a hitman business of all things."
Snow Flight was shocked at that.
"Why did you come to me, then? If you get caught, I could get in trouble for aiding and abetting a criminal."
"Because if there's anyone who can help me, it's you. You could find out what's wrong with me."
Snow Flight thought for a bit before sighing.
"Okay, I'll help. But you have to promise me that you either turn yourself in or go into hiding in case the Royal Guard suspects something."
"May I never perform again if I don't," Trixie promised.
"All right," Snow Flight said. "I'll go get a room ready for you. We start first thing in the morning."
"Okay," Trixie said.
Snow Flight then went to get a room ready for Trixie to stay in for the time being. As he did so, he picked up a phone and dialed a number, waiting a bit.
"Hello?" he heard a tired female voice say.
"Hey, Golden Harvest, it's me," Snow Flight said.
"Snow Flight?" Golden Harvest asked, confused. "You should be in bed by now, what's going on?"
"Think you can come over to my house tomorrow?" Snow Flight asked. "I promise I'll explain everything to you."
"Okay, I'll be there," Golden Harvest said. "But you owe me if I had to miss breakfast."
"Fair enough," Snow Flight said before the two exchanged good-byes and hung up.
He soon got a room set up and went to get Trixie. After getting her situated, he went to bed himself. When morning came, Snow Flight's alarm went off, which he shut off before getting up. He got dressed for the day ahead and was about to get everything in his lab ready when he heard a knock on his door. He walked over and answered it, seeing a woman with carrot orange hair, green eyes, and wearing a pale yellow shirt with matching skirt and shoes as well as holding a box.
"Derpy made too many muffins for breakfast," the woman said. "So, I brought extra for the both of us."
"That's good, Golden Harvest," Snow Flight said as he led Golden Harvest inside. "I need to set up in the lab, so I'll tell you everything there."
"Okay," Golden Harvest said as she followed Snow Flight to the lab.
As Snow Flight got everything ready, he explained to Golden Harvest what Trixie had told him last night.
"Wait, you mean to tell me that she's behind some of the disappearances?!" Golden Harvest asked in surprise.
"Yeah," Snow Flight said. "And in case you ask, she only went to me so that I could find out what's wrong with her."
"You could get in trouble if she gets caught," Golden Harvest said.
"I know," Snow Flight said. "But I'm willing to take that risk if it means that my own cousin would be back to her normal self once I help her out."
"Then why did you call me over?"
"Mostly because I needed someone to confide in about what I'm about to do. That and I'm gonna need an extra set of hands with some of the experiments."
"Makes sense," Golden Harvest admits.
"Yeah," Snow Flight said before looking at the clock. "I'm gonna go get Trixie."
"Is there anything I can do while you're at it?"
"Yeah, there's some spare lab coats in that closet," Snow Flight said as he pointed to the closet. "You can get one from there."
"All right," Golden Harvest said as Snow Flight went to the bedrooms.
He then walked over to the room Trixie was in and opened the door to see Trixie sitting on the bed.
"Hey," he said. "You ready?"
"Ready as I'll ever be," Trixie said as she got up from the bed.
Snow Flight only nodded as he led Trixie to the lab, where Golden Harvest was dressed in a lab coat and holding a clipboard.
"Don't worry, she's here to help too," Snow Flight said to Trixie, who only nodded in understanding.
Snow Flight then led Trixie over to an examination table and helped her onto it. He then, after he and Golden Harvest put on gloves, started by checking Trixie's vitals with Golden Harvest helping him by giving him the needed tools. Once he took note of the vitals, he then took out a syringe and checked to see if it was sterile.
"Think you can disinfect Trixie's arm?" he asked Golden Harvest before pointing. "There's some rubbing alcohol in that cabinet."
"Okay," Golden Harvest said as she went and got the items.
Snow Flight then got ready as Golden Harvest disinfected Trixie's arm.
"Don't worry, I just need a sample of your blood," he said to his cousin.
"Okay," Trixie said.
Snow Flight nodded and stuck the needle into the disinfected spot, drawing out a bit of blood before pulling it out. Golden Harvest got a Band-Aid out and placed it on the spot where he got the blood from as Snow Flight took the sample to a centrifuge. He placed the needle into a vial and squirts the blood into the vial. Once that was done, he placed the vial into the centrifuge and activated it. As the centrifuge worked, he went to collect more samples from Trixie, with Golden Harvest helping him. Once that was done and the samples were placed in analysis machines, Snow Flight had written down what Trixie had told him as Golden Harvest placed a muffin in front of him.
"You're gonna be hungry after all this, trust me," she said as she gave a muffin to Trixie.
"I'll just take your word for it," Snow Flight said before frowning. "I'm not sure if anything we got so far would help."
"What do you mean?" Golden Harvest asked.
"Well," he started as he began to eat the muffin, "the whole purpose of experiments is to test something. However, in order to test it, you would need several test subjects in order to see if your theory or hypothesis works. I know that something could be wrong with Trixie, but I only have her as a test subject. I need to have more test subjects to at least think about applying for a research grant."
"So, unless you know of anyone else in a similar situation as Trixie, you're stuck," Golden Harvest said.
"Yeah, pretty much," Snow Flight said as he finished his muffin.
Golden Harvest thought for a bit as Snow Flight resumed writing his notes.
"You know what you need?" she asked. "You need to take a break from all this."
"I appreciate the notion," Snow Flight said, "but I can't just take a break. The machines sometimes tend to act up and that's why I have to supervise them."
"You're going to work yourself to death," Golden Harvest said. "You should take a break."
Snow Flight sighed.
"Okay, I'll take a break," he said. "But only because you're my friend."
Golden Harvest smiled as he said that. Snow Flight soon finished writing his notes and set them aside.
"Trixie, think you can keep an eye on things?" he asked.
"I'll try," Trixie said.
"Okay," Snow Flight said as Golden Harvest took off the lab coat and neatly laid it down.
Both Snow Flight and Golden Harvest then left the house and started walking around Ponyville.
"So, how's Derpy been?" Snow Flight asked as they walked.
"She's been fine ever since she started dating Time Turner," Golden Harvest answered.
"That's good. Dinky and Amethyst Star could use a father in their lives."
"You know, I told Derpy the exact same thing."
Snow Flight chuckled at that. After a while of walking, Snow Flight checked his watch to see that it was about lunchtime.
"Hey, you wanna grab a quick bite to eat?" he asked.
"Sure," Golden Harvest said as the two of them walked over to Sugarcube Corner.
They had walked inside as a woman with hot pink hair streaked with pale pink, pink eyes and wearing a yellow and pink apron over a light blue dress and pink earrings sees them.
"Oh, hello, Golden Harvest, Snow Flight," the woman said in greeting. "What would you like today?"
"Some carrot cake if it's not too much trouble, Mrs. Cake," Golden Harvest said.
"Do you still sell blue velvet cupcakes?" Snow Flight asked.
"Of course," Mrs. Cake said with a smile. "Pinkie made some this morning just for you."
"Okay, then I'll have some blue velvet cupcakes," Snow Flight said with a nod.
Mrs. Cake nodded back and went to get their orders. Golden Harvest went to get her Bits when Snow Flight stopped her.
"Let me," he said. "My treat."
"You're such a gentleman," Golden Harvest said with a smile.
"Least I can do," Snow Flight said.
Mrs. Cake came back with their orders, which Snow Flight paid for with the right amount of Bits he had on hand. The both of them walked over to a nearby table and sat down.
"Hey, have you noticed that Mrs. Cake seemed out of it?" Snow Flight asked as he started taking off the first cupcake's wrapper.
"She's probably stressed out," Golden Harvest stated as she started eating her cake. "Being a co-owner of a bakery and mother of twins can do that to some people."
"True," Snow Flight said as he took a bite.
He then made a face.
"What?" Golden Harvest asked.
"Something's wrong with this cupcake," Snow Flight answered.
"What do you mean?"
"Don't know. It tastes funny."
"Maybe Pinkie put in the wrong ingredients."
"Doubtful. She's been more careful about what she puts in her baked goods after the Baked Bads Incident."
"Ugh, I know. I couldn't even look at a muffin without getting sick for a whole week."
Snow Flight took a look at the cupcake as a young woman with pink poofy hair, blue eyes, and wearing a pale pink outfit walked up to them.
"Hiya, guys!" the woman said with a bright smile. "How are the baked goodies today?"
"Delicious as always, Pinkie Pie," Golden Harvest said.
Snow Flight nodded in agreement.
"Okie-dokie-lokie!" Pinkie said as she walked back to the counter.
"That was close," Snow Flight said once Pinkie was out of earshot.
"You didn't want to tell her about the cupcakes?" Golden Harvest asked.
"No. She'll probably think I don't like her cupcakes. Plus, I don't like complaining about funny tastes if it's just the taste that's the problem."
He then looked at the cupcake once more.
"I have a theory," he said as he took out a scalpel and a pair of tweezers from his pocket and checked both items for cleanliness.
"What are you going to do with-?" Golden Harvest said before he used the scalpel to cut into the cupcake. "... Those?"
"There's a method to my madness," Snow Flight only said as he found something while cutting into the cupcake.
He then made a hole big enough for removing the item and used the tweezers to get it out. After a bit, he got the foreign object out, revealing it to be a human finger covered in cupcake bits. He became surprised as Golden Harvest let out a scream at the sight. Snow Flight looked towards the counter to see Mrs. Cake and Pinkie standing there, staring back at him. He then noticed that Pinkie had a crazy look on her face as she took out a knife.
"Mrs. Cake, look out!" Snow Flight suddenly shouted before Pinkie suddenly stabbed Mrs. Cake in the neck.
Mrs. Cake fell to the floor as Pinkie suddenly bolted out of the bakery. Snow Flight ran over to the counter.
"Golden Harvest, you go get Nurse Redheart!" he shouted. "I'll try and save Mrs. Cake!"
"Right!" Golden Harvest said as she ran out of the bakery.
Snow Flight had gotten behind the counter and knelt down next to Mrs. Cake, who was gasping for air as she held her hand over the wound.
"Don't worry, help's on the way," he said as he put on medical gloves. "I just need you to hold on for a little bit longer, okay?"
Mrs. Cake only nodded in response as Snow Flight helped her apply pressure to the injury. After a while, he heard the door open.
"Over here!" he shouted as he looked over to see that Golden Harvest had entered with a light pink-haired blue-eyed woman wearing a white nurse's outfit in tow.
Both women rushed over to the counter, with the woman in the nurse's outfit joining Snow Flight behind the counter.
"I came as soon as I heard," she said as she looked over the situation.
"Thanks, Nurse Redheart," Snow Flight said.
Nurse Redheart nodded in response as she slightly moved both Snow Flight and Mrs. Cake's hands.
"Good thing you acted quick when you did," she said as she started fixing up the wound. "A second or so late, she would've bled to death."
Snow Flight sighed out of relief.
"However, I'm going to have to take her down to the hospital so that we can at least monitor her vitals," Nurse Redheart said.
"Wouldn't you need to notify Mr. Cake about that?" Snow Flight asked.
"About that," Golden Harvest started, "he happened to be there with their babies when I told Nurse Redheart what happened."
"Damn it," Snow Flight muttered. "That means that he'll alert the authorities."
"Based on what I heard, it'll be a good thing he would," Nurse Redheart said. "That way, some of the disappearances can be cleared up."
"True," Snow Flight said with a nod.
Nurse Redheart nodded. Eventually, the Royal Guards had arrived, with Nurse Redheart and other paramedics leading Mrs. Cake, who was laying on a stretcher, towards an ambulance. Both Golden Harvest and Snow Flight had told the Royal Guards what had happened as well as answered any questions they had been asked. Once that was done, the two were clear to leave and they started walking home.
"Well, that was... unexpected," Golden Harvest said.
"Yeah," Snow Flight said before thinking.
"What is it?" Golden Harvest asked as she noticed.
"I think that there's something wrong with Pinkie Pie."
"What do you mean?"
"Think about it: she somehow killed and made people into cupcakes for no apparent reason."
"That's true," Golden Harvest said as Snow Flight realized something.
"What if Pinkie is in a similar situation as Trixie?" he asked.
Golden Harvest stared at him in surprise.
"Come on!" Snow Flight said as he grabbed Golden Harvest by the hand and started running towards his house.
"Hey, slow down!" Golden Harvest shouted as they ran.
After a while, they soon reached his house and hastily entered. Snow Flight let go of Golden Harvest's hand and ran into his lab. He looked at the analysis machines and centrifuge as Golden Harvest entered.
"Snow Flight, you're scaring me," she said.
"Sorry, but I know that something's up with both Trixie and Pinkie Pie," Snow Flight said as he looked at the vial of Trixie's blood. "Wait a minute... Hey, get over here."
Golden Harvest walked over as Snow Flight showed her the vial. She saw that some of the red blood cells have black spots on them.
"Oh, my..." Golden said as shock appeared on her face.
"That's right, some of Trixie's red blood cells are diseased," Snow Flight said. "But every Equestrian's body has white blood cells, which helps take care of viruses and other foreign agents. So, why didn't Trixie's white blood cells do something about that?"
"Maybe you could consult someone?" Golden Harvest suggested.
"Who, though? Time Turner specializes in time-based science and Twilight Sparkle probably has a lot on her plate with her duties as a Princess."
"Well, you never know."
"True," Snow Flight said before making a face. "I haven't seen Trixie since we came back from the Sugarcube Corner."
"Maybe she went to bed," Golden Harvest said.
"Maybe. I'll go check."
Snow Flight then walked up to the room he was letting Trixie in and entered, noting that there were the same clothes he made Trixie change into neatly folded onto the bed along with a note. He picked up the note and read it.
Thank you for letting me stay with you, even if my time at your house was short. It's just that I can't stay here for any longer than I needed to. I saw the Royal Guards from the window, but they didn't see me. I told myself that it was probably just either a patrol or that they were after someone else, but I got paranoid. I couldn't take chances, so I decided to run away or turn myself in, whichever comes first. Just in case, I changed back into the bloody clothes so that you wouldn't get charged for aiding and abetting a criminal. I really hope you can find out what's wrong with me and fix it.
Snow Flight blinked and then folded up the letter.
"It's not just you I may have to cure," he said as he walked out of the room. "It's you, Pinkie Pie, and who knows who else out there has the same signs."
He then closed the door and went to go find Golden Harvest.
