All of Rarity's friend know that she got stabbed, but what they don't know is that a pony had actually been murdered. Who was it? Surely Pinkie would have noticed by now if somepony had gone missing.
That's when it hits Pinkie. Where is Derpy? Pinkie Pie is good friends with Derpy. Derpy wouldn't just leave. Maybe something came up and she had to go visit her relatives. Yeah, that sounds plausible.
It is pet day, the day that the mane six bring their pets to hang out together. Even Rarity came, because it didn't take much time for her to recuperate from her stab wound. If Gummy had teeth, this probably wouldn't be such a fun day. How does an alligator not have teeth? I suspect Pinkie has something to do with it. She isn't as innocent as you might think. Maybe it's something like getting a cat's claws capped?
"Hey Twi, do ya notice sumthin' odd?" ask AJ.
"Now that you mention it, yes. Where's Fluttershy?" she responds.
All of them sit at there and think about that for a minute. Fluttershy would never miss pet day. She was the pony who suggested it in the first place. They have to go to check up on her, to make sure she didn't get hurt like Rarity did.
When they get to her house, Pinkie Pie is the first one in line, so she knocks on the door. "Is anypony home in there?"
No answer.
Rainbow Dash breaks down the door, because it is locked. That's no excuse though, now RD will have to pay for the replacement.
"Eep!" cries a high-pitched voice.
"Fluttershy, we know you're in there somewhere. Can you come out and tell us what's wrong?" Twilight asks.
"Darling, please come out of there," Rarity adds. "We're worried for you!"
Fluttershy sighs like she has been holding her breath for five minutes. "Oh, it just you guys. I was locked up i... he...." The rest of the sentence is unintelligible.
"Speak up, Flutter, we can't here you!" yells RD.
"Oh sorry. I guess it's ok if I come out now because you guys are here. Give me one little second, if you don't mind."
The ponies can hear locks of all kinds unlocking and turning from the other side of the door. It must have taken a lot of effort on her part to install all of those locks. The door opens slowly, and Fluttershy looks around carefully.
"Well, you see, I was hiding from the ... um the ..."
"Spit it out." Rainbow Dash rolls her eyes.
"THE MURDERER!" Fluttershy screams, when she gains the courage to do so.
The ponies all gasp. Their eyes are all wide open in astonishment. Even tough Rainbow Dash is scared silly from hearing this.
After a short silence, Twilight speaks up first. "Fluttershy, do you mean to tell us that somepony was killed in Ponyville? Surely we would have all heard about this before, right girls?"
The other ponies nod their heads vigorously, looking desperate for some kind of answer.
"Well, that's just what I heard. And I know for sure that it's not a rumor. And I'm also pretty sure that is is the same pony who stabbed Rarity."
Pinkie Pie says, "I have been getting these new weird Pinkie sensations. It's kind of a creepy crawly feeling. I guess that has something to do with the murderer, don't you think?"
When Pinkie Pie's Pinkie Senses tell her something, it's 100% certain. Fluttershy couldn't have just heard a rumor. Pinkie Pie said she felt new sensations, and Pinkie always knows what her senses are telling her! It can't be just a coincidence.
"Oh, Fluttershy," AJ says, "I reckon Twi and Pinkie's gonna find the stallion who did this. Don't you go worrying now, it's gonna be fine. So can you please bring Angel and come to pet day with us? Pretty please?"
"Well, okay. I really don't want to miss out on the fun. Thank you for coming and checking on me. It's not the murderer is going to strike in the middle of the day anyhow. Sorry for worrying you girls."
"It's okay, Flutters," says RD, "I'm going to show that stallion who's boss!"
Fluttershy picks up Angel, and the ponies go to their pet day gathering spot. The sky was clear before they left, but it is now starting to get cloudy. Maybe the pegasi have a last minute storm planned for today, though usually the pegasi are very organized. After a few hours together, the ponies go their separate ways and back to their homes. None of them are going to worry about the criminal any longer. That would just waste precious energy needed to find and apprehend the criminal.
When Twilight reaches her house, she asks Spike, "Did you hear anything about the murderer?"
"No," says Spike, his eyes drifting off towards the floor.
Twilight notices his eyes drifting, so she asks, "What's up, Spike? Is the news of the murderer bothering you?"
"Yeah, kinda." Spike blushes. He is so cute when he does that. That little munchkin.
"You can sleep in my bed tonight if it would make you feel safer."
"Thanks, Twi. So, are you and Pinkie going to meet up together again tomorrow?"
"Yeah, you can come too. I might need your assistance."
Spike nods, then heads toward Twilight's bedroom. Twilight decides to stay up and study a little before going to bed. She picks up a book called "Spells for Crime Solving". Yes, Twilight has a book for that. No, there isn't an app for that.
At the hospital, Doctor Song is doing her rounds, checking up on patients, dealing with the occasional mishap in the ER, and the like. The murder is on her mind all the while. But there is nothing she can do about it anyhow. All she can do is hope and pray to Celestia that she isn't next. Still, she feels that it is her responsibility to stop the killer in his tracks. There is barely any evidence. Wait, what about the blood stain on the carpet? Perhaps there was something left there. She can't help but wondering why there isn't a big scene going on about the crime. Ponyville seems too calm.
Nurse Redheart smiles sweetly at Song. "Hello, sweetie. Are you still worried about that thing I told you?"
Reluctantly, Song sighs and nods. "Well, yes. I am quite worried. It just blows my mind that something like that would happen the day before I came here."
"It must be a coincidence. How would he know that there was going to be a new doctor?"
"Now that you mention it, it makes no sense that it would have anything to do with me. What was I thinking, nurse? But I'm glad you told me about it, even though it was bound to make me worry. Oh, would you look at the time. I better get going."
"Remember, I'm here for you any time."
Walking away smiling, Song visualizes the stain on the carpet. Wouldn't there be more blood on the floor than just one large stain? Perhaps the rest was able to be washed out. Maybe the blood all went to one spot, instead of splattering everywhere. For that to happen, the victim had to of either died instantly, or gave up trying to get away. Maybe the victim was bagged up to avoid any mess. Song is used to seeing blood, of course, but seeing it soaked into the carpet is much different. Maybe the murder just didn't even matter anymore. The killer might not even be after anyone else, and Song is worried over nothing.
