Stormflower, Sunkick, Joan, and Scootaloo woke up early the following morning to catch the first train out of town. The four ponies waited silently at the train station as a cool morning breeze swept through the town. Twilight met up with them at the station to see them off.

"So where exactly are the four of you off to?" she asked.

"The rock farms," Joan replied.

"The rock farms? What's there?"

"Answers," Stormflower replied.

"Could you be a little bit more specific?"

"It's a long story but I feel that a certain tragedy that took place ten years ago at the rock farms has something to do with Rainbow Dash's murder."

"So you all have decided to form your own investigation team?"

"Yep!" replied Scootaloo happily.

"Well. Be careful. If there is a connection between Rainbow Dash's murder and this tragedy then the killer could be waiting for you at the rock farms."

"We know the risks," said Joan.

"And we're all willing to take them," Stormflower continued. "I...we just want to find the truth."

"I understand," said Twilight soothingly. "I do too."

A train whistle echoed off in the distance and Stormflower, Sunkick, Joan, and Scootaloo prepared to leave.

"Well here it comes," said Joan happily.

"We'll be back in a few days at max," Stormflower said as she turned to Twilight.

"Be careful...and good luck," said Twilight.

A few moments later, the train pulled into the station and Scootaloo quickly ran into the nearest train car. Stormflower and Joan smiled at each other and followed the excited filly into the train. Sunkick hesitated for a moment and turned back to Twilight. He took in a large breath of air and stared the lavender unicorn straight in the eye.

"You've seen her, haven't you?" he asked. Twilight's eyes widened slightly and she sighed. "You've made contact with my sister. I can smell her on you."

"Y...yes," Twilight replied. "I...I saw her yesterday. She temporarily took over Applejack's body."

"Twilight...why can I sense her?"

"Huh?"

"How come I can sense Dash's spirit? How come I can talk to her when she's here with us?"

"I guess...I guess you have a sixth sense."

"A sixth sense?"

"Yeah. Something that allows you to make contact with the deceased."

"But why has it suddenly appeared now? How come I suddenly have this ability?"

"Maybe you've always had this ability. You just never had the need to use it until now."

Sunkick sighed and smiled. Scootaloo leaned out of one of the windows of the train car and banged her hoof on the side.

"Come on, Sunkick! The train's leaving in like two minutes!" she snapped. Twilight and Sunkick laughed. Twilight then approached the yellow pegasus and hugged him.

"Be careful, okay?" she whispered.

"I will," he replied. Sunkick turned towards the train and began to enter the train car when he turned back to face Twilight one last time. "What did she say? What did Dashie say to you when you saw her?"

"She...she said that she didn't want to go."

Sunkick sighed again, turned away from Twilight, and walked into the train car. He found a seat next to Scootaloo and looked out the window as the train slowly began to depart from Ponyville Station.

"Goodbye!" Twilight called as she waved her right hoof in the air. Stormflower stuck her head out of her window and waved goodbye along with Joan. The train eventually became nothing more than a speck off in the distance and it was at this point that Twilight finally left the station. She walked silently for a few seconds until she bumped into somepony. "I'm sorry! I wasn't looking and...oh hey Pinkie Pie!"

Pinkie Pie looked at Twilight with a huge grin plastered on her face. Irena was standing next to her.

"Morning Twilight!" said Pinkie joyfully. "Where are you off to?"

"I'm heading back to the library. I need to discuss a few things with Aaron."

"He's still in town? I thought that he would have left after they discovered Dashie."

Twilight stared at Pinkie awkwardly. Something was off about the pink earth pony...but she couldn't pinpoint what it was exactly.

"Yeah...he's still in town. He, Applejack, and I are looking into Rainbow Dash's murder," Twilight continued. "We're going to find the pony who did this and make sure that they get what they deserve."

"Well we wish you the best of luck in your investigation, Twilight," said Irena.

"Yeah!" Pinkie said with an overly-happy smile. "Best of luck!"

"Thanks," said Twilight.

"Say, Twilight. I saw you coming from the train station. Did somepony leave town?"

"Yeah. Stormflower, Sunkick, Joan, and Scootaloo just took the morning train out of town. They'll be back in a few days so don't worry."

"Where exactly are they headed?"

"Stormflower said that they were going to the rock farms to look into some tragedy that happened ten years ago."

Pinkie and Irena instantly fell silent and lowered their heads.

"I guess I can't blame them for being curious," said Irena.

"Do you two know about this tragedy?" Twilight asked.

"Yeah. The tragedy she mentioned involved our family."

"What happened?"

"Our sister was-"

"She died," Pinkie said suddenly. Twilight turned to Pinkie as her eyes widened.

"You...you had another sister?" Twilight asked.

"Bellamina. She was one year younger than I was. She was six when she died."

"How did she die, if you don't mind me asking?"

"She just died. I don't really remember how."

Something was off. Twilight knew it. Pinkie was hiding something.

"Excuse me," Pinkie continued. "But I have some chores to do at Sugar Cube Corner so I'll see you two later!"

The pink pony smiled sadly and raced off in the direction of Sugar Cube Corner. Irena sighed and turned towards Twilight.

"Pinkie doesn't remember how Bellamina died because she witnessed her death," she said.

"What?" breathed a stunned Twilight.

"Bellamina was murdered and Pinkie witnessed it. I was never told the details of the murder but I know that it was incredibly...graphic."

"I can understand why Pinkie must have blocked it all out. It must have been an incredibly frightening event."

"Yeah. I remember when I first saw her after the murder. Her eyes were wide, her hair was straight, her mane was dirty, and she hardly spoke. She was in a shock-like state for several weeks. We took her to the hospital where doctors and nurses cared for her 24/7. Then, one day, she just returned to normal."

"Just like that?"

"Yeah. It was the strangest thing. One second she was silent and grim and the next second she was happy, vibrant, and ready to throw another party. She seemed to have forgotten about Bellamina's death altogether. My parents told her that Bellamina died but they never told her how. They told me to never tell Pinkie the truth behind Bellamina's death. I think they just thought that Pinkie would be better off not knowing the truth."

"That makes sense. Have you ever...tried to tell her?"

"Sometimes, but I'm never able to. Either I don't have the will to do so or she interrupts me and changes the subject. She really doesn't like talking about Bellamina or what she went through a decade ago. I think she remembers bits and pieces of her time in the hospital but that's about it. The death of Bellamina, the investigation, and most of her time in the hospital were just wiped from her memory in one fell swoop."

"Honestly, I think that's for the best."

"Yeah. I guess it is."

Meanwhile, Pinkie ran up to her bedroom in Sugar Cube Corner and locked the door. She shut the windows and sat on the edge of her bed. For several minutes, she sat there with a grim look on her face. Then she began to cry.

"Stop it!" she snapped. "You're making me cry!"

"I can't! I miss her too much! I miss them all too much!" cried the voice.

"Stop it! Stop it! Stop it! STOP IT!"

Pinkie fell back on her bed and curled into a ball. Tears strolled profusely down her face and soaked their way into the sheets of her bed.

The uncontrollable sobbing eventually came to a halt and Pinkie slowly calmed herself down. This was bad. She was losing control. Everything was falling out of place. The noose was tightening around her neck with every passing second. There were too many variables working against her. Rainbow Dash's family, the investigator, everypony else in town, the weak spirit within her, and possible forces from beyond the line of life and death. She reached under her bed and pulled out a small box. She opened the box and pulled out a silver switchblade. She cradled it in her hooves and opened it. She grabbed it with her mouth and swung it about for a couple seconds. She chuckled sadistically as she took the switchblade and put it back in the box. The familiar urge was coming back. It had been far too long since she had had her last play date. The time was close.

"Please stop!" the voice within her begged. "Please stop this madness! Just...just stop!"

"No," Pinkie whispered happily. "I will never stop. They will never catch me. I'll kill them all. Stormflower, Mr. Crop, Twilight Sparkle, Applejack, Sunkick, and all the rest! I'll kill them all! I'll have my fun with them! The time is close dear little Pinkie Pie! Pinkamena has a few get-togethers to prepare for!"
