After receiving a call, the downpour occurred in the Ponyville. Two police cars and one ambulance were driving through the street soaked in a rain. Three pegasi officers donned in a raincoats were also flying above the car.

"Oh, buck sake. This downpour-" said Officer Storm as he wiped out some droplets that got into his eyes."is making me can't see anything beyond 400 meters!"

"Well, at least it's not a storm" said male pegasus officer as he smirked.

"I hate your joke when it includes my name." replied Storm in a serious manner as they continue to head toward Rainbow Dash's residence.

30 MINUTES LATER

The pegasi officers landed as two police cars parked in front of the house, the female unicorn officer, Officer Denvy got out of the car along with other officers. "Alright, we know how we do this, right?" asked Denvy.

"Yes, Den. You ready for this Dot?" replied and asked Storm as he positioned himself at the doorway.

"As always" answered Dot as they breached the door, Storm aims his gun into the dimly lit house as Peridot saw a shadowy figure upstairs.

"I will check upstairs, both of you check downstairs. Got it?" said and asked Storm.

"Roger that!" replied Peridot and Denvy.

As the command had been given to the rest of the officers, Storm and one earth pony officers rushed upstairs. As soon as they reached upstairs, they heard someone's weeping coming from Dash's bedroom.

"Oh, that hardly explains why someone called us." said the earth pony officer.

The officer kicked the door opened, only to found Lightning Dust sobbing about her nightmarish experience. Beside her was Rainbow Dash sitting on the floor. Both of their wings were wounded.

5 MINUTES LATER

After minutes of investigation, they got two strange devices for evidence, one of them was the one that Lightning Dust was strapped in and died in, it was a metallic pole with multiple small blades attached to the small joints protruding from the sides of the poles and they saw three circular saw blades that was placed few inches away from where the victim are strapped, the saw blades will be few inches away from their back and the mechanism made it able to push itself toward the victim.

"I wonder who's able to construct these strange contraptions." asked Denvy as she inspected the device.

"You asked this in every crime scenes, Den. It can be any kind of pony.....the one which is really smart." replied Storm as he slowly pace around the room. "You found anything, Storm?"

"Nope, like always." answered Storm as he used the handheld scanner to search for magic traces. "Yeah, nothing." said Storm as he turned off the scanner.

After a while, the officers walked downstairs and they saw Frank, their fellow earth pony officer who just finished escorted Dash and Dust to the ambulance outside, the sirens were blaring along the red lights from it, the downpour were almost stopped, he turned his head around and said "You all got anything?". His answer was followed by the three officers shaking their heads.

"So, what did they say?" asked Denvy.

"Well, I got both the tape and Dash's story about what was happening here. They went to the hospital to fix and stitch up their wings." replied Frank "We'll talk about it at the department."

After the officers were back from their duty, the officers sat down on the chairs in the office.

"Go ahead, Frank. We're listening." said Storm.

"Alright, so, we found this tape in the bedroom, right? And we'll call the killer "Jigsaw", because every time the victim died, he'll cut their flesh into a jigsaw shape." said Frank

"So, what did Dash say?" asked Peridot.

"So, she said..." replied Frank as he began to tell what did she say.

FLASHBACK

After returning home from the Wonderbolts Academy. The downpour occurred suddenly all over Ponyville, soaking the entire town with rain.

"Do you have a raincoat?" asked Lightning Dust

"Umm...Rarity borrowed it yesterday and still not returning it to me, so ,no." replied Rainbow Dash

"Guess I have to stay here." said Dust "Until the rain stops."

"Hey, I gotta sleep." said Dash as she stretched "I'm so tired today."

After a while, Dust heard Dash's scream from upstairs. "RAINBOW" said Dust as she ran upstairs. When she opened the door, she saw Dash tied to the strange contraption. "What?" asked Dust. Suddenly, a figure wearing a pig mask leaped out of a wardrobe and jabbed a syringe into her neck.

After the drug effect was gone, Dust found herself strapped to the exact same device that Dash was strapped to. She felt terrible pain from her wings as she looked behind her, her wings were stabbed by various small blades that connected to the contraption. She was shocked and she also saw that she was also handcuffed to the back of the device. The audio tape hanging from the ceiling played once they woke up.

"Hello, Rainbow Dash. And Lightning Dust. I want to play a game. Both of you, for years you are taking yourself to be prideful. A pride for being the greatest flyer in Wonderbolts. I know that it's your goal, but you put too much of yourself into it. Today, the pride the one that is causing you a harm tonight. In 70 seconds, Rainbow must free herself from the device by injuring the tool that she use for her pride: your wings. The only way to survive is to pull yourself of the machine, therefore, this will make your wings heavily wounded, but you'll survive. After you free yourself, you must unlock the handcuff that hold Dust to the machine. If you failed to pull yourself out or free Dust, the saw blades at the back of the device, attached to the machine will engage, shredding your back and your wings. Your time is running out. Live or die, make your choice."

"70...69...68" the timer was counting down, Dust was terrified.

"What are we gonna do?" asked Dust.

"Umm......follow what did the guy just say?" replied Dash "If this is the only way out.....oh no."

"61...60...59" as the timer counting down, Dash begins to pull herself out of the machine painfully. "Come on, Dash! You can do it." cheered Dust as Dash temporarily stopped due to severe pain from her wings.

"50...49...48" Dash successfully pull herself out, the blood from her wings were dripping. She slowly walked toward Dust due to her injury. She searched around the device for a key.

"39...38...37" After searching, she found it, tied to the pole. She, then, uncuffed Dust. But, however, she realized something.
"Dust?...uh..you must pull yourself out too." this line completely shocked Dust. "Come on, we don't have time." said Dash as she grabbed Dust's waist and started pulling her out. Dust grinded her teeth hard from the pain.

"25...24..23" as the time was running out, Dust made a hard push, almost freeing her from the machine. "Dust, just one more and you'll free." said Dash as she pull Dust's waist hard. But it looked like Dust stopped for a moment, because of her bleeding wings.

"10...9...8" as the timer almost hit zero, Dash pulled Dust hard, freeing Dust from the contraption. Just few seconds before the saw blades engaged.

"Are you alright" asked Dash as Dust lay on the floor.

"Yes." answered Dust as Dash went downstairs to grab the towels to hold their bleeding wings and called the police.

FLASHBACK ENDED

As soon as Frank finished talking, Denvy was the first one to speak up. "Jigsaw tested them, because they're prideful?"

"When it's not a problem to us. It's problem for him." replied Frank "That's how Jigsaw works."

"I can't stand seeing the ponies dying like this. We must arrest this killer. We must do it fast." said Storm.

"You look tired, Storm" said Peridot. "I suggest that, you go take a nap at your house. We'll handle this."

"Alright, Dot." said Storm as he smiled "I trust you." after he finished his sentence, he left the room and the department, heading to his home.
