Once Twilight And Cadance made it out of the Caves below Canterlot, the detective kinda just drop her off there for the Royal Guards to do the rest and hopefully get her back to The Crystal Empire safetly.

After that Twilight was just completely lost there wasn't anything like graffiti a voice recording tape nothing else to tell her where to go next after a few minutes of wondering around she took a breather in a alleyway before getting attacked by a mysterious hooded pony with button sunglasses and stitched up mouth face mask and injected with a needle knocking her out.

Twilight woke up in what looked like a small cave with small cracks letting sunlight in ''Shit Please don't tell me another FUCKING CAVE!'' the detective said to herself then she put a hoof against the cave's walls causing the entire cave to collapse which revealed the cave wasn't actually a cave it was a pile of books and the sunlight wasn't sunlight coming from the windows but was light come from stagelights

This is when the unicorn detective noticed that there was even more stagelights down the hall, the Golden Oak Library was also a mess, furniture was everywhere either knocked over, broken or destroyed and there was also graffiti on the walls saying Sometimes It's Better Not To Save Them. When she checked the time she was relieved a little since around this time Spike was gone to fetch supplies and would be back in a couple of hours guess. ''Guess The Hacksaw Killer knew about Spike's Schedule and took advantage of it.'' Twilight said to herself

Once getting to the staircase there was a TV sitting on a small table all of a sudden the TV turned on and Stichy appeared on the screen. ''So that's how you want to play it Twilight Sparkle outsmarting my traps in unexpected ways well your next test will put that to the test.'' Stichy said before the TV shut off

Twilight went downstairs using her horn as a light source to find it even more of a mess the windows were boarded shut there was stains of ink on the floor. Almost all the furniture was destroyed, the ones that weren't destroyed were broken with a huge part of them missing. There was also stuff that looked like sticky notes covering the walls and objects that looked like mailboxes sticking out of the ground.

The only source of light downstairs beside the detective's horn was a staticky TV this is what made Twilight realize that a single chair wasn't destroyed or broken when she approached it from behind it turned out there was a pony strapped to the chair wearing button sunglasses and stitched up mouth face mask. Thinking this was the mysterious hooded pony that injected her with a needle, the detective charged up a blast only to get interrupted by staticky TV turning on and Stichy appearing on the screen causing the unicorn tomisfire destroying a piece of broken furniture

''Hello once again Detective Sparkle i wanna play a game the pony you see infront of you is in desprate need of help but it isn't your job to save them Sometimes It's Better Not To Save Them underneath the dollhead mask is a criminal undeserving of the life they were given and those who don't appreciate life don't deserve it sometimes it better not to save them, you either save the victim or walk away the choice is yours.'' Stichy said before the TV cut back to static

Twilight use her magic to take the button sunglasses off the ponie's face and pulled down the stitched up mouth face mask revealing the pony was Photo Finish and she was also gagged. Twilight found a tape on the chair and played it ''Hello once again Photo Finish i wanna play a game, you've raped multiple stallions and mares and taken pictures of your actions.'' The object that looked like mailboxes turned on a revealed they weren't mailboxes they were lights and the sticky notes weren't sticky notes but photos of Photo Finish raping stallions and mares. ''I've turned your camera into a scalping device that once activated will pulled your mane back until it's completely ripped off your head and you'll bleed out live or die make your choice.'' Sitchy explained

The unicorn detective removed the gag from Photo Finish's mouth ''Are you a cop?'' Photo asked sobbing ''Yes i'm a cop i'm a detective.'' Twilight told her using her magic to pulled the stitched up mouth face mask over Photo's face pulling and releasing a metal cord setting off a 1 minute timer. Twilight didn't want to use magic on the Scalping Camera or else it'll make it worse which she learned from The Rack.

''What is that, What did you do? AHHHHHHHHHHHH!'' Photo yelled as the scalping camera started pulled back her mane ''THE CODE IS IN THE GEARS'' Photo yelled sobbing

''The gears right'' Twilight said looking at the gears unfortunately the gears were turning very slowly which wasn't good for saving time. Twilight trotted off ''Where are you going'' said Photo sobbing as her mane started get stretched ''AHHHHH COME BACK''

Twilight trotted over to her self-defense cabinet where she kept all here weapons like knifes and blunt objects in case anypony broke in the Golden Oak Library. In hopes of cutting Photo Finish's mane before she gets scalped but when she used her magic to open it the detective found a note saying. ''Nice Try you're wasting time'' Twilight decided to run back to Photo Finish in the Scalping Camera

''HURRY GET THE CODE!'' Photo yelled as blood started coming out from her scalp. This is when Twilight saw a number on 6 one of the gears ''Got one'' the detective said typing 6 onto the number pad ''HURRY'' Photo said as blood flowed onto her face and into her eyes. Suddenly the gears all showed their number at the same time ''There's the code'' Twilight said typing in the last of the code.

Photo mane was released from The Scalping Camera the straps also came off causing Photo to fall to the floor. Twilight trotted off to grap a rag too wipe the blood off her face but Photo Finish reached into a cabinet and pulled out a knife.

When The unicorn detective came back Photo was gone ''The Fuck'' Twilight said before getting attacked by Photo with a knife in her hoof ''WHAT ARE YOU DOING DROP THE FUCKING KNIFE!'' Twilight yelled grabbed Photo with her front hooves ''PUT THE KNIFE DOWN'' the detective yelled before Photo tried stabbing Twilight in the neck causing her to throw Photo through a mirror.

Twilight found a tape in Photo's saddle and played it ''Hello Photo Finish i wanna play a game if the detective saves you from the Scalping Camera[ she'll arrest you for your crimes and the only way to stop here is by killing her.'' Stichy explained

Twilight went looking deeper into Photo's saddle she found a key Twilight headed upstairs and swearing she saw a box sitting on a table and she was right. When she opened the box she found 2 keys on was a candy key with a tag saying Sugarcube Corner and the other was a lockpick to a warehouse the unicorn decided to take both keys just in case

Time Skip

Once Twilight got to Sugarcube Corner she came across A.K Yearling wirting something down''What the fuck are you looking at huh, hey you.'' Yearling asked her angrily. The unicorn detective trotted down a small flight of stairs without even going over to the counter. ''Um excuse me can i help you'' Pinkie Pie Asked

Twilight found the door she was looking for it was covered in candy saying candy room when the detective used the key and opened the door all it was a supply closet. There was a box on the floor on top of the box was a picture of Rainbow Dash when Twilight opened it she found a Dollhead mask which is just button sunglasses and a stitched up mouth face mask finally she found a picture of Pinkie Pie.

''What the fuck is this stuff'' Twilight said to herself before playing the tape in the box ''Hello Mrs. Sparkle i wanna play a game the pony you see in front of you is in desprate need of help in the next room is the tools to her salvation her life is in your hooves but only she can save herself but to do this you'll have to hide your identity.'' Stitchy explained

Twilight put on the Dollhead mask briefly before taking it off ''I think i got a better idea'' she said to herself leaving the candy room

A Few Moments Later

Twilight camr back to entrance area of Sugarcube Corner finding Pinkie Pie talking to A.K Yearling telling her that she has to leave. Twilight pulled out a box of chocolate chip cookies from her saddle and putting down a trail of them. Pinkie's pet crocodile Gummy noticed the trail of cookies and followed it eating the cookies along the way which leaded to the candy room.

Once Pinkie got Yearling out of Sugarcube Corner she walked back to the counter just to realize that Gummy's gone ''Gummy where'd you go Gummy where are you'' Pinkie called out to Gummy before noticing the trail of cookie crumbs when she found Gummy he was chewing on the stitched up mouth face mask ''There you are Gummy'' Pinkie said going to pick up her crocodile only to see a charged up horn aiming at her

Another Few Moments Later

''Why are you doing this'' Pinkie asked Twilight ''Why'' The unicorn then handed Pinkie a picture on Rainbow Dash ''This was a mistake it was a long time ago i stopped doing this.'' Twilight started trotting back and forth ''no,no,no,no,no,no,NO!'' Twilight muttered under her breath ''You see that door'' the detective said pointing a hoof at the door with Feel What I Feel painted on it.

Twilight then handed Pinkie the candy key ''Here try this open that door'' the unicorn told Pinkie. Once the pink earth pony opened the Feel What I Feel Door she found the same torture chamber she used on Rainbow Dash, she tired to trot past Twilight only to be stopped by her. ''STOP STOP GET GET IN THERE'' The unicorn detective yelled charging up her horn smacking Pinkie in the face.

Once they were both in the room Twilight found the torture chamber had red lights and there was fish hooks with pictures of other pegasi Pinkie had tortured. Twilight found a tape and played it ''Hello Mrs Twilight for your third test the pony you see before you is a perpetrator of violence.'' ''You Sick Fuck'' Twilight said before resuming the tape.

''Her salvation is out of you hooves it's your choice if you want to put it into her own hooves and once you do you'll be a step closer to saving Princess Celestia and without you this pony's game can't begin, get her into position to face her demons she must feel what her victims felt.'' Stitchy explained

All of a sudden the TV in the room turned on showing footege of Pinkie torturing Rainbow Dash slicing off her cutie mark ''GET IN THE RACK'' Twilight yelled at Pinkie. The Pink Party Pony climbed onto the torture rack try to explain her action to the detective even though Twilight just igornerd her ''HURRY UP GET STRAPPED IN!'' The unicorn detective yelled at Pinkie

Twilight then walked up to the torture rack and put on the head cuff (or strap idk) ''What the hell's going on i'm sorry'' Pinkie said sobbing. Twilight then handed the pink earth pony 2 remotes with a single button on them, then played a tape she found on a cart before leaving the room.

''Hello Pinkamena i wanna play a game'' Stitchy said voice activating multiple saws coming down circular saws, chainsaw and buzzsaw blades ''You've tortured, caused trauma to multiple pegasi making them go through endless suffering, tearing their lives apart over some cheap baked treat. So you must feel what they felt but there's a chance you don't have to go through everything they went through but you'll have to sacrifice your eyes which had blinded you of the suffering these pegasi had to go through but if you don't in 60 seconds you'll be torn apart by all these saw live or die make your choice.''

Pinkie started sobbing uncontrollably pressing one of the remotes causing a blade to come down and stab her in they eye ''AHHHHHHHHHHHHHHHHHHHHHHH'' The pink party earth pony yelled but before she could muster up the willpower to blind herself completely.

3..2..1

The circular saws, chainsaw and buzzsaw blades launched forward tearing straight into Pinkie's chest tearing apart her digestive system causing parts of the large and small intestines to fly everywhere. the saw then moved onto the rest of her body causing blood and other organs to fly everywhere around the torture chamber.

Twilight left the candy room and headed back to the entrance area where she found Gummy on the counter and decided to leave him the rest of the chocolate chip cookies in the box before leaving Sugarcube Corner and heading for the warehouse.

Author's Note

In This AU Pinkie Pie actually owns Sugarcube Corner instead of just working and living there

Reminder: I based Detective Twilight Sparkle on Eric Matthews and Daniel Rigg from Saw since according to the Saw Wiki both of them have a temperamental and focused personality. Eric is one of my favorites characters from the Saw series but it kinda suck he was a corrupt cop so that why i made Twilight one of the only non corrupt law enforcers in her department
