- OK SO UNDERTALE TRUE PACIFIST TIMELINE YEAH

- BUT SOMETHING GOES HORRIBLY WRONG AND NOW THE MAIN CHARACTERS INCLUDING FRISK ARE 11 YEAR OLD KIDS AND GET THESE LETTERS TO A PLACE CALLED HOGWARTS

- AND THEN ALPHYS JUST STARTS SHRIEKING IN PURE FANGIRLING GLEE BECAUSE SHE TOTALLY FOUND A SET OF THE HARRY POTTER BOOKS IN THE DUMP AND HELL YES SHE'S GOING TO FRICKEN HOGWARTS

- AND CHARA'S THERE TOO AND TORIEL AND ASGORE ARE JUST TRYING NOT TO CRY BECAUSE THEYRE NOW THE SAME AGE AS THEIR DEAD CHILD

- RIGHT AND THEN THEY GET THERE AND GET SORTED INTO THEIR HOUSES AND THEN HALFWAY THROUGH DINNER THESE TWO V E R Y  F A M I L I A R SKELETONS RUN IN PANTING LIKE "WE'RE HERE SORRY"

- AND ITS 12 YEAR OLD INK AND DREAM AND THEY TOTALLY JUST CRASHED INK'S FLYING CAR INTO THE WHOMPING WILLOW AND SUDDENLY SANS NOTICES BLUEBERRY DOWN THE GRYFFINDOR TABLE DOING A FACE-TABLE (when a face-palm isn't enough :))

- AND THEN HE HEARS SNICKERING FROM SLYTHERIN AND SEES NIGHTMARE AND ERROR AND DUST AND KILLER AND HORROR AND CROSS LOOKING LIKE KIDS AND CACKLING AND wait where are Nightmare's tentacles? And Cross's knife? Also why is Error letting Killer hold on to him while he dies?

- So like after dinner he goes up like "Ink?" And the Star Sanses turn around and Ink Jr.'s like "um do I know u?"

- 'Ok wtf' "N-no; I guess I just thought you were someone else."

- Well so something's obviously wrong here

- And apparently there's no big drama here like ol' Voldy But most of the other major plot points in the book happen minus Umbridge

- Lmao Alphys being anxious for their fourth year then being relieved as soon as she walks into the Great Hall. Then starts cursing Umbridge up and down when the gang asks her what her problem is

- OH AND FUCKING FLOWEY IS CAUSING TROUBLE WITH PEEVES BECAUSE YES

- Right anyway so Sans realizes that all the other Sanses and a few Papys and Toriels and Asgores are here but they all have their nicknames as their like actual names and have no idea why Papyrus keeps calling them "SLUDGY SANS" (Nightmare) or "LAZY ME" (Swap Paps)

- *gasp* THE TIME KIDS ARE ALL THE SAME AGE AS THE OTHERS AND ARE LIKE THE WEASLEY FAMILY

- Actually wait where are the main characters of the books? Oh well. At least the teachers are all here.

- Oh, but in this one Quiditch match in Sans' first year Dream breaks his arm falling like a dumbass and Lockheart's like "Oh LeT mE hElP"

- Cue all of the skeletons in the school going fucking nuts when Dream's broken bones dissolve.

- "YOU DISSOLVED HIS FRICKEN ARM WHAT THE HELL-" - Nightmare being extremely concerned despite always being a shit head to his bro.

- O ye whatever's going on here, apparently Night and Dream don't have as sour a relationship cuz Night didn't eat any funky apples; he's just a jerk. Most of the time but seriously he's concerned about Dream's arm

- Before I forget Ink Jr. can feel emotions he just doesn't get social cues, and Nightmare and Dream Jr. are just really good at reading emotions even though they don't actually have any magic powers aside from basic wizard skills

- "Akshcjdbajchrbricjs" - Sans having a small PTSD attack from Genocide runs

- "I could draw it back on-" "INK NO" - Ink offering to help Dream and Blue knowing it might end horribly wrong

- They're not taking any specific roles btw; their just the trio in place of Harry and Ron and Hermione.

- Oh my god guys imagine this:

* Asgore being an absolute pro in herbology

* Undyne in her second year protesting that she doesn't need to take DADA because she's got magic spears and demonstrating for the class by smashing a skeleton accidentally then getting sent to Dumbledore's office

* Alphys being the only non-Slytherin Snape doesn't hate because she's a fricken pro at potions and for 'some reason' isn't fazed by his being a jerk

* Papyrus protesting that it's much healthier to run than to sit on a broom and fly but Madam Hooch just being like "Yeah well this isn't health class so get over it" and later Papy reeeeally wanting to try out for the Gryffindor team because ITS FRICKEN AMAZING OKAY HE WAS WRONG

* Sans learning to transfigure things into bottles of ketchup and doing it literally every fricken class with McGonagol and having a bunch of pieces paper (or y'know a notebook) purely for that purpose

* Sans and Papyrus sleeping in the same dorm despite Sans being in Ravenclaw like Alphys and nobody saying anything because seriously if this big skele needs his bedtime stories they weren't going to do it. Also Sans can teleport so there's not much they can do

* Also yeah Sans can teleport around inside the castle but can't teleport out. And he learns the castle's secret passages very quickly.

* Toriel being like Madam Pomfrey's personal assistant but also being Hagrid's favorite student because GOAT MONSTER SO FLUFFY and she's very enthusiastic about CoMC.

* See also Tori, Undyne, and Paps pressuring Sans into actually walking to class like all the other good children

* Napstablook thinking he's not welcome the classes and then being delighted when Professor Bins is just like "Young man please have a seat" and then being the only one who can actually pay attention to the ghost professor.

* Mettaton being in Divination just because he wants to convince Trelawny (can't spell her name 😢) that she could be a STAR with how dramatic she is and then getting into deeply philosophical discussions with her after a few months because he's actually enjoying the class

* Mettaton also trying to get Peeves to use his poltergeist powers to like make a dramatization of Bohemian Rhapsody with those suits of armor because seriously

* Everyone being elated to learn there's an astronomy course and ending up all in the same class period

* Asgore trying everything except love potions (because that's r u d e) to get back with Tori and Toriel just completely ignoring him

* Sans being the school's go-to guy for help with their prank/pun/joke war.

* Chara and Frisk being the real trouble makers-even more so than Nightmare Jr.'s group.

* Alphys being upset when she isn't as good at Charms as she hoped she would be and then Undyne trying cheer her up by summoning a TV and a DVD player and their Anime collection before realizing that THERE'S NO ELECTRICITY IN THE DAMN CASTLE whoops. But Alphys being amused and feeling better.

* AND EVERY WEEKEND THEY ALL HAVE A PICNIC By THE LAKE WITH EVEN FLOWEY BECAUSE YESYESYES

* Also Temmie Flakes suddenly being an option at every meal and somebody going to the kitchen to find Temmie helping out and working for pay with Dobby because innocent children working for a cause (new socks and colleg)

- OK RIGHT AND THE UT CAST ALL GET USED TO SHIT AND THEN ALL OF A SUDDEN IN THEYRE SIXTH YEAR A MUCH OLDER AND MUCH MORE BATTLE-EQUIPED INK JUMPS OUT OF AN INKY PORTAL IN FRONT OF SANS AND THE JUNIOR STARS AND AT FIRST OLDER INK IS ALL "Sorry I didn't get here sooner! I don't know WHAT the fuck is happening-" AND THEN HE NOTICES INK JR. THEN DREAM JR. AND BLUE JR. MAKE THIS FACE LIKE 'oh shit'

- AND THEN OLDER DREAM AND OLDER BLUE POP OUT OF THE PORTAL JUST AS THE TWO INKS START FANBOYING OVER THEIR CLONE AND 'we're never getting them apart are we'

- "Can someone please tell me what the fuck happened" - Sans standing in the background being confused

- Alright so now Ink Senior is back at attention and the Junior Stars start chatting up a storm with the 'new' Dream and Blue while the Creator explains what little he knows about why they're all chilling in Hogwarts

- Which amounts to "Soooo I think basically what happened was our multiverse and the Harry Potter universe kinda melded together somehow? Dunno why or how but we can prooobably fix it."

- Nightmare Jr.'s group happen to be looking for someone to mess with and suddenly being like "What the shit why am I seeing double"

- Welp now Dream Senior is trying not to pick up Smol Nightmare and making sure he never goes bad like 'this is now my bean do not touch my bean do not ruin my bean do not encourage my bean to do evil or you will find urself wif an arrow in ur face' because smol Noot Noot is actually kinda cute in a small bean sort of way.

- Even though he's like 17 but eh teen vs 170 year old

- And then Ink Senior is breaking the Bad Children's world view while Blue Sr. Is just like "Ink we talked about this"

- Papyrus and some of Sans's buddies coming around the corner and being like 'whomst the heck' except Paps who's like "OH HELLO INK! HOW ARE YOU DOING?" And Undyne being like "I thought HE was Ink *motions to Ink Jr*" and Paps being like "WELL YES BUT ALSO SO IS HE *motions to Ink Sr."

- Then Error Sr. popping in like "WHAT THE HELL I'VE BEEN STUCK IN THE ANTI-VOID NOT ABLE TO DO ANYTHING FOR LIKE FIVE Y E A R S AND NOW THERE'S TWO OF ALL OF US AND WE ALL GO TO A FICTIONAL SCHOOL WHAT THE F U C K IS WRONG WITH THE WORLD"

- Error Jr. just being like "Jesus dude calm down" and Error Sr. Like "STFU YOU ANOMALY" AND NOW NOOT JR.'S GANG IS ON DEFENSE BECAUSE YOU DO NOT MESS WITH ONE OF THEM UNLESS YA WANNA PUKE S L U G S

- Ooooh yes and also Ink Jr.'s wand snapped when he crashed into the Whomping Willow and he totally tried to curse Error Jr. later and ended up puking slugs

- He laughed hysterically about it later but at the time he wasn't happy

- RIGHT ANYWAY ERROR SR IS NOW BACKING AWAY FROM THE ANGRY JUNIOR BADDIES AND THEN AN ACTUAL NOOTCTOPUS DROPS OUT OF THE FUCKING SKY EVEN THOUGH HE DIDNT EVEN DO ANYTHING BECAUSE REALITY IS TRYING TO MESH EVERYTHING TOGETHER AND HIS GANG IS THERE AND NOW THE JUNIOR BADDIES ARE SO DELIGHTED THAT THEY HAVE ALTERNATE VERSIONS OF THEMSELVES THAT THEY FORGET ABOUT ERROR SR. AND NIGHT JR. IS LIKE "DUDE YOU LOOK SO COOL AJDIDIEH"

- Meanwhile Ink Sr. and Sans and Papyrus are trying to figure out what the hell they can do to fix this

- THEN INK SR.'S LIKE "well maybe we just gotta wait until you graduate" and Dream Sr.'s like "Ink you realize that at this point this is its own AU meaning the original Undertale timeline got completely fucked over"

- Sans is like "eXcUsE mE wHaT"

- Flowey popping out of the ground like "did I just hear somebody say timeli-OH MY GOD THERE ARE MORE OF YOU SMILEY TRASHBAGS"

- The Chara and Frisk coming too like "Flowey be nice also what's going on"

- Ink explaining again

- Frisk bein like "What if we just reset"

- Sans like "NO"

- The Jr.'s being extremely confused like "reset? Reset what, exactly?" And only being more confused as the Sr.'s act like this is normal.

- "Actually Sans they might be right" "ndmdjdgsnxjdBUT WE-" "Sans I promise I'll do another True Pacifist." "...fine."

- "GuYs SeRiOuSlY wHaT's GoInG oN"

- AND THEY RESET BUT THEY JUST START AT THE BEGINNING OF THEIR FIRST YEAR AND SANS IS LIKE "well that's one way to stay on the surface lmao" and Frisk and Chara and Flowey like "WHAT THE F U C K"

- And also the rest of the UT cast being like "wait weren't we just like sixteen why are we eleven again"

- AND SUDDENLY

- INK JR. POPS UP LIKE "GUYS I JUST LEARNED A NEW TRICK AND ITS SUPER COOL" AND HE JAST JUMPED OUT OF A PUDDLE IF INK AND INK SR. COMES OUT BEHIND HIM WITH THE REST OF THE JUNIOR STARS AND FUCK YEAH INK SR TAUGHT HIM THAT then Jr.'s like "so hey anyone wanna explain what the shit just just happened and why we're in our first and second years again"

- "NnnnoOoooooOoOOOOoo" - Sans, Frisk, and Chara while Flowey is just like "fuck you"

- And now everyone who's supposed to exist are like 'welp guess we're going through this again' while the Junior Stars are like 'wErE kIdS aGaIn LmAo'
