Chapter Text
Abaddon has lived through the begging of time so many times that he'd lost count
It was torture and not the good kind that he loved so much
Having to live through the entire history of earth was tiring and seeing Nathan die over and over again and not being able to do anything about it was exhausting
Nathan's spiral started long before he met Abaddon
Every time the date of Nathan's death changed, sometimes it was the beginning of August sometimes it was the end, sometimes a completely different month
Abaddon never knew when that fateful day will happen so every time a few months pass since their first meeting he starts living on edge, preparing himself to find the humans cold, unmoving body either on the ground or on his chair
The method never changed so that was a comfort at least
Abaddon has seen a lot of dead bodies in his long lifetime but Nathan's? He didn't like seeing it, hated it even
No matter how many times he's seen it he's never ready for the day
And the few days of loneliness as Nathan's ghost was forming he usually spent hiding in the vents
But as much as he wished he could stop Nathan, change his mind somehow or just hide every single pill bottle that's in the hotel he simply can't
Nathan's suicide is a kick starter
Nathan kills himself, Katherine, Esther and Ben move into the hotel, they live there for a year and then the acolytes come
He still haven't figured out how to make it past the acolytes but he'll get there, eventually
In the recent timelines he's repeated he started trying new things, mortals of the 21st century have some interesting creations
He'd recently got a liking of these so called "board games" especially the one that Nathan had called "chess"
None of them knew how to play it though but they learned together, it was fun
The current timeline he was in was the also the one he finally decided to try the clothes that Nathan had bought him in every other time line but never wore them
Just one day to see how it feels like
That's why now Abaddon was dressed in a light green shirt that was just a bit too big for him, black loose shorts and gray socks, no shoes
His regular clothes were neatly stuffed into a vent in Nathan's room
The clothes were comfortable enough, didn't restrict any of his movements which was nice, they still didn't feel as good as feeling the hell fires lick his skin as he sended a yet another dammed soul for eternal torture but they will do
So now Abaddon, in his fresh new clothes was sitting under the desk at the reception and just drawing, he wasn't drawing anything specific, just some animals but he knows that Nathan will proudly display it on the fridge like he always did, he didn't understand why Nathan bothered with doing that
As he sat there engulfed by the shadow he heard the front door open, seems like it's one of those rare days where the hotel actually gets a customer, he should probably go get Nathan to handle that he didn't feel like interacting with any mortals let alone the annoying customers who are always complaining and very much deserve the hottest pit of hell to burn for all-
"Nathan?" Abaddon recognized that voice
But that was impossible she shouldn't be at the hotel for at least another few months
That's how it always goes, Nathan dies first and only then Katherine comes to Undervale, never earlier
Abaddon peaked out from behind the desk and there she was
Katherine Freeling in all her glory, standing in the hall of the hotel she definitely shouldn't be in, at least not yet, but there she was
Disobeying the previous time lines for some unknown to the demon reason
That was bad, really bad. She was not supposed to be there why is she in the hotel? And where was Ben and Esther did she leave them with her husband? Her parents? Was she alone?
Will her breaking pattern somehow affect Abaddons ability to save them from certain doom and regaining his powers?
Well, maybe Abaddon could have some fun with the current odd situation, the time line has already broken what's a little more chaos gonna do
Abaddon smirked and hopped onto the chair, startling Katherine
"Welcome to the Undervale hotel what do you want?" He asked in a bored voice, he was standing on the chair therefore he towered over Katherine, meaning the mortal had to look up to look him in the eyes, that felt nice
"Oh uh hello there little boy" well that was an awkward welcome
"Abaddon" the demon corrected her, she didn't know him yet, she didn't know who he was and what could he do
"Right Abaddon, are you even supposed to be here?" She pointed at the reception desk and the demon just shrugged, Nathan never said anything against him being by the reception desk, and even if he did Abaddon would still be by it. No mortal will dictate him where he can and cannot go
"Alright" Katherine said slowly "do you know where I could find Nathan Freeling?"
Ah makes sense she was looking for her brother
"Yeah he's outside" working on that hedge he will never finish
"Great great uh do you know when-" that's when Nathan decided to stride into the hotel grumbling something about annoying plants
He immediately lightened up when he saw his sister
"Katherine! What are you doing here it's so good to see you" he threw his hands into the air and trotted over to trap Katherine in a bone crushing hug
"It's good to see you too Nathan" Katherine laughed when the man finally let her go "I gotta say this place looks really nice"
"Ah you know how it is gotta keep it fresh for the customers"
"You get customers? No offense but Undervale isn't exactly a tourist attraction"
"I do actually, it's mostly people who got lost or just need a place to stay for the night" Nathan explained
"That's great, I do have a question tho" she turned back around to point at Abaddon who was still standing on the chair "who is that?"
"Ah I see you met Abaddon" The human smiled brightly and walked over to the demon "were you ok here all by yourself?"
"Of course I was I can handle myself" Abaddon hopped down the chair "I'm gonna go eat some yogurt"
"We're out"
"Agh" stupid human always forgetting his delicacies "do we at least still have froot loops?"
"Yeah we still have a box" Nathan nodded
"Then I'll just eat that" and with that he left to go to the kitchen
When he closed the door he heard Katherine and Nathan talking about something he didn't hear
He didn't really care about what they were taking about if he was going to be honest, he just wanted his froot loops
That wretched vessel of his was so small he had no other choice but to humiliate himself with climbing the counters just to get to the cupboards
He pulled himself onto the counter and slowly stood up on it, he opened the cupboard and took out the box of cereal, closed the door and slipped back onto the ground
Getting milk was much easier since Nathan always left it on the bottom of the door of the fridge
Abaddon got the milk, and climbed onto the chair, kneeling on it
He then first poured the cereal into the bowl and them milk
It was explained to Abaddon that for some reason humans have very heated debates over which one goes first
Abaddon personally could not be bothered to care which goes first
After finishing the first bowl and getting started on the second Nathan slowly walked into the kitchen
"Hey bud, I have some news" well that was a good start "I told you about my sister and her kids right?"
"You did, a lot, with painful details" the demon deadpanned, the amount of times he had listened to Nathan going on and on about the three was just ridiculous
"Alright so, Katherine is getting a divorce and her soon-to-be ex husband kinda kicked them out of the house"
Another change from all the other time lines, usually it would be Katherine's ex (that he never bothered learning the name of) moving out of their house and the Katherine, Esther and Ben living there until Nathan's death
"And?", Abaddon shoved a spoonful of froot loops into his month
"And all three of them will be living at the hotel for the time being, until Katherine gets on her feet" the length that Nathan will go for his younger sister is impressive
"Alright, where are the kids now anyways?" That was bothering him
"Oh Ben and Esther are with our mom now" ah that makes sense, Katherine isn't the type to leave her kids alone in the car somewhere
Abaddon did get trapped in a car that one time, cursed child safety locks
"When will they be here?" He asked calmly
"This evening, they will be staying in some of the spare rooms"
"Alright"
"You're really fine with it" ah, of course Nathan wanted to make sure considering the fact that in his mind it will be the first time Abaddon will be around other (alive) people for an extended period of time
"Why wouldn't I be, they're your family right? Family helps family" was quoting Nathan back playing with his emotions? Maybe
"Alright that's great" then he left, probably to inform Katherine that she could stay
This timeline just keeps getting more and more interesting
