Undertale spoilers!

I don't own Undertale.

It's probably better that way, on reflection.

I took the escalator upstairs, and looked for a suitable weapon. Something with a bit of reach. I checked under the bench that had Mettaton's robot body on it.

"Ah ha!" I said to myself.

Under the bench was a box full of sharp objects. One in particular caught my eye – a long carving knife. Why Alphys had this, I'd never know, but it had better range than my fists and might be enough to scare some people off without killing them.

I took the escalator back down and looked around. Alphys was nowhere to be seen, probably reading my notebook.

The heavy sliding door opened and the burning Hotland air engulfed me again. I heard a heavy sigh.

I whirled around in surprise, to see a short, fat skeleton in a blue hoodie, black shorts and slippers.

"Sans." I said calmly, expecting a fight. "What do you want?"

"you need to remember something." Sans said calmly. "karmic retribution isn't your friend, or your ally. karma doesn't take a side. it's a tool. it's likely one of the most destructive tools in existence. but just because you wield it, doesn't mean it can't destroy you.

"You sure seem to know a lot about it." I said.

I turned around and looked over at the lava. He was right, really. It had already stopped helping me. I was fairly certain that murdering the king and stealing his SOUL would count as evil. There was no way out. I was also sure that doing good deeds just for karma wouldn't help either – I'd have to really mean them. But if I looked deep inside myself, I would know that I didn't really care about these people. These monsters. All I wanted was to escape.

"I'll be going now. There's only one way out, right?"

Silence.

Sans was gone.

He acts like he's a god or something. I wish I could crush his stupid head into the ground.

…

Am I going insane already?

I walked through the route Alphys had explained. Go through the Core, then you'll find yourself at the palace. Somewhere there would be the barrier.

Walking wasn't hard. It just took time. I didn't have a map of the core, but after ten minutes of checking every passageway, I found one that looked right. A long metal bridge, with an elevator on the other side. I crossed the bride, and stood in front of the elevator. It was strange to see something so ordinary, so human, after everything I'd been through.

My reflection in the metal door stared back at me. A dark shadow appeared behind the reflection, and I turned around to look. Nothing there. Just a trick of the light.

I pushed the button and it beeped gently. The doors slid open and I stepped inside.

The elevator ride was short, but felt like an eternity. Every second seemed to drag. Finally, the doors opened, and I found myself in a dimly lit corridor made of grey bricks. It was familiar somehow.

I walked slowly through the corridor, the sound of my footsteps echoing against the walls. My heart was in my throat. I could sense that my journey was finally over. I was filled with Perseverance.

A few minutes of walking later, I reached a tall, grey brick house. That jolted my memory. This whole place seemed to be the same design as the Ruins. Oh, duh. The Ruins. That must have been the king's old palace. The exiled queen lived there because it was familiar to her. And so this… this was the house of the king.

"Howdy!" came a high pitched voice.

"No." I refused to believe that it was him.

"It's me, Flowey!"

"Who?"

"Ugh, I messed up my entrance."

I spun around. "ASRIEL? I KNOW YOU'RE THERE!"

"And how would you know that?"

I looked down to see Asriel looking up at me. He had a malevolent, curious glint in his eye, as always.

"I can see it. You messed up your 'entrance' and went back to make sure you looked cool."

"I… that didn't happen."

There was a short, comical pause between us that really didn't fit the mood.

"Anyway. It's me, Asriel! Or rather, not Asriel anymore."

"You mentioned 'Flowey'."

"That's right! I'm a new person. I wiped my slate clean. I've asked for forgiveness for my actions. And I meant it. Now, I'm a new person. Your power has no effect on me!"

"That's not how it works. You can't just decide that you're innocent." I spat. After all, I was the wielder of Karmic Retribution. If anybody had the right to judge anyone for their actions, it was me.

"Oh, no. That's exactly how it works. You have to really feel sorrow and genuinely ask for forgiveness. And I did, for a while. I had to get real close to the king's stolen yellow soul to make it work."

For a moment, we were both silent. We both stared at each other, the air rippling with our hatred for each other and ourselves. I raised my knife. Asriel – no, Flowey didn't move.

I'm sick of dealing with your shit. I'm going to mash your stupid flower face into the ground. I'm going to kill you over and over, no matter how many times you RESET.

I swung the knife downwards, and Flowey, leaned to the left. Time slowed to a crawl. I could see my blade, falling sluggishly towards the ground. It was going to hit him.

It was going to hit him.

Shit.

My blade effortlessly sliced off a petal.

"Hehehe. You missed. Idiot."

I suddenly felt a gut-wrenching pain in my stomach. I doubled over, coughing blood. "W-what did you do?" I demanded, fury burning in my eyes.

"Nothing!" Exclaimed Flowey. "You attacked an innocent, and now Karmic Retribution is punishing you."

"No… I can't die here!" I was forced to my knees as the pain spread to my legs. The purple energy rippled along my skin, bursting and tearing it open.

Perseverance.

I swung the knife again, missing Flowey by a hair.

"Hehehehe! Hahahaha! HAHAHAHA! YOU IDIOT!"

Heavy footsteps echoed up ahead.

"No! You always ruin everything!" Hissed Flowey.

It must be the king!

For the first time since I was caught by Tuffet, my mind was clear. I had to survive. I had to keep going. I had to persevere.

I slumped onto the ground and watched Flowey disappear to avoid being caught by whoever was coming. I looked up to see an old goat man, like Toriel, looking down at me. I couldn't tell if he was angry, or sad, or surprised. Karmic Retribution had spread to my eyes, blurring my vision.

As I closed my eyes for the last time, I felt my SOUL leave me.

And Flowey didn't have it.

Oh, boy! Purple is deaaaad!

I'm pretty sure you all knew it was coming. I mean, they were dead at the end of Undertale, nobody should have been surprised.

Also, thinking about writing one for the Green Soul as well.

Anyway, that's the end.

Or is it?

OOOOOO SPOOKY GHOST NOISES
