A/N: Seeing as the ending was well received, and some people have asked for an epilogue, I decided: Why not? It's been a pleasure writing this story, and I hope you all enjoyed it. Also, I decided to do something different for this epilogue, I hope you like it.

Snowdin Town looked undisturbed, not a single monster or building was out of place. Which is good, seeing as I really don't like having to stitch the fabric of reality back together after all of these resets.

I was sat down, trying my hardest to blend with the snow. After what Sans had told Frisk, it was probably for the better that they didn't see me. They knew too much. Thankfully, the whole 'World is ending' fiasco was finally over. Unless of course, the child chose to reset once more. With the Legendary Artifact in its rightful place, I held the power. In a rather hasty decision, I bequeathed it to the human. I just hoped that they wouldn't abuse both their friends' trust, and mine. Sans would give them hell to pay if they did.

I heard their echoing voices from afar. "Now what? The barrier's still keeping us down here! We didn't gain anything from this!" Undyne seethed.

"'course we did. a kid got dunked on." Sans' lazy, deep voice spoke up.

"IF THERE'S ANY DUNKING TO BE DONE, IT SHALL BE DONE BY I, THE GREAT PAPYRUS! MASTER BASKETEER!" My other friend's familiar loud voice rang out.

Of course, the skeleton brothers both knew of my duties. I just found it funnier to mess with the taller one. However, the both of them knew how important it was to not divulge any information about me. Even Sans' offhand comment could have ruined everything, and made me a target. Without me, resets wouldn't exist. Because, nothing would fix the rifts created by the paradox of one person simultaneously controlling each and every timeline.

But what do I know? I'm a dog. There are no timelines left other than this one, my duties were complete. I was confident in Frisk's restraint. Chara no longer resided inside them. No more sneering, taunting insults. No more death.

Unfortunately, one loose end remained. And it took the form of a rosy cheeked human, who was currently face down in the snow. I approached them cautiously. It was about time I revealed myself to the world. I barked loudly, to alert the others.

Frisk was the first to arrive. I stretched up on my hind legs, determined to nuzzle them. They caught glimpse of Chara, and called the others over. They formed a circle around the child, unsure of how to proceed.

Toriel was the first to dare, taking a step forward.

For the first time in an eternity, I spoke once more. "Don't go near them." I warned, "As long as Chara exists, in any form, they're a threat. I'm not going to risk them going full circle."

Before I could conjure up the power to kill them, Toriel intervened. "Please, don't hurt them! I'll take care of them, make sure that whatever it is that you're accusing them of will not happen. Please, you can't just kill a child!"

Her pleading words struck something in me. If I was having to relenquish my control and pass the responsibility to them, why not?

With the exception of the skeletons, they were all visibly shocked from my actions. Frisk was the second to try stepping forward. "This cannot happen again. Ever." I growled, cautionarily. "I'm putting my faith in you, Frisk. Do not let me down. This is your last chance to put things to rest. If you get bored, or choose to become like them once again…"

"I will kill you as many times as it takes. Got it?" I adopted my most threatening voice. I think I got the message across, seeing as everyone, except Sans, looked terrified of me.

"Hey, lighten up guys. At least you got your happy ending, right Sans?"

"yeah, i guess. it wasn't the ending i had in mind, though." His smirk never wavered, as he pulled a bottle of ketchup from his hoodie.

"Well, it's the best that you'll get. Start treating it seriously." With that ominous threat, it was time to bid them a due.

"Right, it's time for me to go. I need to make sure the rest of the world's in working order. Maybe I'll see you all around." As I was talking, I realized that I forgot something.

Seeing as this was presumably the final timeline, it was only right that they got the ending they truly deserved.

"Before I forget, there's something I have to do. Remember the barrier? Well, the former royal scientist gave me a secondary purpose. Only to be carried out when I stabilised everything, ya know? If the timeline that I chose to settle down in, either by choice or the fact that this is the last one, the barrier was still up, Gaster told me to break it. But only as a last resort, because my powers? They'll be gone. All that will be left is a talking dog. Do you understand how much trust I'm putting in you, Frisk? If you go against me here, everything that has ever existed will be destroyed. And there won't be any solutions to bring it back. Determination can't bring you back to a world that doesn't, and technically never has, existed. But if somehow, by some miracle, this world does return, I'll make your every moment a living hell. I'm not confined by physical limits, so I'll hunt you anywhere you go."

I pointed a paw at Frisk. "So if I do this, I need you to promise me something. Promise me, that this is the last time. Promise me that you'll live out your life naturally, no more resets. Give me your word, and I'll use what power I have left to destroy the barrier."

They stepped forward once more, and scratched me behind the ears.

"I promise, Toby."
