    Summary

    After thousands of unrelenting resets, Frisk has finally acheived it- the truly perfect ending. Asriel was saved, Chara was here and she even brought back the long lost W.D Gaster back from the void! With the help of everyone, they even got Goatdad and Goatmom to be together again! And to spruce things up, they all live in one big house together. Everything felt like it was to good to be true, just perfect. Everyone should be happy, right?

    Sans's night terrors has gotten worse over the past few months. The comedic skeleton avoided all of them to settle it by himself but his dear family was sickly worried.

    And so a memory machine was built, though Frisk had a baaad feeling about the turns of event.

    Summary

    Sans is conflicted by night terrors and vague memories from previous timelines gone wrong. While they're starting to become more vivid, soon he starts to notice deviations from what he's grown accustomed to and Papyrus does something unusual that changes everything.

    With the River Person out of commission, Sans accompanies Grillby on a replenishment run through to New Home, all while wrestling with a feeling he just can't break about his long-time friend. As he gets to know Grillby in a newer light along with some changes that have come up due to past medical abuse, it's becoming more and more apparent that something or someone is interfering...

    Summary

    His mind was breaking, scolding, disintegrating, a melting pot of helplessness....

    Nothing.

    There was no running, there was no hiding, there was only burning pain.

    He thought his brother loved him but that was a lie. He practically raised Pap- Boss and now he was his dog. Trained to be obedient against all odds.

    He thought things couldn't get any worse but he had been very, very wrong.

    If it wasn’t Boss tormenting him it was a sadistic little flower or a kid in a little striped sweater.

    But as time when on, Sans couldn’t bring himself to care anymore. He was just so tired. He just wanted a good sleep. Was that so much to ask? Just one night, just one, where he wasn’t plagued with night terrors only complete numbness. Only wanting a small piece of serenity and- who’s that?

    “I’m sorry. I’m so sorry I didn’t… I’m sorry.”

    What?

    Summary

    I discovered the PTA Sans AU on Tumblr and now it won't let me go. So here you have it:

    Little shorts placed in the AU where Sans adopted Frisk together with Toriel, Toriel is running the local school and Sans was roped into going to the PTA meetings.

    Let's just say that he gains a lot of motivation during those.

    (Now with plot: A secret project between two nerds, an ongoing inspection and the insanity that comes with monsters living together with humans.)
