    Summary

    (title from 'Laplace's Angel' by Will Wood)

    Killer wakes up with his eyes stuck shut, unable to see. Slipping into Stage 3, he fights with all he has left to go talk to one (1) singular person. That's all he has to do.

    Why is it so hard?

    Summary

    Blue really was planning on telling his friends, really! It was just... hard to find the time! Error needed lots of love and care and attention after all, especially given how much of his own privacy and comfort he'd given up to be with him like this.

    Unfortunately, it seemed like his friends decided to unintentionally find the time for it themselves! At the worst possible moment.

    Summary

    Blue thought he had a pretty magnificent life. He had the bestest ever friends in Dream and Ink (even if the two sometimes still needed some guidance as to how living with mortals work), an amazing brother who he loved and respected very much (even when Honey could still be silly about a few things), and best of all, a datemate whom he loved very, very, very much..! Even if they had to be discreet about their relationship.

    At least, until one night of passion and poorly managed intent had left them with something that they couldn't be discreet with.

    As he prepares to take responsibility for his actions and dedicate himself to a domestic life with his beloved mate-to-be, Blue is faced with only one question:

    How does he break it to his friends and family that he knocked up the Destroyer of Worlds?

    Summary

    You spend most of your days at Ebott's aquarium. Not just because you particularly loved marine life, but to spend time with the ones you felt truly understood you.

    Sure, they kill people every other week, but to be fair..

    You'd probably do that too if you were kept within a glorified glass box.

    Summary

    Waking up so much smaller than you fell asleep is a good reason to worry, but here are a couple bigger reasons to freak out...

    You're a Gaster Bitty, and not your run of the mill Goopy Gaster, you're a fuckin Bitty looking just like before he fell in the Void, with monster reserves to match. Turns out there was never a model of Original Gaster in the bitty releases. Meaning you don't have to rely on no "Owner" to make sure you don't dust...

    And it does no good for your soul when you realize you've been accidentally adopting every hurt skeleton you see when all you thought you were doing was sharing your Magic reserves with a hug so the other bitties you know that don't get affection won't dust...

    What do you mean that the Grillbitties you saved were trying to become your mate? No way, they're just being nicer than usual! And I didn't happen to magically adopt all those hurt skeletons that are definitely not my sons- "Dad?" "Yes son?" "You are thinking too loud, stop it." "... Yes, son."

    Summary

    You fell into the Underground as a child. You spent a few years there, growing up with the skeleton brothers. Life wasn't great, painful at times, however you had your family with you. A change came to your life, one where you were surrounded by alternates of your skeletons. They were nosey, pushy, and much louder than Papyrus. They were nothing like your skeletons, and you very much didn't approve. You didn't know how to act, you didn't know if you could trust them, didn't know how to trust them.

    There were too many factors. Monsters were there that you couldn't be around. But maybe.. some can help you?

    Summary

    The taste is what drives you. The smell motivates you. The feel of dust between your fingers, the sound of screams and begs echoing in your ears, watching them dissolve right before your eyes.

    The sensation of LOVE filling your body.

    You had long grown used to the feeling of gaining level after level, over and over all for your entertainment.

    When it was all ripped away from you, the emptiness was too agonizing for you to truly focus on your newfound lack of flesh and the magic seeping from your bones.

     

    Kill first, ask questions later.

    Summary

    He thought that the radiation would kill him. He thought that his time as the Doctor would come to a sad and brutal end. He was wrong. And that was so much worse.

    In his efforts to find himself, and without his companions, he accidentally stumbles onto a monstrous civilization miles below the Earth. With his newfound DETERMINATION and some new allies, he'll come to realize what it truly means to be a friend, and learn how to live his last lives with his head held high.

    And make sure that, just this once, everybody lives.

    OR

    Undertale but the Tenth Doctor replaces Frisk. Fluff, angst, AUs, and timeline shenanigans ensue.

    *No knowledge of Undertale or Doctor Who is required, though it is helpful if you've experienced at least one of them.

    Summary

    You, as the owner of Bouquets and Bells, have run your boutique with love put into every stitch. When monsters had first broke onto the surface, you hadn't really thought too much about how it would effect you and your business in the long run. To your very welcome surprise you meet two monsters who are interested in having a wedding and need your help to make it perfect. Along with them, they bring a whole crew of skeletons who are DETERMINED to weave themselves into your heart. Your failed engagement years ago had left scars that still marred the surface of your SOUL, but maybe they'll just find that beautiful.

    Also way too many puns.

    Summary

    They say, when you're starting to Fall Down, you should start carrying around something you love. Not so that whoever has the misfortune of needing to scatter your dust has something you love on hand, but so that you have something close-by to stave off the inevitable while you get your affairs in order.

    Sans doesn't really have anything he loves that's small enough to just carry around. He doesn't love things.
