Chapter 10 Papyrus' Secret

You woke up at noon. You were shocked that you had slept that long, and that the skelebros had let you sleep this long. Papyrus wouldn't stand it...... oh wait! Papyrus had to do what Sans said! Otherwise Sans would dust him! That made sense now. You got up to go see how the boys were doing. You went downstairs, only to find..... nobody. They must have gone out. You decided to wait until they came back.

(Time skip brought to you by the best guy in the history of the universe, L.S., my boyfriend!)

When Papyrus and Sans came back, you were majorly pissed.
Where have you been? I woke up and you two were gone! I was worried that you might be dead!
You aimed your speech at Sans, knowing that Papyrus didn't make the decisions anymore. Then, you saw it. The massive amounts of dust, monster dust, on Papyrus. And the sharp, jagged bone that he held, coated and dripping with the blood of innocent monsters. You were shocked. Papyrus didn't have a mean bone on his entire body! Maybe it was Sans' bone? And Sans gave Papyrus it to carry home? Or... no, Papyrus couldn't kill like that. Could he? It was possible, though highly unlikely.
Sans? What's that on Papyrus' body?
Hmm? Oh, yeah. Papyrus killed some monsters for yah. They wanted to....ah....how should I say this.....kidnap you and hold you ransom so that they could take Paps so believed 'innocence'. So, he killed them. Apparently, he is a ya-mmmpphhhh!
Sans was muffled by Papyrus putting one gloved hand against his skull. Papyrus pulled Sans aside to talk to him. You decided to listen and see what it was about.
SANS! PLEASE DONT TELL HER! 
Tell me what?
Papyrus didnt realize that you could hear him. He jumped, and turned to face you.
W-WELL, YOU SEE, I UM, AM, UM, HOW DO I SAY THIS, UMM,...
He's a yandere for you, Frisk. And for me, turns out. Who knew? He's been one for me since he learned to battle, and for you since you came to the underground.
Wow Paps. I didn't know you were so secretive.
W-WELL....UM.....I GUESS?
Hehe. There's nothing to be afraid of Paps. I'm a yandere for you to. And Sans probably just wants to protect you.
Yep. Anything for the bro. And I can stop hurtin him now, being that he isn't trying to take you away from me.
N-NEYHEHE! I LOVE YOU TWO SO MUCH!
Aww, we love you to Paps. Now, let's get you cleaned up. We can't have our guest thinking we're murderers, right?
Sans winked at you, knowing full well that he was a yandere, classified as a murderer. But...
Guest?!
