Chapter 6 Undyne

You heard Undyne banging on the door.
"Punk! Lemme in! Papyrus didn't show up for training, and I know your in there! Open up, or I'll have to break down the door!"
You continued crying, not out of fear, or sadness, but joy, for Sans had done this for you. You heard a crash, and then footsteps stomping up the stairs. Undyne threw The door open.
"There you are punks! Wait, what's with the dust? And... Papyrus' scarf!? You killed him Sans! I know you did! Why is Frisk crying? That's it punk! Ready!?Fight me!"
Sans and Undyne started to fight. Undyne threw spears, but Sans caught them with his magic and threw them right back. You reached into your inventory for the Burnt Pan.
You equipped the Burnt Pan
You walked behind Undyne, and got ready to knock her out.
"Wha- punk?!"
You swung the pan. It hit Undyne directly on her cranium. She fell to the ground with a thunk. Sans looked at you in amazement.
Woah, kid. You are amazing at protecting me. Kid?
You were looking down at Undyne, her limp form not dust already.
Give me a knife.
Wha? Kiddo? You okay?
Give. Me. A. Knife.
Okay, okay, no need to get angry about it.
Sans gave you a bone knife. You started stabbing Undyne. Eventually, you turned her to dust. Sans looked impressed.
Ah, kid? Why'd ya do that?
I did it, because I love you.
Wha?! Kid?! You, You don't mean Level Of ViolencE, do you?
No Sans. I love you. As in, kiss love you.
Heh. I love you to kiddo. Now, how about we clean up this dust. Don't want anyone else to know. Heh.
You and Sans started cleaning up. The room went dark as you kept cleaning. Sans had turned off the light.
Sans? What's going on? Why did You do that?
The skelly replied with a strange answer.
Ya know, I didn't really kill Paps. He has to much DETERMINATION, ya know? I've got him locked up in the shed. Wanna go see 'im?
You nodded your head, even though He couldn't see. Then you realized your mistake.
Sure Sansy. I'd love to go see him.
Great. I've got a special surprise for him when we get there.
Sans grabbed your hand and teleported to The shed.
