Hey look, an update! Sorry this took so long, I wrote half the chapter down then lost the flashdrive I saved it too because I'm smart

Papyrus wasn't sure how he had ended up sitting with his back up against the door to Undyne's house. She wasn't even home yet but he didn't know where else to go. He wasn't really friends with anybody else. He couldn't really remember the walk here either, he knew that his thoughts had been a whirlwind of anger and a jumble of other emotions he couldn't quite put a pin in, but anything about the scenery was lost on him.

Papyrus glanced over his left hand, which was resting on his knee, and it twitched as he recalled the exact moment he had summoned a bone in that hand to attack Sans. It hadn't been enough to really hurt him but Papyrus was sure that the emotional pain was worse than the mark he had left on his face. Papyrus winced at the thought and turned to look at the ground instead.

He had hurt Sans.

"Papyrus?" He looked up when he heard Undyne's voice, watching as she removed her helmet to look at him properly. She was frowning, her brow creasing in concern as she looked him up and down before locking her gaze with his. "Training is tomorrow, what are you-Pap? What's wrong?" Undyne dropped her helmet and went over, Papyrus gritting his teeth as he felt another sob threatening to make itself known. "Hey, uh, come on in. I'll make us some tea and you can tell me if someone needs a visit from the Captain, okay?"

"O-Okay," Papyrus murmured as Undyne pulled him to his feet and opened the door to her house, letting Papyrus go in while she grabbed her helmet off the ground. Papyrus stood a few feet from the doorway for a moment, his thoughts spacing out for a moment. He felt a clawed hand gently grab his wrist and lead him over to the table. Next thing he knew a mug of tea was being set down in front of him. "Thank you."

"Yeah, sure thing," Undyne said in an uncharacteristically gentle voice as she sat across from him with her own tea. "Now, you wanna tell me why you look so heartbroken?" Papyrus considered what to tell her, knowing the whole truth sounded really bad and so far fetched...he sighed, staring down at his tea.

"Sans...kept a secret from me, a really, really big secret too. And it, kinda involves and effects me, and...and I dont know what to think. Some of its really bad, Undyne, and I dont know why he didn't just tell me," Papyrus spoke slowly, trying not to cry in front of his hero. There was silence for a moment as Papyrus found himself tapping a phalange against his mug.

"Well." Papyrus looked up as the other spoke, looking thoughtful as she took a quick sip of her tea. "I dont know Sans very well, and we dont exactly get along, but if there's one thing I know about the guy it's that he loves you a lot, Papyrus. Like, he'd probably cut his own hand off if it'd somehow made you happy. So, if he was keeping something a secret, I'm sure he was doing it because he was trying to protect you or keep you happy, somehow."

"Yeah, he would," Papyrus said slowly, thinking about it. Sans did say he had done it to protect Papyrus. He gripped his mug tighter. "I...I hurt him." Undyne's eyebrows shot up. "I got real angry and, hit him with a bone. H-He didn't look physically harmed but, I know I really hurt him doing that."

"You should go talk to him, Papyrus. I really think it would the best course of action." Papyrus looked up at the hurried tone Undyne was using and saw that she looked oddly worried. "Before he does something stupid." Papyrus felt his soul go cold at the tone she used.

Oh no.

"Yes, yes I will. Thank you, Undyne!" Papyrus shot up and bolted from the house, hurrying straight for Snowdin as fast as his lanky legs could take him. How could he have been so stupid? Of course Sans would take it as rejection or something of that sort and Papyrus had just left him there to suffer! What kind of brother was he to do that? "Hang on, Sans, I'm coming!" Papyrus didn't pay any heed to the confused looks he got as he ran passed everyone, it didn't matter what they thought. All that mattered was that Sans was okay.

Please, please let him be okay.

The brisk cold of Snowdin hit Papyrus like a friendly welcome, an assurance that he was almost there. He passed their shed and pulled out the keys in his pocket for their house. The keys seemed like they were fighting his hold as he fumbled with them, but finally he managed to slip them into the lock and turn them the proper direction. He let himself in and tossed them onto the table as he swung the door shut.

"Sans?!" he called when he saw no sign of him. His eyes instantly darted to the others bed room door and he bolted up the stairs. He knocked on the door roughly. No answer. "Sans?!" Still no response. Papyrus took two steps back before throwing himself at the door, the wood easily falling free under his strength. "Sans? SANS!" Papyrus bolted over to the skeleton laying awkwardly on the floor, unconscious. Papyrus picked him up and winced at how cold he was, feeling his soul clench as he spotted the marks on his brother's arm. "Oh...oh Sans I'm so sorry." He gently put his hands over the marks and watched as they glowed, healing magic seeping into the others bones.

How could he have been so stupid?

And that's a wrap!
