Hints?
It's kind of a toss-up when you wake up in blood.
His eye-lights wandered to his gloved hands. The gloves were stained a darker red than their original color. He felt a cold prickle as marrow dripped down his face.
Papyrus felt his breathing growing faster. He whipped himself around and a sense of calm filled him.
The stranger was standing a good few inches away from him. Papyrus didn't feel as if he was in control of his body as he went over to them.
They slowly stood up, and the pair stood in silence. It was the uncomfortable kind— the kind before a parent scolds a child after their caught doing something reckless.
Papyrus needed to speak. But what was he supposed to say? He didn't even remember what happened! Waves of fury rolled in but no words followed.
He needed to say something. Anything. Just to break the silence before it broke him. So, he did speak.
"WHAT DID YOU DO?" It was too quiet for a shout but too aggressive for a question. The face looking back at him morphed into one of cold exasperation.
"I DID NOT 'DO' ANYTHING!" Papyrus felt himself grow more frustrated with that response.
"THEN WHAT DO YOU WANT FROM ME? AT THIS POINT, EVERYTHING THAT HAS HAPPENED AROUND YOU HAS BEEN NOTHING BUT A NUISANCE, WHETHER YOU CAUSED IT OR NOT. IF THERE IS ACTUALLY SOMETHING YOU NEED TO SHOW ME, YOU NEED TO SAY IT. I CAN'T HELP YOU UNLESS YOU TALK TO ME!" Papyrus's tolerance for these cryptic messages was growing weary.
The stranger looked away from him in contemplation.
"CAN YOU KEEP A SECRET," they rasped. Papyrus nodded.
"THERE IS A ROOM IN THE LAB, CLOSED OFF. IN THAT ROOM, I'VE LEFT MY WORK FROM YEARS GONE BY. LOOK FOR A SMALL RADIO. EVERYTHING YOU NEED TO KNOW IS IN THERE," they spoke quickly.
"ALRIGHT, BUT WHAT ABOUT MY—"
"YOU'RE BROTHER WILL BE FINE. YOU CAN GO HOME." Upon hearing this, Papyrus felt himself calm down. He was about to open his mouth until the stranger vanished.
Papyrus thought about it before letting the thought throw out the window and booked it for Snowdin.
