The words that had been exchanged between he and Sirius were worrying; Peter had been upset, angry, with Sirius, but he never wanted the other man to go and do something stupid!
Peter had no idea just what he planned on doing, however it seemed far from good and he had left quickly, leaving his book open, the charmed object that allowed them to converse through different places, atop his bed.
What the hell did he mean by it all, 'end it'? No one wanted Sirius to do such a thing, no matter how angry they might be at him. It had Peter shaking his head, as he left the Dormitory, and headed deeper into the castle.
Empty classrooms were looked into, windows out of, towards the forest and their favorite spots. Old cupboards, and halls.
Peter saw no trace of Sirius, and so he continued to look.
It was just a last ditch effort, as the seconds had drawn out into long minutes, that Peter headed down the stone steps, into the dungeon. Trying every door he came across.
Why did he go there? It was all because of the strange ways Sirius behaved, acting as if he believed in all the Purest nonsense that the Slytherin's spewed. The dungeons were their hangouts and--
One door refused to open. It was locked. Peter pressed his ear to it, and then began to jerk against the nob, belatedly remembering his wand, which he pulled out, quickly taping the latch and murmuring "Alohomora".
When the lock clicked, Peter hurriedly pulled the door open. He paled considerably at the sight before him, stomach churning. "Sirius!"
He moved forward, hitting his friend's hand and knocking his wand away. Blood!
Oh god, blood was everywhere.
It was a wonder he did not get sick right away. Instead, he pulled his robe off, grabbing hold of Sirius' arm, trying to push the dark fabric to it. Apply, hold... he just wanted to stop the blood a little, to hide it until he could get him to the hospital wing.
"What is wrong with you, prat!?" He demanded, louder then he had ever spoken to Sirius. "Why would you do this!"
