Fifth Year
Sirius was rudely awakened by a small shattering in the bathroom.
He scanned the dormitory. James was snoring, on the verge of tumbling from his bed, and Peter was huddled up under the quilt, only his mousey hair visible. However, the curtains were wide open around Remus' bed.
"Remus?" he called.
Sirius' sleepy voice quickly turned into alert concern when he received no reply from the fair-haired boy.
He knocked softly on the door, aware of the other two people asleep in the dormitory, and called Remus' name softly again.
Upon hearing a choked sob, he rattled the door handle, to no avail; the door was locked.
"Open the door, Rem, I gotta piss."
Silence.
"Rem! I really gotta piss, open up!"
"Go away Sirius!" Remus' muffled voice called from the other side of the door.
Sirius sighed, shuffling away from the door.
A few minutes later, and there was a metallic clatter from the bathroom, coupled with a soft gasp of pain.
Sirius returned to his place at the door, tapping on it softly.
"Remus Lupin, open the fucking door."
Still no answer.
"…Please?"
"It's three am Sirius, go the fuck back to bed!" Remus sobbed after a second, his voice catching.
"Fuck that, I'm not leaving 'till you get your arse outta that bathroom."
Sirius slid down the door, pressing his ear to it and listening to Remus sob, in exactly the same position as him on the other side, judging by the sound.
"Don't cry Rem." Sirius murmured, pressing his bruised hand against the wood.
Sirius' heightened dog senses felt a movement of heat over the surface over his palm, just small enough to be Remus' hand.
Sirius didn't move for an hour straight, ignoring the cramping of his legs, the ache of his back muscles and the desperate need for a smoke. And his patience paid off; he heard the door click, and a miserable Remus stepped out a second later.
Sirius stood up, his joints clicking, and pulled Remus' sleeve up easily.
A graphic display of deep wounds formed the crude cartoon-like sketch of a wolf across Remus' forearm.
Sirius pulled the boy into the a hug, grabbing him tightly and burying his head into Remus' hair.
Nothing needed to be said, the hug was all Remus needed.
"Hey, d-didn't you have to piss?"
"Eh. The plant needed watering anyway."
Remus pulled away.
"Y-you pissed on the plant."
"You'd rather I pissed on the bed?"
Remus shook his head, sighing, and watched Sirius' lips curve up into his trademark smirk.
The boy really did have no shame.
