Remus sits in a dark room with his arms clasped around his knees and thinks of Sirius.
(He can't help it.)
He knows Sirius was a traitor in the end, knows he's locked away in Azkaban, knows he's never coming back.
(But all his other friends are dead, so who else is he supposed to think about?)
He doesn't think of Sirius quite as often anymore. It's only when the moon is full, only when he's sitting up in the middle of the night with the shades drawn because he can't sleep.
(It's only when he's desperate.)
Because Peter was his friend and James was his brother but Sirius, Sirius was his drug, Sirius was his intoxication, Sirius is the worst thing he's ever tried and the best thing he's ever lost, and Sirius is never. Coming. Back.
(And Remus doesn't even want him to. Not really.)
Trembling, he rises from his fetal position and moves to the window. He gently pulls apart the curtains and presses a hand - paw - against the pane of glass.
The moon stares back at him, and Remus searches with lupine eyes, but he doesn't see a face among the craters.
(He only sees bleakness.)
