Sirius is lounging in a way that still manages to make him look graceful and heartbreakingly beautiful. James is lounging in a way that's more of a slump; Remus has just curled up. Peter has sprawled himself out, as per usual, on the floor because between Remus and Sirius on the couch, there is no room for him.
Remus has white bandages winding up his arms; Sirius' wrist is in a sling. Both James and Peter's faces are spectacularly scratched.
It's not odd to see the Marauders lounge, but today the lounging Marauders are receiving strange looks.
