His sobs are barely differentiable from his incoherent cries now, and he throws himself forward with such force once Regulus pulls away that the heavy base of the chair tips forward dangerously. But no matter how hard he tugs and pulls and strains against the invisible force (will he have scars marring his skin from this night too?), the spell holds firm.

Remus' screams follow Regulus down the hallway, a steady litany of No! and Please! and REGULUS! that carries nearly all the way to Sirius' room.
