Incensed, Walburga's face was frozen in a twisted mask of rage as her body slammed into the hard floor beneath her.
Sirius just stood there. His wand slipped from his fingers and clattered against the floor; he didn't notice. He didn't notice when Regulus came to his senses enough to leap to his feet and run out the door without so much as a pause. He didn't notice as Remus walked towards him. His face was burning, even though all traces of colour had been leeched away. "You fucking cunt," he whispered down to her fallen, bound body.
The next thing he knew, he was being grabbed by the back of the neck. For a split second, he thought holy fuck, Remus is attacking me. The fraction of time quickly passed as possessive lips latched onto his, and Sirius grabbed onto Lupin's collar and kissed him back, deeply.
