Remus was about to break the door down (Sirius had to be home by now, didn't he?) when the door opened. Remus didn't have time to think or act before a fist connected with his face. He managed to move ever so slightly to keep the punch from landing square in his nose. The shot to his jaw, however, came at full force. All Remus could do was sink to his knees, hoping his position on the floor would protect him from any further punches. Remus gingerly opened his mouth, checking to make sure that Sirius hadn't broken anything. The nose was next and while sore, that too didn't seem to be broken. Thankfully.
As best as he could manage from his position at Sirius's feet, Remus looked up and glared. "I'm not watching her every fucking hour of the day! What do you want me to fucking follow her around like some asinine puppy dog waiting for a fucking bone to be thrown in my direction? She was with her fucking mother, you bastard! Are you saying that Andy can't take care of her own daughter!?"
Remus was pissed -- both with Sirius's high and mighty attitude coupled with the way his face ached. He swallowed, tasting the metallic tang of blood. He spat, not caring if he ended up ruining the carpets or not. "Bloody hell, you fucking prat. I care about you both and if you don't fucking realise that you need your goddamned head examined!"
