Forced to leap to the side, Remus crashed into the doorjamb that led to the hall, tumbling through it and towards Bellatrix's target. Confident from the bangs and flashes emanating from the sitting room, and the whisp of George's monkey having vanished to quickly alert the other Order Members on guard, Remus did not want the kitchen entrance blocked. He wanted a way out, and a way for the Order to get in.
"Confringo!" he shouted, blasting the back door to splinters before training his wand to the witch that advanced upon him. Remus lunged forward, his wand digging at the air with a cry of "Defodio!" as he staggered up to his - thankfully still attached - feet.
