Helping in the General Village
Remus arrived in the middle of a town in chaos. He'd thought about Apparating straight to the Burrows, but figured there would be enough Weasleys and Potters headed there. They didn't need him. If the village was also in flames, there were going to be innocents, wizard and muggle alike, who didn't have the advantages of a family full of Order members and Aurors to come to the rescue.
Sensing not picking up any threats in the immediate area, he turned his attention to the surrounding houses. A woman struggled to pull two children through a window of a nearby cottage, flames visible behind them. He cast a quick charm to loosen the glass so it would break without cutting them and ran to give assistance.
