When Dolohov's curse hit her, Granger collapsed on the spot and I couldn't see her anymore due to the chaos in the street. The only thing that snapped me out of my stupor and spurred me to remove Ginny and Creevey, who Blaise shoved towards me only seconds later, out of harm's way was Ronald Weasley's sudden appearance. He hit Dolohov so badly with an undefinable curse that I wonder if he might be one of today's casualties on the Death Eater side.
