"Sorry, Creevy," she apologised loud enough for him to hear over the racket the Caterwaul charm was making and the driving rain and howling wind, and then Ron waved a hand at her to hurry up, and Hermione was running in his wake, wand at the ready. Creevy was by her side as their feet slipped and slid over the cobblestones, Cho flanking her on her left and Neville taking the rear. Hermione tossed her hood back to free up her peripheral vision, and when she caught sight of a front door opening as they ran past, she flung a stunner at the figure silhouetted in the doorway. If that was a Death Eater, they were disabled, and if it was an innocent civilian, they were probably safer stunned on the ground – out of reach of stray curses and hexes and the like.
