Ron's stomach sank. "What do you mean, it's -" His eyes flicked over to the door, their only means of escape, and he straightened as he sucked in a breath and snapped his wand to the side to aim at the doorway. On the stairs, just past the threshold, were at least three men, whose purpose he could guess. Their way out was blocked, the window was too high to jump - he wasn't going to stand around and wait to see what they had planned, not when Lovegood wasn't going to tell them anything useful anyway. He aimed at the closest one and shouted "Stupefy!" - knowing it was too late unless Harry and Hermione were already on the other two, or one of them had a much better plan.
