The double attack on Justin and Nearly Headless Nick turned what had hitherto been nervousness into real panic. Curiously, it was Nearly Headless Nick's fate that seemed to worry people most.

There was almost a stampede to book seats on the Hogwarts Express so that students could go home for Christmas.
