As the Gryffindor Common Room was, unfortunately, in a tower, it took nearly half an hour to get to the ground floor. Filch and Professor Sprout were waiting to get the children through to safety. Professor Sprout was visibly fretting, even going so far as to chew on her already stubby nails. Filch was the opposite, terse and snappy. He did seem to be nervous in his own way, though.
