Hermione Granger and the Irresponsible Boys

Hermione is a friendless Ravenclaw, but she has too much studying to do to be bothered by that; if Potter and Weasley would study more and rush into suicidal adventures less, then she might get it done; but with incompetent professors letting them by, and Malfoy pushing her to join him in catching them red-handed... well, it would be nice to know they were safe in detention.
