you were seen! by no less then seven muggles. do you have any idea how serious this is? you have risked the exposure of our world. not to mention the damage you inflicted on a whomping willow that has been on these grounds for hundreds of years.
silence! i assure you, were you in slytherin and your fate rested with me, the both of you would be on the train home tonight. as it is --
headmaster, these boys have flouted the decree for the restriction of underage wizardry. as such.
if i might, headmaster.  the others turn, watch snape separate from the shadows.
perhaps potter and his friends were simply in the wrong place at the wrong time.  could snape be defending harry and the others blink. them?
however, the circumstances are suspicious. i, for one, don't recall seeing potter at dinner.
yes, miss granger?
expelliarmus! a dazzling flash of scarlet light bursts forth and blasts lockhart off his feet and into the wall behind.
perhaps it would be prudent to first teach the students to block unfriendly spells, professor.
weasley's wand causes devastation with the simplest spells. we'll be sending potter to the hospital wing in a matchbox. might i suggest someone from my own house. malfoy, perhaps. malfoy and harry eye each other malevolently as they take their places onstage. grudgingly, they bow to each other.
don't move, potter. i'll get rid of it for you.
just the man. a girl has been snatched by the monster, lockhart. your moment has come at last.
weren't you saying just last night that you've known all along where the entrance to the chamber of secrets is?
