At the very mention of the name 'Valdemort', Vincent's eyes narrow and his jaw sets firmly.  He nods to himself at the Headmaster's words about new challenges.<br/><br/>Oh, yes.  Yes, indeed.  The Headmaster is<em>quite</em>right about that.  And how kind of the old man not to belabor the obvious!  From a lesser wizard, the subtle kindness would be a stinging rebuke.  From Albus Dumbledore, it is what it is.<br/><br/>Turning to gauge the response of his own house, the Prefect's gaze sweeps along his fellow Slytherin.  Younger students in particular flinch under those steely eyes...and some of the older students, as well.  Satisfied that nobody is going to be bloody stupid right this moment, Vincent turns his attention back to whatever internal matters have personal priority, eating sparingly.
