Chris jumped at first then laughs at it and smiles offering the ghosts some food, as he eats some more grapes and other things.  He entertains some of his fellow Gryph's by juggling 16 oranges infront of them and then passing an orange down the table dividing the fruit up evenly.  He watches any of the cute girls at his table and tries to strike up conversations with a few of them, and the students near him.
