Personally, I would send them in different directions after the encounter. They get outside, "What the Hell was that?" The alcoholic in the group needs a drink and goes to the nearest bar where an old drunk explains the mystery. The group intellectual searches the library database and the remaining students return to the dorms for the only things college students do more of than drinking. Those people die and it's left to the smart guy and the drunk to save the school. A lot for ten minutes, but it could make a cool montage if you intercut to what they are all doing while the old drunk tells his story.
