Virgil was on campus handling some minor issues regarding a cousin's sudden move out of the dorms when he noticed the sudden burst of undead activity, and while every instinct told him to run for the hills, he has a gun and there are too many kids here for him to do that. If he hadn't been slightly concerned about his safety (that cousin left because she got into a fight with one very nasty fomor in the bowels of the science building) in the first place he might have had an excuse to run.
He'll feel a little better when he finds out that no one can leave, but until then he's going to be out here assessing the situation and picking off these decaying things as they menace the unsuspecting. For example, the one snarling as it rushes towards that nice young lady with the phone. He's a good marksman, he knows how to handle this gun and how to adjust for its recoil, and his first shot takes off the back of its head.
It takes another two as it's rushing towards him to put it down, and he lowers his barely shaking hands as he heads towards Livvie.
"Did you throw that thing?" He asks, with as much politeness as he can muster as he eyes the zombies...attracted by the gunshots, good work, Virgil. "You should probably answer that while we walk. We should find a high vantage point and see what we can do from there-"
He touches Livvie's shoulder lightly as he turns, searching for such a place to make a hasty tactical retreat to. (This is the first time in a while that he's wished that he could have been like his big sister, and not in the sense that he wishes he were a woman.)
