Taylor has to fight her instincts as a new, unidentified presence enters her awareness. They scream at her to tense and whirl, to grab the nearest weapon and launch herself at the unclean thing behind her. They're not particularly concerned about onlookers or academic records. Taylor however, is.
Fortunately, she has some options. She goes out into the parking lot, and tromps up to one of the cars there. In her reflection in the car's back window, she starts fussing with her hair...but really is more interested in scanning behind her, looking for a person that matches the itchy feeling between her shoulderblades.
