The poor woman is clearly terrified, and despite the calming aura of the room, Giles feels all of his instincts kick into high gear. His wariness is justified by the first word out of her mouth, and his demeanor shifts slightly, face tightening and a hint of weariness showing around eyes that have hardened by faint degrees.

Releasing the woman's shoulders, he strides toward the door, grabbing a chair mid-stride and shoving the back under the door handle in one fluid motion.

"Barricade the door," he orders in a brisk, no-nonsense tone, already moving to push a nearby desk over. It registers that he might have spoken more bluntly than he meant to, but he takes the fact that the woman could talk at all after meeting vampires as indication that she is made of tougher stuff than most. Usually it's just high-pitched screaming and unintelligible babble from would-be victims.
