Hermione lets herself be dragged forward. She's experiencing slight qualms, but they're only the qualms of anyone who's been talked into entering a building with a host of strangers late at night. She deals with them through logic as always. Her phone is with her, of course, so she can call the police if necessary. The Sainsbury's is still open if she needs somewhere to flee quickly to, with bright lights, people, and CCTV. They can't do anything to her in there. She just needs to be alert but not paranoid. And keep an eye on the time, of course. Four hours left until her date with a demon tonight.
