First Nida, now this guy. Tifa really should have been paying better attention to who was around before she went walking through this place. Or asked Cloud to take her around. Really, these responses are normal and she should've expected them. As it is, she lowers her arms to appear less threatening, but her eyes take in the blade still pointed at her as well as the bandage around the guy's head.

"Tifa Lockhart. I'm Cloud's friend," she offers easily. "Sorry for startling you. I should've made more noise when I came in."
