Buffy shifted a little where she stood, glancing around as if she was keeping an eye on their surroundings, when really she was just trying to keep herself from making too much eye contact. She didn't know how much Faith or Kennedy had revealed to Leah about her, and she wasn't all too comfortable with that.
At the question, Buffy did manage to glance back in the direction of the younger girl. "Oh. No. I'm not really...looking for anything in particular. Just trying to sniff out anything unusual before the sun sets. Just something I do. Try to keep as much trouble away from the Hyperion as possible with the psycho vamps on the loose."
