Penny slowed her walk and turned to look at him fully. She would take his bait. "What kind of evidence?" she looking up into his grey-blue eyes, wondering if there was some geeky-drugged air she was breathing that was making her think that his eyes were kind of nice, especially accentuated by the pointy eyebrow makeup.
