That look, too, was one he'd seen on the Careers. Peeta gave her a skeptical look right back, his forehead wrinkling. Though she'd been relatively polite at first, the way she was speaking to him now seemed a bit more telling of her real personality.
"And I've never heard 'Santana' as a name before, so I guess we're one for one on weird names tonight." It wasn't something he'd usually say, but Peeta was okay enough at picking up on social cues -- especially compared to Katniss. Politeness hadn't gotten that far, so he was open to trying a different tactic.
All thoughts about carrying on the pretense of conversation, though, left once Santana spoke again. It could've been a fake-out, but the way she was behaving, previous banter or not, was enough for him to assume something was up. Really up.
"Are you in danger?" Peeta's mind went to the notes, wondering if Santana'd gotten one directly instead of seeing them around town, and then the wind picked up again. Stronger, this time, and he looked instinctively around before looking back at her, glimpsing something shadowy and distant over Santana's shoulder.
