It's strange for Peeta, too, to be sitting here in front of Daine and asking about her like she's someone else - which she is. He adjusts to it more quickly than he might have otherwise; having been confronted with lookalikes the same day he arrived went a long way toward shaping his adaptability. He got used to talking to people who looked like someone they weren't. This Daine and the other Daine might be the same person, but they're still separate and therefore separate individuals in his mind.

He winces gently when this Daine details her counterpart's troubles. "Ah." That must be terrible for her, in a multitude of ways. At least she's comfortable with the People; other people would be far more traumatized at having small animals spill out of their mouths.

"Is she in the park?" That seems the most likely place for her to go, with animals falling from her mouth. Plenty of safe places to relocate them.
