Much to her surprise, Snape was there. He didn’t seem surprised to see her, like he was expecting her to show up, though he did narrow his eyes at her. It made her suspect that he somehow saw through her glamour, but he didn’t seem inclined to say anything. Instead, he sighed and extended his arm towards her.
