Jaskier and Daphne
Jaskier couldn't play the piano particularly well, mainly because he'd never really had access to the instrument. So he was impressed when someone was able to play. He thought the woman playing did particularly well. Yes, he was paying attention to other people on stage. Just because he wasn't on stage currently didn't mean he couldn't appreciate other people's efforts.
"I am," he said, with a small smile, as the woman questioned him. "I am glad they put this together." He hadn't realized it was an annual thing. How could he, when he'd just arrived not too long ago?
