Clear is shocked. Not only because she didn't expect him to acknowledge her, or even necessarily take the sculpture; she kind of expected him to tell her to get off his lawn. Not only because he's speaking Common, to her, and she doesn't understand why. No, it's — at its core, her surprise is just because she isn't the kind of girl people want as a guest at their dinner table.

It leaves her feeling strangely vulnerable and fiercely protective of this old bat's pride. She doesn't know what she's doing, but she remembers finding something that might help on the bracers — so after saying yes, she is, thank you, she fumbles with the device and keys a few words in. The signs she receives in turn, she slowly clumsily offers into his palm, if he'll allow her to. Her grammar is awful, but the meaning comes through: he doesn't need to use Common for her.
