He remembers her. Not that he would easily forget such a strange creature--person?--in the first place, but having her run screaming when he first saw her certainly left an impression. He's surprised that she approached him after that, even with the mask put away for now, but doesn't discourage it.

Instead, he calmly watches her approach his table, and slowly nods at her observation.

"The mask was part of a dream--a nightmare." He doesn't need to go into the details of it. And it's no lie. "It serves little purpose here." He takes a sip from his mug of ale, then shrugs, to indicate that's all he has to say on it.
