"I'm Bay." She's not sure why this guy is talking to her yet, and the confusion is plentiful on her face. He seems harmless enough. If very tall from how much limb he has going on. But she'll shake his hand all the same, a greeting she knows well enough.

"Can I help you with something?" She is aware that being 'new' is obvious about her, but she's hoping there's more to this. If not she'll just take the opportunity to ask him more questions.
