Zoe briefly considered her response, a little angry with herself for being seen so easily. She didn’t know the name of the person who greeted her first. In fact, she didn’t know anyone, save Yako and Allen. Zoe smothered a scowl at Allen's robust greeting, and raised an eyebrow at the energy in which he was downing his shots.
Finally Zoe decided to answer the unknown team-mate with a simple nod. After all, a nod wouldn’t offend anyone, or at least, idealy. Usually Zoe wasn’t so careful about who she pissed off, but right now, in “uncharted waters” so to speak, she wasn’t going to take her chances, team-mate or not.
As it were, Zoe remained standing in the back, although she did lower her hood and then figured it wasn't going to do any harm to ask, "Yes, I'm Zoe. And you are?"
