The fangs were noticed and already a defense plan was forming in Natasha's mind, though her poker face remained. She looked over the redhead, searching for any signs of familiarity in return. When she found none, she shook her head slightly.
"I'm afraid I can't say the same. I'm Natasha. And you are?"
Perhaps the name would jog her memory where the face hadn't. Or perhaps she did not know this girl who found her familiar. That was an unsettling thought. Natasha preferred to have the upper hand in knowing more about whomever she was interacting with than they did about her.
