When Sukie and Warlow were having sex. Did she really actually bit him. It looked like she had fangs and bit him?

Yes she bit him no she is not a vampire and it is easy to bite through the skin she was doing it to heal her blood loss because warlow fed on her.

no she did not because if she was a vampire they would have noticed it and she would be able to heal herself and bill and eric would not have to heal her
