About 45 minutes in the movie, in the scene where Selene goes to Tanis' exile, she enters and two female vampires attacks her and she leaves them dead. Later on in the movie when Tanis is taking the bodies of the two female vampires so that the werewolves can eat them, one of the vampires he is carrying is holding on to him very tightly around his neck. Is'nt she supposed to be dead?
