Marcus: I know what you have done, Selene.
Selene: Viktor deserved his fate. And Kraven was no better.
Marcus: Kraven has already reaped the rewards of his own misdeeds. And yes, Viktor deserved his fate, many times over. A terrible business, the slaying of your mortal family. Yet so much effort was spent to conceal this matter from me. What do you suppose Viktor had to hide? Or perhaps it is you Selene, as the last of your wretched family, who has something to hide?
Tanis: You don't scare me, Selene.
Selene: Well, we'll have to work on that.
Answer: This could be a confusion over characters. If I remember rightly, the film opens with a scene set somewhere around 1200AD, showing the three vampire elders, Markus, Viktor and Amelia, leading a war party. Possibly your friend has mistaken Amelia, played by Hungarian actress Zita Görög, for Selene, who doesn't appear in the film until after this lengthy flashback sequence has finished.
