Audio problem: At the beginning, when Selene is hunting the Lycan though the subway tunnels, she is pressed against a wall, and she starts to look around the corner. Then suddenly a subway train passes by. Shouldn't we have been able to hear it? (00:08:10)
Audio problem: Near the beginning of the movie, while Selene is looking at the CCTV video from outside the subway station, Kraven enters the room and talks to her. Throughout their conversation, the sound quality of his voice changes as he walks away from where the mic is located (by Selene). (00:17:35)
Answer: Lucian does not die instantly after being shot by the silver nitrate bullet. This also is after he injects himself with Michael's blood. With that said there was a scene where Raze comes back with Amelia's blood (she is an elder). He checks on Lucian while dropping the bag of blood right mext to Lucian. I am absolutely certain he noticed this bag, injected himself with elder blood before he crawled out to stab craven in the leg. Lucian will be back and this was part of the story. When he comes back, they will show the audience in a flashback of Lucian injecting himself.
