In Blood Wars nothing really has changed - vampires are still fighting werewolves. We’re reminded that Selene had a child and the film begins with the mother explaining the events of the previous films to her daughter. We’re also told that Selene now has a new flame in the form of David ( Theo James, because Scott Speedman from the first two films is presumably now too old) . David’s father Thomas ( Charles Dance) and Selene discover that her child is the target of the villainous Samira ( Laura Pulver from Sherlock) and that her daughter’s blood may be of special value.
