Continuity mistake: The scene in which Sonja is executed in front of Lucian is incredibly different from when the same scene was portrayed in the original movie as a flashback. Obviously they had to reshoot it to account for the new actress portraying Sonja, but not only is the basic setting visibly different, but important details of the scenes have been altered as well. Ex. In the flashback scene in "Underworld", there's a giant crowd of slaves in a cage behind Lucian, and Sonja screams and slowly burns up. In this film, the crowd of slaves is not there, and Sonja instantly burns up without screaming - in fact, she's rather calm and trying to calm down Lucian. You can't argue that Lucian's memory of the events have changed over time, as the "Underworld" movies have made it clear that immortals have impeccable and essentially perfect memory (more-or-less genetic memory) that can even be absorbed if their blood is consumed by vampires.
