Directed by: David S. Goyer

Hannibal King: She's dowloading playlists. You know, rap hip hop, what the kids are into nowadays. Me? I'm more of a David Hasselhoff fan.
Dr. Vance: How about the President? Do you know who's in the White House right now?
Blade: An asshole.
Hannibal King: Welcome to the honeycomb hideout.
Blade: How do you bank roll this operation?
Hannibal King: I date a lot of older men.
Factual error: When Blade notices the piece of Dracula's armour in the Nightstalkers' headquarters he's shown an image of what the full armour looks like. It'd be impossible to extrapolate a full suit of armour from such a small piece.
Trivia: Wesley Snipes was reportedly unhappy with the script, and caused difficulty on set. He allegedly often refused to leave his trailer, mistreated the cast and crew and became violent at least once. He also refused to film many scenes, forcing director David Goyer to use creative means to add Snipes into them. (Eg. Goyer used body-doubles, CGI and stock footage to add Snipes in several scenes.) Other actors were given much of Snipes' dialogue because he refused to film so many sequences.
Answer: It's possible that he followed one of them back to the base. This is feasible since they wouldn't be able to tell that he was following them because of his shape-shifting abilities.
