How could Dracula have a daughter?
This was never really explained in the movie, but at one point Countess "Zaleska" reminisces with Sandor about remembering her mother singing to her in her cradle and the "fluttering of wings", while Sandor reminds her it was the wings of bats, etc. So...I guess she was a vampire baby? This brings up all sorts of silly scenarios like, do vampires reproduce sexually? If a baby is born a vampire at what point do they "grow up" and stop aging? And what about the three "wives" that Dracula has in the first film, was Gloria Holden supposedly lurking around the castle too?
I like the movie but this idea seems a little too far-fetched to me.
