Young Dracula/Fridge

Fridge Horror

 * Ingrid has spent the time between the second and third series - four years - "making the streets of Stokely run red with blood". Not only is that a fairly horrific number of attacks, but just imagine what things would have like for the rest of the characters, mindwiped by Vlad... if they were anything like Renfield, they wouldn't have been able to quite grasp what was obviously happening around them.
 * Elements of this have been somewhat confirmed...

Fridge Logic

 * In the first episode, Ingrid explains that they had to learn this "stupid language" (English). Makes sense. But why, in the Count's flashback to escaping Transylvania, is everyone speaking it there?
 * Out-of-universe, to make it easier for the viewers to understand as well as figure out what the German was. Can't think of an in-universe reason, though. -- Manga Maniac
 * Maybe it's an Allo Allo thing, where they actually are speaking the appropriate language whilst in Transylvania, but we're hearing it translated?

Fridge Brilliance

 * When Vlad opens the book the pages are blank but Vlad tells the others that their time had come like there was something written on them. But maybe there is writing on them, only Vampires can read it!
 * Or only Vlad can read it. Or they really are blank and Vlad's good side thinks he can use it as a chance to put his plan for vampires and breathers to live together by making out he's the only one who can read it and saying that's what the books says.
 * May have been Jossed. Vlad seems to have confirmed the pages really are blank.
