Vlad is forced to ensure that no one screams at Halloween so that a ‘curse' will be imposed on his family – a curse of normality. If anyone screams the family will remain vampires. But being Halloween, frights and screams abound. Vlad goes out of his way to keep the peace so that the curse will be imposed. Robin on the other hand tries his best to make everyone scream. Jonathan locks Van Helsing up in the caravan – this is a night when his slaying instincts are all over the shop.

Vlad has to sit a vampire exam, his first ever ‘Blood Test'. While he doesn't want to pass because it means that he's one step closer to becoming a vampire, he doesn't want to fail because the Count has said that he will never be able to see his friends again if he does. Robin has a crisis of confidence and turns normal – which means that Vlad is undecided whether to pass the test or not. Jonathan abandons Van Helsing at the castle after Van Helsing breaks his promise to give up slaying.

The Count holds a hunt ball to find a new wife and Van Helsing uses it as an opportunity to infiltrate the castle. Jonathan finds out that vampires really do exist and Vlad has to pull out all the stops to save the Count from Van Helsing. The Branaghs are invited to the ball – not as guests but as the hunt victims. The Count finally discovers that there is a slayer in town and the series ends with a showdown between the Count and Van Helsing.
