The map the pilots are using as Spider-Man looks in through the window shows 3 countries marked up Yugoslavia, Transylvania & Bohemia. Time for a new map folks.
It's strange that after Angelica was kidnapped from the college dance, and Spider-Man and Iceman went all the way to Transylvania to rescue her, they returned to what seems to be the same dance by the time this episode is over. After all, Transylvania is several hours ahead of New York City, add the fact it took several hours to travel there (and back). Realistically, the dance should have been long over. The only possibility is that it was a two-day event. But chances of that was doubtful and even if it was, would the superheroes really wanted to go back there after all that time? Factor in a lack of sleep and a lot of jet lag, and they would have been better off going home to their bedrooms.
I think this episode was also titled "The Bride of Dracula" or at least on ABC Family.
This is also titled "The Bride Of Dracula!" in the episode's title card.
Angelica is hypnotized twice during this episode.
