In this episode, Galen stated that if you kill a vampire anyone they turned will change back into a human, but Vlad was still a vampire after killing his dad, who is the one that changed him. If what Galen said was true then Vlad should have been human.
This episode establishes that despite their similarities, Bacchae are indeed distinct from vampires.
Nitpick: When Hercules and his companions arrive at Vlad's castle, Vlad tells him that he has prepared a feast to welcome them. But how did he know when they would arrive? The trip from Greece to Dacia would have taken days, and there was no way to know when they would make it there.
Iolaus: (as he turns into a vampire) Herc, don't give Vlad your blood. Give it to me. (Hercules gives him a dirty look) Sorry, I can't help it.
Hercules: (as the newly transformed Darius tries to bite Galen) You hungry? Try this stake!
Galen: Think you're fast enough to outrun an arrow, stranger?
Hercules: You think you're fast enough to outrun me when I do?

This episode has a character named Galen. The name (if not the character) is a reference to a famous ancient physician. He was one of the first to use cadavers to explore the human internal systems and wrote a manual that was used throughout the ages by physicians. In Greek, 'galen' meant quiet or peaceable.
In Romanian folklore, Strigoi is the word for vampires, as well as any other evil dead spirit, such as ghosts and zombies.
Vlad the Impaler, a.k.a. Vlad III, Prince of Wallachia, a.k.a. Vlad Dracula, was a military commander in Wallachia (present day Romania). He is known for the exceedingly cruel punishments (especially impaling people on stakes) that he imposed during his reign in the 15th century. The title "Dracula" means "Son of Dracul" (his father held the title Vlad Dracul, meaning Vlad the Dragon). Bram Stoker was inspired by this character and used his name for 1897 novel Dracula, which is the source of this episode's storyline.
