I was curious as to the nature of the bat that bit Barnabas in 1795 and turned him into a vampire.  I know that it was summoned by Angelique, but was curious to know if anyone had any insights into the bat's true nature.  Was it a demon, a vampire in bat form, etc.  I know that a similar bat was summoned to bite Barnabas in the Leviathan episodes.  I also noted that, in the 1991 series, the bat appears as a vampire Josette before assuming bat form.  Any ideas?
