Our Vampires Are Different: Technically not a vampire, but looks like one, and is compared to one in more than one occasion as a Shout Out to the original novel, where he is briefly compared to Polidori's Lord Ruthven, one of the earliest examples of suave gentleman vampires in fiction.
I Was Quite a Looker: Flashbacks show the young Vilefort to be a bishonen with a much friendlier expression. It's suggested that being evil along with age gave him his current appearance.
I Want My Beloved to Be Happy: The reason she gives for helping Albert crash Eugenie's wedding. And from the look on her face as they drive away, she's not just messing with him this time.
Andrea Cavalcanti aka Bendetto
Bitch in Sheep's Clothing: He briefly seems to be a highly cultured fop and a decent guy, and continues to put on that persona, but he's really a total psychopath.
Blond Guys are Evil: Oddly enough, since he's an Evil Redhead in the novel, anime!Beauchamp seems to have gotten novel!Andrea's appearance.
