I'm going out on a long shot and say that:
should be who we look at.
Exhibit A: Same color Hair.
Exhibit B: He wears glasses so we won't see his eye color!
Exhibit C: Scarring on his face denotes a struggle (flight from his executioner?)
Exhibit D: His name, "The Undead Suitor".
Exhibit E: His title: Sex Symbol (I'd swoon. <3)
Anyway, in all Seriousness, I can't really see it. besides, Vlad is already dead, what's the point in him being a part of the story? and I believe that Louie was actually an innocent bystander, with Edmund being the initial target.
Of course, I could be wrong, we haven't gotten to the end of the manga updates yet.
BTW: I meant no disrespect to The Undead Suitor; I was just adding to the mass
hysteria speculation.
