And the female who got the most attention to detail or actual depth was the freakin' Hogwarts student. Coincidence? I'm not goin any further with that one.
Anyways, a few thoughts. Reinhardt Schneider's opening story does not indicate that he is wielding the VK, and the crimson whip seen in-game did not look the part either. It was changed to look like the legendary whip when fully upgraded in LoD. Considering how this harkens back to the original CV, the Game Boy titles, SCV IV and Dracula's Curse, it seems much more symbolic in terms of inheritence. i.e. Vanquishing the forces of darkness by the hand of a Belmont descendent will bring forth the weapon's full strength. As for the Hunter's Whip used by Nathan Graves, it also appears to be totally separate from the VK. But since his greatest strength lies in the DSS card combinations, the whip quickly becomes a secondary weapon.
I mentioned a theory once some years ago about Reinhardt and Nathan being related based on similarities in their appearance and their whips, and since nothing concrete was ever officially mentioned about their parents' backstories. All we know is Reinhardt's father trained him and was named Mikael, and Nathan's folks allegedly died in battle with Dracula himself. It might have been even possible that Reiny and Nate were one and the same character. I mean it. - Nothing set in stone officially from Grant DaNasty's original Japanese concept? It is open to our interpretation and, maybe, some lucky folks who will get to expand on it in a future game someday. (SIDE NOTE: Why anyone would take anything from Judgment into consideration since it was officially declared non-canon is a mystery) Seriously, with a little thoughtful inventiveness the world of Castlevania, plotholes and all, is a canvas ripe for breathtaking restoration.
By the by, the opening narrations from the N 64 games are the only games to implicitly state that the story takes place in "the province of Wallachia." All other games have been vague at best.
