Aha well possibly but it's a little more personal for Lancer. I'm not sure how Fate savvy you are but he's basically the manifestation of the original Vlad III and he takes it very personally that his reputation was twisted into the basis for the Dracula legend and enough so that he has a power tied into that reputation (which he outright refuses to use while no-one is here to force him).

So yeah. Having so many other Tepes around has been an interesting ride but so far the only one he outright hates is actual Dracula so it's not a lost cause!
