That's fair enough. But you might benefit from brushing up, all the same. You've been relying on your endowments for too long. If we ever got depowered in the middle of a battle, for whatever reason, I'd like you to be able to hold your own.

[Once again, he draws the knife deep into his forearm and presents the wound.]

It might be a better idea to spar on the beach. I'll remind you how to fight like a man.

[Maybe a tiny bit of teasing in there, since Alucard's childishness invites it.]
