Well, Lazlo, sometimes a gang of bandits decides to rob your nunnery—because why not?—and you see what’s happening to your sisters and decide that you’d rather throw yourself out of the window than allow the raiders to come any closer to you—because why not?—and a vampire passing by spots you in your last moments and decides to suck you dry—because why not?—and then you wake up in the middle of the night, and for some reason, you’re a damn vampire, too.
