As I was rereading Summer Knight and then Death Masks, something struck me as a bit off. Okay, so ortega rolls up on harry, talking all this duel to the death stuff, right? And Harry is tripping out internally, because Ortega is a bad ass. But just in the previous book, Harry's faced down two insanely powerful chicks who could vaporize the most powerful wizard with a backward glance, along with two utterly nutso Queens of the Sidhe, a psycho-sexy Lady of the Sidhe, as well as various assorted raging centuars, elven warlords and a chlorofiend...er...plant monster.
And prior to that, he summoned forth an army of vengeful dead to skullfuck the last member of the Red Court to get all up in his grill.
Plus, In Deathmasks, he faced down a group of fallen angels who can drop plague curses on a mo-fo, and can't die without assistance from a holy sword.
Is a single vampire lord really gonna make him nervous after all of that?
I'm not saying he wouldn't take the threat seriously. It just seems like he's been up against heavier black hats, often alone, and has survived to tell the tale.
"You must be proud, bold, pleasant, resolute,
And now and then stab, as occasion serves."
