Shiki 3- The show seems interesting, I'm getting into it a lot, but something about it bugs me. I understand them trying to make it scary, but why would they turn the screen black on the guy with the blue hair carrying a backscratcher with him? What do they want people to think? "OMG THE BACK SCRATCHER OF DEATH!?!?!?!?!"

Nope, that's not it. There's something much more ominous afoot.

Read the spoilers if you wish, but you'll just spoil the fun for yourself.

 Tatsumi Spoiler

Tatsumi is a powerful werewolf-vampire hybrid, serving the Kirishiki family. Being part werewolf, he is unaffected by anything a vampire would be vulnerable to (AFAIK). The vampires in Shiki, Tatsumi included, can only enter buildings if they have been invited into them. That's why Tatsumi went evil mode-ish there; it's an indication of what will happen next.

 What happens next

Remember Tatsumi asking if he could bring a "friend" along? That "friend" is none other than Megumi, who will then proceed to feed on Tohru (I think that was his name. The blonde guy with curly hair) because she's jealous that he's so close to Natsuno. Tohru will eventually die on the fourth night of being fed on.
