Gah, finally had time to watch Episode 3. I thought the filler part was done pretty well. I didn't think it would have been that good since they probably stuck it in there to just to stretch Zero's bite on Yuki to the end of the episode. And speaking of the bite, it kind of looked like Zero was biting into Yuki's shoulder and not her neck.
Also, for some reason, that creepy vampire kid reminded me of something from LoTR. *shrugs* And was I the only one who laughed when that vampire lady got kicked by Zero? lol
