OH MY GOSH. This is an impossible question because so many great things happen in every episode. My gut says "Vampire Katherine," the revelation that she was one, because the last vestiges of my initial expectations for the show died with that, and what the show really is is so much better. But there have been so many great moments, none of them quite as plot-twisting maybe but all adding up to my loving the show a whole lot.
