The most important lesson from this episode is that if you're going to be a vampire, you need to be an Original. All you have to do to cure a werewolf bite is stake yourself and come back to life.
I didn't see that one coming.
The one thing I find disappointing about this (and VD's) treatment of werewolves is that there aren't any, because the budget is too low to hire animal trainers on a regular basis. Both shows have the most discussion of werewolves without showing any actual wolves of any supernatural drama I've seen. Unfortunately, going the Buffy route of a guy in a wolf suit isn't considered an acceptable solution anymore in the age of visual effects, I guess. It would have been nice for Klaus to actually become
a wolf for once when he shredded everyone, but they obviously couldn't afford to do that. In fact, I don't think we've ever
seen Klaus transform, even though he supposedly can, now that he's broken the curse.
Also, I'd rather have more Davina than Amnesia Girl. The latter is boring and superfluous, and I'm still waiting for her to become relevant. We have no reason to care about her crazy witch-hexed cousin, since he was never part of the cast.
