'The Vampire Diaries' recap: 'Down the Rabbit Hole'

I wanted to start off this recap by wishing everyone a happy Vd, as in Valentine's Day, but having seen tonight's episode, that seems horribly inappropriate. I might as well bring cookies to a funeral or hand out flowers at gastric bypass. This is not exactly a warm and fuzzy episode, even though sparks do fly between Caroline and Tyler. But I'm not even sure that's a good thing, at least in tonight's context. Unraveling this episode takes some doing, as quite a bit happens and the intrigue surrounding the hunt for Silas has more layers than your standard Awesome Blossom.
