Cryptic Commentary: The Mystic Falls team is the Timberwolves? Why am I just noticing this now? Luka had a great pick up line for Bonnie: "Let's pool our energy together." It was almost as good as Slater's backup drive being named 'Kristen Stewart'. Two ripped out hearts in this episode but not nearly as violent as usual. The back and forth about rescuing Elena and her not wanting to be rescued is getting old though. As usual, Caroline and Tyler were much more interesting.
