Tennessee House. Damon douses the living room with gasoline because while Klaus and Stefan don't care about covering their tracks, he does. Before he lights the match though, he hears the floor creak under his feet. He lifts up the rug and finds a trap door to the basement. Opening it, he finds shackles and chains. "Well what do you know? Werewolves." This confused me at first, because certainly the dead women were not werewolves. Well, at least Blondie wasn't, because she was compellable. Sadly-not-a-witch could have been. She'd have no way to fight back unless it was her... time of the month, but if she was a wolf, Klaus would have turned her into one of his hybrids, instead of letting Stefan kill her. But then I remembered that Klaus got the women to admit that Ray Sutton returned to that house, at least once a month -- i.e. full moon time. So, even if neither victim was a werewolf, they must have provided monthly kennel club service, so... never mind. I really didn't understand the purpose of this discovery at first, but I guess it's to tip Damon and Alaric off to Klaus and Stefan's mission, and the progress they're making. Now why Klaus didn't just grab Tyler while he was still in Mystic Falls -- I can't figure that out. He seemed to be pretty all-knowing, and even if he didn't know Tyler was a wolf, he knew there was one in town, because he knew Damon had been bitten. And since Klaus used Jules as the wolfy ingredient in his spell last season, smart money says he knows exactly what Tyler is. For know, I guess I'm just going to have to fanwank that Stefan decided to cover for Tyler and steered Klaus away from him and out of town. Anyhow, Damon drops the match, throws his hands in the air and he and Alaric leave the burning house.
