Everything was so ambigous because they didn't want to take down the finale WTF, but we need answers about it. There's something about Tyler's look when Caroline leaves, in their last scene together, at the Lockwood mansion, that makes me reflect a lot. He's staring at her leaving, it's not the first time, actually, he has done it before, but there was something about it that makes me think. Also, why would Tyler want to call Bonnie?
