Maybe Caroline's weakness is that she doesn't have the best of luck in love, but it's not because she's not the perf girlfriend. She just needs to find a guy who matches her obviously superior maturity levels, like Klaus. Or Stefan.
You want a love that consumes you. You want passion and adventure, and even a little danger... I want you to get everything you're looking for. But for right now, I want you to forget that this happened. Can't have people knowing I'm in town yet. Goodnight, Elena.
You are literally the best person I've ever known. And for me to think I could ever change you was giving me way too much credit and you way not enough… you're the good. And I need a little good in my life.
