I haven't watched the Vampire diaries in a couple of years, but I find I like this pairing alot.
There's something 'broken' in Klaus. He has so few (if any) redeeming qualities, yet I'm drawn to him and to the budding romance between him and Caroline. I hope that on the new show this season (the one featuring him as the lead) they will either have Caroline appear, or have another such 'love interest' for him. That being said, you captured everything perfectly!
