When she first appeared in Season 1, we knew she not only turned both Salvatores, but was behind their centuries-long rift all because they loved the same girl. She was manipulative, killed and turned our girl Caroline, and continued to do horrible, horrible things. But we started to like her sass and humor, and she livened up the show. When she became human again, which was a large part of the current Season 5, we felt bad for her! C'mon, the girl caught her first cold in, like, 500 years. More importantly, she was truly vulnerable for the first time. Yes, she cheated death by harming Elena in the process, but when she finally really died, we were bummed and immediately felt her absence. Although she's currently in "Hell," there's always hope that maybe, just maybe, she'll come back to stir the pot some more.
