Those questions are addressed in the new preview for this week's Vampire Diaries episode. The video begins with a clip of Damon asking Alaric if he's with "the sexy psycho doctor." Alaric just hangs up, but he is. He tells Meredith that Damon's "a little judgmental" when she asks if he still thinks she's the killer. That's putting it lightly, but really, Damon has a point. Just because she came clean about using vampire blood to help her patients doesn't mean she's not hiding something else—like killing people, too. After all, it was her ex who ended up dead soon after calling her crazy. Nina Dobrev explains that no one has come forward taking responsibility for these deaths, which is strange for this town. Who's staking and stabbing people using their weapons?
Meanwhile, Bonnie and Abby are going to be meeting with Esther, who calls them "allies," and even though she's planning to kill all her children just to kill Klaus, it's hard to not wonder if she's hiding something from Elena (and possibly Finn, who's helping her). It can't be that easy to get rid of Klaus, can it?
