This week's return of The Vampire Diaries brought us a twist ending: it turns out that Alaric is actually the serial killer. Apparently the Gilbert ring that keeps bringing him back to life is also driving him into a murderer, which he didn't even realize.
Whatever is happening to Alaric, it's going to make him very dangerous. Now that he realizes that he's behind these killings, he's going to get even more violent, as you can see from the preview for the March 22 episode of The Vampire Diaries (watch it here).
In next week's episode, Damon is shocked to see Sage in present-day Mystic Falls and accepts her help in trying to figure out Rebekah's plan. Elena asks Stefan to help her with a friend in hopes that it might bring him closer to his humanity and Abby struggles with her new life as a vampire, while Bonnie and Caroline try to help her. Damon also discovers a new secret weapon that might help them and tells Stefan about it.
Watch a sneak peek below for the March 22 episode of The Vampire Diaries, airing at 8:00 p.m. ET/PT on The CW. You can also browse through photos for the episode here.
