There was one surprising death and one shocking near-suicide on this week's episode of The Vampire Diaries. Read our full review of "Plan B" NOW.

Glancing ahead, how will Damon, Stefan and company deal with these developments on next Thursday's episode? Simple, based on what they say in the following promo: they're gonna kill Katherine.

We have a feeling this won't be as easy as it sounds, but we challenge any fan not to get excited while watching the Salvatores, Jeremy and Alaric prep for battle in this preview for "Masquerade." The installment will center around a costume ball, which means masks and intrigue will abound.

Enjoy the official CW promo:
