A surprise is in store this week on The Vampire Diaries. That much was hinted at in the official CW preview for "Kill or Be Killed."

A peace offering will also be made from Stefan to Mason Lockwood on the episode, as the former tries to make up for the rude, nearly murderous actions of his brother.

What else can fans look forward to on Thursday night? A ravenous Caroline, if the following photos are to be believed. Sort through this gallery of images from the installment and get excited for more Mystic Falls suspense...
