Who's The Jealous One On Tonight's All-New 'Vampire Diaries'?

Elena (Nina Dobrev) gets her flirt on with Liam (Marco James) in this new still from The Vampire Diaries.

Meanwhile, Stefan (Paul Wesley), Matt (Zach Roerig) and Enzo (Michael Malarkey) resort to extreme measures when Tripp (Colin Ferguson) withholds information about his vampire-killing operation, and Caroline (Candice Accola) is in a race against the clock when Sheriff Forbes (Marguerite MacIntyre) gets caught in the middle of a dangerous plan.

Elsewhere, Tyler (Michael Trevino) and Liv (Penelope Mitchell) grow closer, and Damon (Ian Somerhalder) stumbles upon a startling clue that renews his hope.
