Kat Graham, Ian Somerhalder

How will Damon react to the death of his brother? By threatening Bonnie!

On The Vampire Diaries' penultimate episode, Stefan (Paul Wesley) was shockingly killed in the final minutes by the Traveler inhabiting Tyler's body. And with the Other Side disintegrating, Stefan could potentially go away forever. Now Damon (Ian Somerhalder) is downright pissed, and he is taking it out on the wrong person considering Bonnie (Kat Graham) is their biggest hope to figuring out a way to bring Stefan back.

"You said you had a plan, Bonnie," Damon yells in the exclusive first look at the episode below. "You need motivation. Because if the Other Side goes away everyone we know there, including you, goes away with it."
