The Vampire Diaries fans were shocked last week when they learned Damon (Ian Somerhalder) had killed Tyler (Michael Trevino), but that's nothing compared to the devastation felt by Stefan (Paul Wesley) and Caroline (Candice King).

As the brother of Tyler's killer and Tyler's ex-girlfriend, Stefan and Caroline react to the news of his death completely differently. In this exclusive video, Stefan, clearly frustrated by his inability to save Tyler or Damon, breaks a glass in anger, to which Caroline reminds him that acting out won't bring Tyler back.

Defeated, Stefan tells Caroline, "I'm at a loss with Damon. I don't know what to do with him anymore."

"Maybe the best thing to do is to mourn Tyler with your friends," Caroline suggests. "We all owe him that."

Will Tyler's murder be the final straw for Stefan and Caroline, who have forgiven Damon for countless indiscretions and murders in the past? You'll have to tune into The Vampire Diaries this Friday (8/7c, the CW) to find out!
