Um, wow, Canadian promo people. What the f-ck? - Julie Plec on Twitter
Consider the above Tweet from The Vampire Diaries producer to be your spoiler warning, as CTV in Canada has released a new trailer for tomorrow night's "Heart of Darkness" and it reveals at least one major scene.
The sound and the quality in the following video aren't ideal, but you can make out enough and see enough to understand why Plec is less than pleased with all the preview gives away. So watch at your own risk, check out the The CW promo for more of a general tease and, as always, visit TV Fanatic soon after the installment airs for my full review.
It does look to be a doozy.
