Watch the Harrowing Promo for The Vampire Diaries Season 6 Episode 12! (VIDEO) 

So remember when Caroline Forbes, desperate to save her mom, ran an experiment on a dying man? She fed him her blood, and hours later, he appeared to be in tip-top condition. He was living it up at the hospital vending machine and practically jumping for joy over his miraculous recovery!

Unfortunately, what Caroline didn’t stick around for was the adverse effect her blood had on his malignant cells; she drove straight home to report the great news to Sheriff Forbes and basically guilt tripped her into drinking some vamp juice, herself.  But according to the promo video for

Season 6 Episode 12, titled “Prayer For the Dying,” Caroline will soon find out the devastating toll her so-called cure has on cancer patients.

“The blood didn’t heal him, it sped up his cancer and killed him!” she exclaims, sounding panicked and worried. Then she breaks our hearts a little by asking, “Why did I feed her that blood?” Clearly, with her mom’s life on the line, regret plays a major theme.

But Stefan doesn’t want Caroline to blame herself. “You took a risk,” he says, trying to console his friend. “You did it out of love.” We then catch a glimpse of a medical team trying to shock poor Liz back to life.

That being said, the evening won’t be full of gloom. There are Delena kisses to look forward to and a nerve-wracking twin merge on the horizon. Take a look, below:

And that’s not all! We’ve got an extra sneak peek video for your enjoyment.

In this one, Liv and Luke are freaking out because their 22nd birthday is only two weeks away and their crazy dad wants them to merge. He’s even visiting them at Whitmore College prior to the celestial-based event to spend some quality time with his children. However, though Luke and Liv are freaking out about this unfortunate ordeal, they’re still holding out hope; they actually think they can persuade their pops to let Kai and Jo participate in the world’s deadliest/most uncomfortable family tradition instead.

That being said, Tyler isn’t letting Liv go so easily. He points out that if the Parker twins (the blond ones) fail to convince Papa Kai and change his mind, then they’ll have to go ahead with the terrible ritual. And in that case? Luke wins, Liv dies, the end.

Check out Liv’s light-hearted response to her beau right below!
