Nope. It's not true. Sorry. Try again.

That basically sums up Damon's reaction to the shocker that concluded The Vampire Diaries Season 6 Episode 15, as Bonnie caught a glimpse on camera of Damon and Stefan's mother, somehow still alive and living in a prison world.

In the following sneak peek at The Vampire Diaries Season 6 Episode 16, we see Damon about to dig up the coffin in which his mother is supposedly buried, while Kai tries to hit him with a truth hammer.

"Whatever, whoever is on that tape is not her," Damon insists to his nemesis. "I know my mother. She is not a vampire. She is not in a prison world. She died of consumption in 1858."

We'll soon find out whether or not that's the case, of course. But we somehow doubt it will be.

Elsewhere on tomorrow night's return installment, Bonnie will adjust to life back in present day Mystic Falls, while Caroline will adjust to life without her humanity.

Look for Stefan to try and intervene... and look for this attempt to set off a dangerous chain of events.
