It seems that now we know that Damon is an Augustine Vampire, we are going to be getting some flashbacks into his past as an Augustine Vampire.
This little tidbit comes from TV Line and from the sounds of it, things weren’t pretty…..

Question: Any Vampire Diaries scoop? —Chery
Ausiello: Now that Damon’s Augustine past has been revealed, get ready for some “really cool flashbacks” in the Dec. 5 episode, teases Ian Somerhalder, who describes the glimpses as “brutal” and “crazy.” They’re so nuts, in fact, that his co-star Nina Dobrev could barely get through them! “It was disgusting,” she says of the scenes. “I’m not good at that kind of stuff and I hated watching it. I’ll probably have to close my eyes when I watch it on TV.”
