Damon is about to learn that his mother was a ripper, and when he does he will be looking for Lily in a 1903 time prison. With the help of Bonnie and Kai, the older Salvator brother will try to save his mother. Elena will also be there. Unfortunately, he won't be all that pleased to know that Lily is not the same mother he grew up with. Stefan will not get the chance to help out in Stefan's bold move since he is too busy with Caroline, who apparently has a plan for the former. However, it will backfire and things are going to get extra complicated and messy from there. Watch 'Vampire Diaries' season 6 episode 17 online using the free online stream link at the bottom.

Actress Annie Wersching, who plays Damon's mom Lily, recently talked to TV Guide about her returning character. "She [is] the most intense vampire you can find in the world of Mystic Falls," she said. "Not only is she not the mother they remember, but it's hard for her to even remember that mother she was. All three of them have quite a journey to go through in order to get back to a mother-son bonding scenario."
