After shutting off her humanity following the death of her mother, Caroline gives her friends an unexpected ultimatum. Not knowing how to handle the new Caroline, Stefan’s attempt to intervene sets off a dangerous chain of events, leaving him and Elena in a race against the clock. Meanwhile, after seeking answers from Kai about the prison world, Damon’s world is turned upside when he learns some devastating news about his mother Lily. Elsewhere, Enzo finds himself becoming increasingly intrigued by Sarah Salvatore, and Bonnie begins to struggle with the effects of being back in the real world.

In an attempt to make things right with his brother, Damon offers to have Stefan’s scar magically transferred to him, only to discover that doing so may come with some unexpected consequences. With time running out and Rayna closing in on Stefan, Valerie desperately attempts to reason with Damon before it’s too late.

Elsewhere, after being framed for breaking Rayna out of The Armory, Enzo attempts to clear his name, but not before a violent run-in with Nora forces him to make an upsetting discovery.

Stefan and Damon attend an anger management support group looking for their next victim. Sybil is still alive and teaching a group of high school students who she’ll later use as leverage to get Caroline to locate a historical artifact that can be used against her. Meanwhile, Stefan and Damon continue their commitment to Cade as they test the morals of a young doctor, Tara.
