Bonnie adjusts to changes on The Other Side this week, while The Vampire Diaries flashes back to the 1960s.

We learn how Maggie died (at the hands of Damon on the night JFK was elected) and see Enzo actually kill himself - sort of, Stefan had his hand on Enzo's heart and Enzo backed away, forcing him to tear it out - in order to cause a riff between the brothers.

Stefan chose not to tell Damon that he killed Enzo.

Markos also revealed his plan: with tons of doppleganger blood, he can end all magic in Mystic Falls, end all vampires and the Travelers can take it over.
