Now that Alaric is no longer a vampire capable of lifting Elena's compulsion, she's resorting to more dangerous methods to remember the love she once felt for Damon.
And Damon is once again practicing the fine art of letting her go.
On The Vampire Diaries Season 6 Episode 7, Elena's attempts to remember Damon were for naught. After telling him to recount their love affair for her, she still couldn't remember anything but the pain he caused and the people he killed.
Until, that is, she tried to walk across the Mystic Falls border to strip away the memories.
