In The Vampire Diaries Season 3, Episode 22, “The Departed,” we’ll meet pre-tragedy Elena and her adoptive parents, Grayson and Miranda Gilbert. TV Guide has the first look at the pair, who will be played by James MacDonald and Erin Beute. The actors also know how scuba dive, which was important for the scene they filmed earlier this month. “I'm used to being underwater with a tank, but having to act without the tank is completely different,” Nina told TV Guide of the stunt.
The episode will flashback to the night when the Gilbert parents died going over the bridge in their car — and Elena nearly drowned, too. It was Stefan (Paul Wesley) who saved her life, and we’ll get to see that as well. Paul and Nina talked to MTV about prepping for the scene. While she already had her scuba certification, Paul was afraid of water before filming the action.
