This episode picks up right where the last scene of the previous episode ended -- out on this remote piece of land where Lexie escape the collapsing barn. But this scene for this episode was shot a full two weeks later. The eagle-eyed viewer can tell in the details.
Lexie isn't the first incarnation of Audrey's that has ridden in Vince's classic car. We saw Sarah climb out of the same car over fifty years earlier, in a flashback to 1956 in the Season 3 finale, "Thanks for the Memories."
