Season 1, Episode 11
With the exception of the car crash that Stefan (Paul Wesley) saved Elena from and her parents died in, Season 1’s episode, “Bloodlines,” marked the first time Elena almost died. The end of the previous episode was perhaps the biggest moment for Elena and Stefan as they consummated their relationship. But moments later, when she finds out about her remarkable resemblance to Katherine, she flees from the house in a panic and hits a mysterious person with her car. Damon (Ian Somerhalder) saves her and then kidnaps her for a road trip to Georgia.
