The Vampire Diaries The Vampire Diaries

Last week's episode of Vampire Diaries provided a major turning point — Elena learned something's up with Stefan, and now she's determined to find out what it is.

In the Oct. 15 "Lost Girls" episode, a flashback will depict a Civil War-era Stefan, Damon and Katherine, as the Salvatore family history is divulged to Elena and she learns how the brothers' rivalry began.

In the first clip, Elena demands that Stefan start explaining his supernatural behavior. Listing off the vampire behaviors she knows only from fiction, Elena questions how Stefan survives in the sunlight and looks in mirrors, amongst other things, and Stefan debunks common myths about his "people."

In the second clip, Damon demands Stefan return his ring. "What did you Fed-Ex it to Rome? Where is it?" Damon quips. When he doesn't get an answer, Damon turns to threatening Elena. Watch the sexy Salvatore brothers spar below.
