The Return (S02E01)

As season two begins, the action picks up on the same night as last season's finale, and Elena arrives home to a nightmare as she discovers the fate of Uncle John and Jeremy. At the hospital, Sheriff Forbes (Marguerite Macintyre) is comforted by Matt, Bonnie and Damon while she waits to hear if her daughter, Caroline, will survive the car accident. After a confusing conversation with Elena about the night's events, Damon is the first to realize that Katherine has returned. Katherine's arrival sends Stefan and Damon on a path to find out what she wants, why she's back and how much of a threat she is to the people they love. (Warner Bros. UK)
