The Show

The Vampire Diaries is an American tv show based on the novels of the same name by L. J. Smith. It was developed for television by Kevin Williamson and Julie Plec.
The Vampire Diaries premiered in the CW on September 2nd 2009 and it's actually on its second season.

The Vampire Diaries follows the life of Elena Gilbert (Nina Dobrev), who falls for the century-old vampire named Stefan Salvatore (Paul Wesley). Their lives grow more and more complicated as Stefan's vicious brother Damon (Ian Somerhalder) returns to town with a vendetta against his brother. The series is set in the fictional town of Mystic Falls, Virginia, a town charged with supernatural history. Other storylines revolve around the other inhabitants of the town, most notably Elena's younger brother Jeremy (Steven R. McQueen), Elena's friend Bonnie Bennett (Katerina Graham), who discovers that she is a witch, and their insecure friend Caroline Forbes (Candice Accola).

Season 1:

The first part of the season mainly focuses on the introduction of the vampires, specifically the lives of the two vampire brothers Stefan and Damon Salvatore who, after a long period of absence return to their birth town, Stefan wanting to be the first to conquer the heart of Elena, and Damon to revive his long-lost love Katherine, Elena's doppleganger trapped in a tomb. It also dealt with Victoria "Vicki" Donovan's transformation into a vampire and her death. We then later meet Anna, a vampire who had come to town around the Night of the Comet, who is planning to open the tomb to save her mother, Pearl, but accidentally frees the other "tomb vampires" as well. The second part of the season introduces the newly released tomb vampires, among which isn't Katherine. They end up meeting up with Pearl and Anna, who are housing all the tomb vampires to "take back" their town. We also meet John Gilbert, Elena's biological father who is planning on using the Gilbert device to destroy all the "tomb vampires". The season concludes with the celebration of the town's founder's day which ends the battle of the "tomb vampires" and greets the final return of Katherine.

2x09: Katerina

The episode begins in Bulgaria in 1490 and shows Katherine, surrounded by her family, giving birth to a baby girl. She asks to hold the baby but her father says that Katherine has shamed their family enough and takes the baby away, leaving Katherine sobbing. Elena skips school and goes to the tomb, where she offers Katherine a bottle of blood in exchange for the truth about the doppelgängers and the Petrova curse. Katherine reveals that she was kicked out of Bulgaria and fled to England; she assimilated into English society, where Elijah and Trevor found her. They recognized her as a Petrova dopplegänger and Elijah tried to kill her, but Trevor- who had fallen in love with her-helped her escape. She became a vampire to escape Klaus and incriminated Trevor and Rose in the process, thus causing Elijah and the originals to hunt them for the next five hundred years. A dopplegänger from the Petrova line can be used to break the curse. Elena, as Katherine's descendant, is the current Petrova dopplegänger.

She hoped that in exchange, Klaus would spare her life. Stefan finds Elena talking to Katherine and tells her not to believe anything Katherine says, saying that Katherine is telling lies to free herself from the tomb.
