Klaus contacts Chicago witch Gloria to help him find the reasons why his plan isn't working as he expected. Gloria, though able to see glimpses of the puzzle, needs Stefan's help to piece it all together. Damon is pushed to his limits by a new enemy in Mystic Falls with far reaching effects. Even while helping Elena confront her feelings, Caroline tries to cope with her own emotions. Jeremy is left extremely confused after a dramatic and important discovery with one of his ghosts. But it's an unexpected meeting involving Bonnie that will touch everyone's lives.


The Vampire Diaries is based on a novel series penned by L.J. Smith where you are given the insight into the diary of 17-year old Elena Gilbert (Nina Dobrev). Elena and her 15-year-old brother, Jeremy (Steven R. McQueen), live with their Aunt Jenna (Sara Canning). Elena seeks comfort from her familiar social circle – best friend Bonnie (Katerina Graham), frenemy Caroline Forbes (Candice Accola), and former boyfriend Matt Donovan(Zach Roerig, Friday Night Lights).
At Mystic Falls High, Elena and her friends become fixated by a mysterious new student, Stefan Salvatore (Paul Wesley, "Fallen"). Stefan and Damon(Ian Somerhalder, Lost) are vampire brothers – one good, one evil – at war for Elena's soul.

The Vampire Diaries is from Alloy Entertainment and Bonanza Productions Inc in association with Warner Bros. Television and CBS Television Studios.

Previous on The End of the Affair

While in Chicago with Klaus, Stephan runs into a vampire from his past, someone still interested in him after decades. In a flashback to 1920s Chicago, Stefan recalls a troubling chapter in his life. Following a tip, Damon and Elena follow the trail of Stefan and Klaus. Wondering what's happened to Caroline, Tyler asks Sheriff Forbes for help.



Nina wakes up in bed with Damon. They decide they're going to Chicago over the weekend to find Stefan. Elena looks through Stefan's diary to find out more about his past. Damon brings Elena to Stefan's old apartment where she sees the walls covered in names of his past victims.

Meanwhile, Stefan goes to a bar with Klaus in search of a witch named Gloria to find out why he can no longer create hybrids. She says that she needs contact with a witch named Rebecca, who Klaus needs to bring to her. We then see Stefan looking at a photograph of himself and Klaus from the '20s.

Stefan looks for answers. It turns out that Klaus hated Stefan because Stefan was involved with Rebecca, Klaus' little sister. They go to where all of Klaus' dead relatives are and Klaus brings Rebecca back to life. Klaus brings Stefan to his old apartment where Elena was. She hides just before they see her.

Stefan and Klaus return to Gloria's bar and wait for Rebecca. We flash back to when Stefan and Rebecca were hanging out in this bar, deeply in love. Then wooden bullets come flying through the window and Klaus grabs Rebecca to go. Before he leaves, he compels Stefan to forget everything that's happened.

Stefan leaves the bar and runs into Damon and Elena. Elena just wants him to come home. When they hug, Elena tries to sedate him with vervain, but Stefan is quicker than her and escapes. He tells Elena that it's over and that he never wants to see her again.

Caroline's father is trying to "fix" her of her vampire tendencies, so he won't have to kill her. Her mom comes with Tyler in tow to save Caroline. They bring her back home and Caroline and Tyler have a moment together.

Klaus goes back into the warehouse to get Rebecca. She comes out of nowhere and stabs him with a knife, payback for when he killed her. Klaus brings Stefan in as a peace offering and compels Stefan to remember everything. It turns out that they were a really close bunch. They find out that Rebecca is not one of the original vampires Gloria needs and it is a necklace that Gloria gave her, which coincidentally is the necklace Elena has on.
