"When Elena and Katherine have the same dream that Stefan is in danger and desperately needs their help, they convince Damon to help them find Stefan. However, their plans are thwarted by a mysterious young woman named Tessa (guest star Janina Gavankar) who seems to know everything about Stefan's history. In flashbacks to a distant time and place, Tessa reveals the shocking secrets in her past and what she has planned for the future. She also has a disturbing message for Damon about his own future. Silas (Paul Wesley) forces an unwilling accomplice to help him search for Katherine, leading to a confusing and life-threatening situation for Matt.

"You thanked him by biting off his head," Tessa says to Stefan.
Meanwhile, Damon is still jealous of Stefan and Elena reveals that she had a dream about him. She tells Damon, "It was more than just a pit in my stomach this time though. It was real. It was like I was there with him."
