Elena's birth mother is the central character of "The Vampire Diaries" next week. Titled "Isobel", the May 6 episode sees the character played by Mia Kirshner returning to town and stunning Alaric with her attitude and her demands that he arranges a meeting with Elena.
When mother and daughter finally meet, Isobel refuses to answer most of Elena's questions, but reveals that she will stop at nothing to find the mysterious invention Johnathan Gilbert has been searching for. These attempts include holding someone by the neck and seducing Damon.
In an interview with Buddy TV, Matt Davis who plays Alaric said the re-appearance of Isobel is "one of those moments where you've dedicated your life to a purpose or a cause for a number of years and then you find yourself confronted with it. It's shocking." He added, "I feel, like with all things in life, it never really goes the way you expected."
This would be the last episode before the first season airs the season finale on May 13.
