"Wendell: What can you tell us about Elena's birth mother on The Vampire Diaries?
Turns out that when you discover your birth mother is the same evil woman who blew up the plane that started Fox's "24" the always badass Mia Kirshner things probably aren't gonna be all puppies and roses. Mia will return for next Thursday's, April 29, episode of The Vampire Diaries on the CW, and then she'll be front and center in the explosive May 6 ep, conveniently called "Isobel". In the episode, Isobel will shock her ex-husband Alaric (Matt Davis) when she cruises back into town and demands a meeting with the daughter she fought so hard to keep away, Elena. Based on the slogan in the not-yet-released promo above, Connected to her mother by blood, not love and on what sources tell me, it's not gonna be the prettiest of all mother-daughter reunions. But it is gonna be some awesome TV! In fact, I'm hearing the final episodes of TVD's first season will blow you away. Get ready."
