Surprise, agenda welding family members has been the twist of choice for The Vampire Diaries as of late, and Elena's biologicals, John and Isobel, are just the first. According to The TV Addict Bonnie~Katerina Graham is next in line for a family reunion and Bonnie's witchy relative may be in Mystic Falls as I type. In true TVD style the new arrival has their own agenda and is said to have a sordid past with Katherine.
Who does that sound like to you? My guess, and it's only speculation, is Lucy~Natashia Williamson. If you remember in "Masquerade", Lucy promised Bonnie that she'd see her again. What are your thoughts on this new piece of spoilery goodness?
