Klaus will have some new hybrids when The Vampire Diaries returns!   Blake Hood and Alyssa Diaz have been tapped to play his minions, TVGuide.com has learned exclusively.   Hood (90210, The Young and the Restless) and Diaz (The Nine Lives of Chloe King, As the World Turns) will play Dean and Kimberly, respectively. Both hybrids are under Klaus' (Joseph Morgan) control, though Hood will appear in Episode 5, while Diaz will first pop up in Episode 6.   The last we saw of Klaus, he had switched bodies with Tyler (Michael Trevino) so he wouldn't die at the hands of the possessed Alaric (Matt Davis). That should make for some interesting confusion for Caroline (Candice Accola) when the show returns  Thursday, Oct. 11 at 8/7c on The CW.
