the vitabu have really confused me and I know that these guys in The Vampire Diaries are just actors and stuff, but since when has Elena been blonde lol?

Well,the vitabu are really different from the show, In the vitabu Elena is a Blonde and Bonnie's a red head,plus in the onyesha There are some charecters that have never been mentioned in the vitabu and the opposite :)

she's been blonde since forever! the onyesha is based on the very maarufu book series. they've changed a bunch of things in the show, but it just makes it that much better and it's still awesome!
