Where is the original Rebekah Mikaelson?

Where is the original Rebekah Mikaelson? no pun intended :)

For sure there is something they are not sharing with the media.

She was the only female sibling and important part of the story; producers and creators said time and time again they love Claire and would like to work with her again.

All of us thought she will be back and yes she did in a very cool way in the season 1 final.

Like everybody I thought she is back for good but no; somehow she is not back.

I don't care how the new one is talented; once you get attached to a character which has a 3 year background including TVD, you miss the originals actress

Anybody know the real reason she is not in the originals anymore as we all know initial explanation on her first departure that she wanted to be with her family was *beep*
