It would seem ONE TREE HILL fans can safely assume Lindsay wasn’t the one whom Lucas invited to Vegas in the show’s season finale. Michaela McManus, who played the Lucas-jilting editor last season, has just signed on to play the new assistant district attorney on LAW & ORDER: SPECIAL VICTIMS UNIT, replacing Diane Neal (who played Casey Novak). Hmmm… could NBC and SVU making a desperate (and rather transparent) bid to grab a younger audience?
