A lot of fans have been waiting for Delena reunion although that means they're going to say goodbye to Bonnie Bennett.

However, there might be something standing in the way of Elena and Damon reunion. It has nothing to do with "The Vampire Diaries" story in general, but the former lovers Nina Dobrev and Ian Somerhalder reportedly involve in a quarrel on set.
