We know both Ian Somerhalder (Damon Salvatore) and Kat Graham (Bonnie Bennett) will be back for Vampire Diaries Season 6, but Ian is playing coy about his character’s possible demise — revealing to fans at a Brazilian convention one of his chief regrets should he not return to TVD. What is it?

"What I was mostly saddened about is that I didn't spend all this time with Katerina Graham, because she is not only my sister but she's one of the most talented actresses in Hollywood," Ian sweetly said to the enthusiastic fans gathered at a recent convention in this video posted by Entertainmentwise. OK, this melts our hearts a little bit — especially because we think there’s a good chance Ian and Kat will have an opportunity to work together a lot in Season 6 as they are presumably stuck in the same place following the events of the Season 5 finale.

Of course, there is a chance that Bonnie and Damon were separated when they were embraced by that ominous white light in the season-ender, but we think that would be a missed opportunity. For a TV show to survive creatively into its later seasons, it needs to explore new character dynamics — and the relationship between Bonnie and Damon is the perfect opportunity. These two have been friends for the sake of their shared loved ones, but they have never been friends in their own right. How cool would it be to see an unlikely friendship -- or, at least, mutual respect — develop between these two as they struggle to find their way back to the people they love? Who’s with us?!

Did your heart melt at Ian’s kind words? Do you think Damon and Bonnie might become friends in Season 6? Sound off in the comments below!
