Though Bonnie may be ethereal now that she's a ghost on The Vampire Diaries, it doesn't mean Kat Graham's role on the show is less substantial. In fact, as she told reporters at the 2013 San Diego Comic-Con, she was already back filming... and Bonnie the ghost gets a little bloody! How or why that happens, she didn't say. Still, her fans will be revealed to hear that Bonnie will be included on the action. They were pretty upset after Kat's character died in the Season 4 finale, threatening to boycott the show. Don't worry, guys! As long as we have Jeremy (Steven R. McQueen), we can still "see" Bonnie!
