Digital Spy talked to Joseph Morgan and Micheal Trevino during Monte Carlo Festival about upcoming season 4, Klaus/Tyler body swap, what it means for Caroline and what do they expect.

Morgan said “I arrived in Alaric’s body, then exited in Tyler’s body, so it was a nice bit of symmetry there from the writers… I’m excited to see how many days off work I can get while he does my job for me!”

“Nobody’s safe,” he said. “At the end of season two I heard Ian [Somerhalder] talking to the show creator Julie Plec about, ‘If I’m not going to be in the show next season, just give me a bit of warning so I can sort my house out’. I thought, ‘If Ian’s worried, then I’m terrified!’ Nobody’s safe.”
Joseph to Michael – “I would imagine first kiss of Klaus/Caroline will be in your body which means I won’t get to join in.”
