As previously revealed, Lauren Cohan will play a key role this season on The Vampire Diaries.
The actress will debut on the episode "Rose," as a character by that same name. She'll portray a centuries-old blood sucker with a connection to Katherine - and she won't show up alone.
Entertainment Weekly confirms that Trent Ford and Daniel Gillies (both pictured) will also appear in Mystic Falls next month, taking on the roles of vampires Trevor and Elijah.
"They have deep ties to Katerina Petrova," says producer Julie Plec. "They will be heavily featured in November Sweeps episodes ‘Rose’ and ‘Katerina’."
Ford has appeared on an episode of Smallville and recurred years ago on The West Wing as the boyfriend of the First Daughter; Gilles most recently guest-starred on True Blood and NCIS.
