Containment’s Kristen Gutoskie and Christina Moses will be staying in the CW fold, joining the casts of The Vampire Diaries and The Originals, respectively, in recurring roles.

Gutoskie will play Seline on the upcoming eighth season of The Vampire Diaries. Seline is described as a warm, nurturing nanny of two young kids by day, and a small-town girl trying to find her place in a dangerous world by night. Bonded to her new “family” in ways she can’t explain, Seline will fight desperately to protect the ones she loves.

Moses has joined Season 4 of drama The Originals as Keelin, a smart, strong resourceful ER doctor – and the last living werewolf of her line. Keelin is openly bisexual, warm and unguarded by nature; but after the rest of her family was hunted to extinction, she went into hiding and since then she’s deliberately avoided getting too close to anyone. She lives in fear of being discovered by the wrong people and has no idea that she’s currently on a collision course with the Mikaelsons.

Gutoskie plays Katie Frank in Containment, which was not renewed for a second season and airs its series finale on July 19. She previously had a series regular role on Beaver Falls and recurred on Republic of Doyle. She’s repped by Don Buchwald & Associates, Alchemy Entertainment and Premier Artists’ Management in Canada.

Moses, who plays Jana Mayfield in Containment, recently wrapped guest leads on Rosewood and Roadies, and has a lead role in indie How We Met. She’s repped by Dede Binder at Defining Artists and Eric Nelson at Nelson Management.
