This week Claudia Black makes an appearance on Stargate SG-1 to warn Lt. Col. Mitchell (Ben Browder) and the SGC that the Ori are preparing a massive attack on Earth and invasion of the entire Milky Way Galaxy.

Black will reprise her role as the scheming Vala, a former Goa’uld host and con artist who finds herself unbearably attracted to Dr. Daniel Jackson (Michael Shanks).

Claudia will be joining the SG-1 Team as a regular cast member beginning next year on the unprecedented 10th Season of Stargate SG-1.

Actor Michael Ironside will also be starring in this episode entitled “Crusade.”
