Stargate SG-1: Crossroads

SINOSSI

An old love of Teal'c, Chulak temple priestess Shan'auc, arrives at the SGC saying she can communicate with her symbiont. Teal'c does not believe her, until he tries and sees that it is true. They travel to the Tok'Ra, as Shan'Auc's symbiont needs to blend with a host, but isn't it really still a Goa'uld?
