Crossroads (S04E04)

SG-1 responds to an incoming wormhole with their ally Bra'tac's signal. Instead of Bra'tac, they greet Shan'auc, who tells them that she has come on behalf of Bra'tac. Teal'c goes to Shan'auc and it is immediately evident to all that the two share chemistry and history. Shan'auc claims to have discovered a way to communicate with her symbiote, and it, in turn, has shared memories with her. These memories, she believes, could be the means to defeat the Goa'uld. Shan'auc claims that through their communications, she has convinced her symbiote that the Goa'uld are evil. The symbiote is prepared to tell all it knows to the Tok'ra. Teal'c is skeptical of Shan'auc's claim — until he, himself, shares a memory with his symbiote. The Tok'ra agree that Shan'auc's symbiote is of great value, and they find a willing host for it. Will the symbiote continue to tell its secrets and offer a method to defeat the Goa'uld — or has it cleverly deceived Shan'auc, SG-1 and the Tok'ra into letting it inside their defenses?
