Tokra II.

The Tok'ra have turned down O'Neill and SG-1's request for an alliance against the Goa'uld because, the people from Earth don't offer them anything in return. Also there is mistrust as none of the team will act as host for Selmak, a Tok'ra whose host is dying.

Dr. Carter comes up with an idea. Her father, Gen. Jacob Carter who is dying of cancer, perhaps he will become a host, then both lives will be saved.
Her father is astounded by all of this, but agrees to go. On there return there is Goa'uld death gliders every where, and the Tok'ra must evacuate this planet. The bonding of two sick beings begins, there is great risk both will die if not enough time is given. Jacob is to weak to move.
