agree, Bra'tac should have been there, maybe the actor was not available. I liked the actor/character that was representing the jaffa, he had presence and spoke very good. I also would have preferred the other Tok'ra, Malek. He really made an impression and his evolution, from tok'ra arrogant to someone trustworthy, was coming along pretty good. Alliance and the cure were pretty good episode. The cure really had a nice ending, love that music at the end. Maybe the actor Malek was too expensive, he has a higher profile than the one who represented the tok'ra on death Knell.
I think the writers missed an opportunity with jacob not being trusted by the tok'ra anymore. i would have loved to see more development on that. Make a story about it and show more on how the tok'ra society/people/organization lives/works. It was and should have been a big deal the fact that selmak one their leaders was no longer trusted. And really the reason for Selmak to lose trust was stupid, "You humans dont at like slaves, you are too confident and HARD TO CONTROL", oh really, mr goauld.
