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.
