This was really good episode, I think.. I loved the excitement, the way so much was left to be mystery until the end. Also the concept - the way we see trough the episode how the Tok'ra and rebel Jaffa just fall apart. And the way Jacob has prize to pay for his caring and emotions.
But it is not all about the alliance. Somehow it is about Sam too. She is trying to survive all alone in very hostile environment where one of the super soldiers (hate them) is after her. And all the explosions.. all the tension, escaping.. and the end.. very beautiful episode.
