Stargate SG1 - Divde and Conquer

To be honest upfront, we do not like Divide and Conquer. At all. The zatarc plotline could have been interesting if they’d had more time to develop it. Sadly, we just don’t get the whole Jack/Sam of this episode. Where did it come from? Why is it here? Do you get it? Can you please explain it to us? Why did it have to be Martouf? We like Martouf. Farewell, Freya. It was interesting having you around.
