Season 2 got off to a great start with this episode, a conclusion to the cliffhanger at the end of season 1 (Within the Serpent's Grasp). SG-1 are captured aboard Klorel's ship as it and Apophis' ship are approaching Earth. Klorel's placed in a sarcophagus by one of his jaffa, who is then ordered to kill SG-1. He goes to follow these orders, and reveals himself as master Bra'tac!
Bra'tac and his two fellow unbelievers help SG-1 lead an assault on the two ships, capturing Klorel and using him as a hostage to gain entrance to Apophis' control deck where they disable the controls, then run off to disable the shields so Klorel's ship will do a lot of damage when the two collide.
Meanwhile on Earth,
major lieutenant-colonel Samuels is back, seemingly for no reason other than to gloat about the new 'goa'uld-buster' missiles he's developed. Said missiles both detonate harmlessly on the goa'uld ships' shields, leaving Samuels embarrassed and sheepish. It's nice to see general Hammond chewing him out, as he's always been a slimy, unlikeable character.
Despite the impending attack, and gen. Hammond wearing his combat fatigues, there's really no sense of tension in the Earth scenes, as there was in There But For the Grace of God. Granted, the attack was fully under way in that episode, and in this one the ships were just sitting there, but it didn't feel like there was any real threat to Earth. There was some tension on the ships, particularly as Daniel was left behind, but that didn't last long. In fact, the team didn't seem too bothered about what they thought was his death, only showing emotion when they were reunited in the SGC. Neither did Daniel seem to care about the fate of the team when he came back through the gate. But, when reuinted, he and Jack do share a big hug, and all's well again - particularly now the Earth is saved from Apophis and Klorel.
Speaking of those two, it's not made clear where they went - they're shown using the ring transporters, but the only place within range was Klorel's ship with the stargate - but you can probably guess that it's Chulak. Which makes you wonder, why does Bra'tac want to go back? He said he already had a hard enough time regaining the goa'uld's trust after the events of Bloodlines, and this time he openly told Klorel about his hatred for the race.
I heard somewhere - maybe a DVD commentary from a later episode, I'm not sure - that originally Skaara/Klorel wasn't in the shot of Apophis escaping through the rings, but after seeing the huge positive fan response for his appearance in Within the Serpent's Grasp they decided to edit him in so he could return in future episodes. Thank goodness they did!
