This episode was somewhat interesting, yet predictable. Tyre, the Satedan wraith worshiper, betrays Ronon once again, but in the end he redeems himself and is the hero of the episode. When Ronon comes to his senses, he will have realized that Tyre and the other Satedans could not have prevented their own fate to become wraith worshipers, and he too may doubt his own strength in the future. Here are some other thoughts:
Commander Woolsey was portrayed as soft and gentle this time. There were funny moments like the door closing on him, talking about his dog, and his expression when carrying Teyla's baby (which brought back images of the holodoc). While this is okay once in a while, I would like to see him assert himself in the future as the leader of Atlantis and not be there as the symbolic IOA commander.
Teyla's decision to rejoin Sheppard's group was pretty obvious, but good.
Ronon stunning someone for spooking him in his surprise birthday party was funny. His expressions during his capture were understandable considering the betrayal, and his recovery reminded me of Teal'c when he was brainwashed by Apophis. I wonder what Ronon would be like if he turned to the dark side later on.
