I liked this episode. It was back to the wraith story and learning a little more about their ways. Teyla is back in the fold, making herself useful with her wraith DNA - it's been a while since she was this useful! Reminds me of the Star Trek TNG:Face of the Enemy episode with Troi as a Romulan. Here are some other thoughts:
Todd - as manipulative as ever! Why do I get an uneasy feeling of him gaining so much power? Anyway it's good to have him on the show.
There were some funny lines, like Todd saying, "I hope they prove as delicious as the farmers who grew them."
Although somewhat predictable, it was an entertaining episode which moved the wraith story along.
