My McKay love grows yet more.
I also liked the fact that, even with 50's technology, the Genii built a computer interface for a Wrath memory card. So seldom are other cutures in the 'Gate universe able to make use of the galaxy(s) the way Earth has.
I think it's kinda cool that Wraith ships seem biological. Neat departure for this universe.
I do think that the one Genii soldier, what was his name?, defeated his own purpose. Saving cocoon-man would have alerted the Wraith, so let's leave some bullets in him? It stops Teyla from exposing you, but... exposes you.
