I expected Todd to have some agenda of his own but I didn't expect him to kill the Primary. I thought that there would be some power struggle where Teyla would have to prove her loyalty to the Primary by ordering her underlings to kill the team, I didn't expect Teyla to become the Queen of the Alliance! O.o
It's too bad that the show didn't go there, that they didn't keep Teyla as the Queen of the Alliance and made that a season arc. That would have been awesome.
I see people quibble about how fast Teyla's change and recovery went but a) it's sci-fi and b) they had Todd's help, after all.
Very, very interesting and some great scenes with Teyla and Sheppard! There isn't enough of them :)
