Very good episode!!! It finally gave some insight into the wraith. Not just lifesucking monsters anymore. :)
Koyla is annoying tho, I hope he won't appear anymore. Well after getting killed that is. ;)
Overall, one of the better episodes. Just showing that the wraith will cooperate. After the deal they had with them which failed I lost my trust in them. Not anymore! But perhaps that's just indivually, maybe they will never help humans in general.
It was really nice to see the wraith caring about sheppard and giving him back his lifeforce. That made me smile. :)
Untill next time! See ya!
