I loved this episode - the emotional bound what they showed between that man and his "daughter", the Wraith. And the reasons he was ready to give up his years and life for her to feed. Many would not understand that.
This episode, really showed us the other side of Wraith - so far they have been always evil. First time we saw someone who tried to be different but as it came out - there is no easy way out and denying will not help it.
All the hunting on the forest, McKay and Carson on their own trying to fight with the Wraith...
