Wow, that's real fucking interesting.
I don't recall any specific moment, though, that had Wes forgiving Gunn. I could be totally wrong on that, though. Cause I don't have the DVD's yet. I hate you all btw. Wes' insanity, however, started after Origin, I believe. I think a lot was forgiven when Illyria arrived, because Wes still had a part of Fred left. It was a perverted view of things, and it got much worse when the possibility arose that the Fred he loved for so many years didn't _really_ love him because her memory was changed. That twisted his already perverted view of Illyria and it drove him to the brink of madness. Him wanting the lie at the end, when he is dying, is so tragic and beautiful in that way.
God I want those DVD's.
