Oh, you did it again, you wrote a wonderful Nathan again ;-D
Loved his life and how snarky he could be. And how great a fighter and hunter he became. There's a lot of great humor in this one, even if Nathan's life has been pretty harsh in part. But there's evidence of a lot of good things and a lot of loving as well.
The way Rain made him marry her, that was priceless! And how he reacted to Josiah wanting to be a priest. That threw me by the way, that he's Josiah's father. But their relationship is wonderful.
And the meeting between Chris and Nathan was priceless too, wonderful banter with Chris being the Chris I love and know from the show.
Sooo... Ezra played a small part in Nathan's life as well.... As he did in Buck's. Although with those two it's nothing as involved as he was with Chris. I'm getting a sneaky feeling I'll see him crop up in all the other's lives. And maybe Vin's story will also tell us more about Nathan's relationship with Vin.
