I read the S.S first and after the prologue, I remember thinking that, they came together on paper was an indication that they would come together in other ways also.
I love the marriage idea and I think it fits in well on one level, the only problem I have is that it seems the only way they never really came together, on a permanant basis. They came together as friends, lovers, partners of the soul and heart. Ironically the only record of them being permanently together, is in that shack where Aguirre gave them their instructions.
I do know that when I reached the end of the story, I was sobbing and that line came back to haunt me. They spent a lifetime never doing what Jack so badly desired. Sure they had their illicit fishing trips, but that was it.
The only time I think of them as being forever joined is when we read of, or see the 2 shirts. This is a story and film that still hurts me on almost every level, after all this time. I do not think I will ever be this affected by a story or film ever again.
