Well, in my brain, there are a couple of different Ennises...
1) Laramie Saga Ennis, who is living happily ever after with Ellery in Laramie
2) "my" Ennis...you can read all about him in Through The Veil Of Time. He's 63, happy with Jack, welcomed a new grandchild into the world on Dec 24th and is mourning the passing of his brother on Feb 20th.
In my story, Ennis and Jack talk about what would have happened if their lives had been true to the story...and Jack tells Ennis, he thinks that he would have found someone else. Ennis would have figured out he is gay and eventually found a new love. I believe that. I don't think Ennis would have lived out his life, alone and miserable, in that trailer. I think the gift that Jack gave him, in his death, is the realization of his capacity for love. That would be the way he would honor Jack's memory.
