Cool.
Are "Ennis" and "Roots" in canon? Don't know the proper term... in other words, not AU with E + J as astronauts or something?
Yeah, I don't know all the terms either. AU I know is Alternative Universe, like as you say J&E as astronauts or something, and no these aren't AU.
"Ennis" picks up Ennis's story about 11 years after Jacks death and how he unexpectedly meets someone and falls in love. I like it very much because its believable and possible and because it's good to see Ennis find some happiness at last.
edit update; Well I guess anything that changes the outcome of the original story is AU, such as "Dreaming" and "If I Asked" where Jack and Ennis work things out and pursue the Sweet Life and Canon is whatever fits within the original story s parameters.
"Roots" is the story of Rich and Earl, who they are, how they meet in the late 1800's and commit to pursuing the "sweet life". Of course we know it ends badly for them, but what happens to Rich? I like how the story of Earl and Rich is contextualized in the culture of the American West and how Earls death is an event created by the times and the frustrations of others.
