I picked Ennis, he would have been a challenge,which I love.Jack would have been too easy. I tend to prefer things and people I have had to work really hard to get.
I also chose Ennis because in most respects he was honest with Jack.I know he never admitted to himself that he was homosexual.But he was honest with Jack about one really important thing and that was his fidelity.
In the ss at the motel scene Ennis says he has never been with another guy, Jack lies.I know he comes clean at the end,but that is after 20 years.
