Doc?
My question is was Doc gay?
*** Spoilers ***
In his last scene Reese accused him of getting old when he told him he was leaving the trail and he replied to the effect that it wasn't that, but that sometimes you just need something else in your life and that he was going to see his friend. The next we hear Doc has hung himself after killing his friend after his friend had turned on him for no apparent reason. But what if that reason was Doc had told him he had feelings for him. Now this might seem a leap of faith, but this film was made when the last thing you could do was talk about homesexuality openly in a Hollywood movie let alone a Western. I think the writer and director were codedly trying to tell us that indeed Doc was gay.
