Theory/question concerning the end of the Dark Tower quest.
Obviously, this is a spoiler, but hopefully I did the spoiler tag right.
When Roland receives his punishment of reliving his quest for entering the top of the tower and restarts. My theory is that he has drawn a different 3 every time and that his katet changes unless one of the katet becomes so obsessed that they also enter the tower. I think that dying or choosing to leave the quest gives them rest.
"This" time he learned enough of family and responsibility to have altered his own history for the better and has picked up the horn. Perhaps other companions will advance his soul.
Forgive me if that is a common theory, since it seems like an obvious extrapolation.
I also feel like choosing one of the doors on the way up would pull Roland out of the loop. Perhaps allowing him to change his history for the better, like saving Susan.
Has King weighed in on similar theories? I sort of doubt it, as he seems to want to keep unanswered questions unanswered.
Also, I kept trying to see if the horn was mentioned among his possessions in the final book, which would have been a great way to make that final book a true sequel and not a flashback, and would have put an end to speculation on whether a new 3 were drawn every time.
