I guess not.
The guy that Dylan told to stay in town hated Indians because some time in the past they took his brother in a raid. Dylan rides out of town to stop him before he kills any Indians or is killed by them but is drawn off the trail by the Indian girl. She was a decoy so the Indians could have more time to kill the guy Dylan told to stay in town. Dylan then goes to the sound of a gun shot and finds a dead Indian, White Wolf. The girl tells Dylan the story about White Wolf. Dylan then finds the guy who was supposed to stay in town and he is dying. Just before he died he asks Dylan if he had killed “the Indian”, Dylan said “yes”. Then the dying man said he was glad he killed “the Indian” and then he dies. Then Festus comes up and asks Dylan “did you tell him” & Dylan says “no - but we can bury them together”.
At least that’s the way I understood it.
