After witnessing the battle, the loss of friends like Garrison, and experiencing the direct dangers of the frontier, Harris decides to leave journalism. He chooses to continue toward Oregon with the apple saplings, actively participating in the settlement rather than just reporting on it.

The Oregon Treaty, signed while Harris is en route to Fort Laramie, resolves the boundary dispute between the U.S. and Britain by establishing the 49th parallel as the border. This shifts the political context, making Polk's covert operation somewhat irrelevant, but does not stop Wayne's immediate threat to Harris or the Arapaho attack, which still pose mortal danger.

Foreshadowing: Harris arrives at Fort Laramie just as the treaty's implications begin to reshape the mission's relevance.
