How has the relationship between the father and son changed?
This is what I got from the last stanza.
the father is now the son and the son is the parent.
In "Follower" the person who follows is.
both father and son. but in the last stanza the father is stumbling behind the son. the next to last stanza the boy says "all I ever did was follow"

That is in many ways what happens as people grow old. When young the child depends upon the parent, mimicks the parent, learns from the parent. Then in old age, the parent must depend upon the child, and often the child must look after the parent. This is happening more and more often as people live longer.
