When Cole starts thinking about his return to Minneapolis, what is he concerned about? Why is this unusual?

He worried that he won't be able to find the spirit bear once he's home, that once he's back in Minneapolis he'll no longer have the peace he has found.

"But he feared what would happen when he returned to Minneapolis and there was no ancestor rock, no soaking pond, and no totem. Would he syill be able to find the Spirit Bear?"
