In the movie The Revenant, using Henry's corpse as decoy, Glass ambushes Fitzgerald. He chases him into the woods and they engage in a bloody fight beside a river.
Glass is about to kill Fitzgerald, but remembers Hikuc's words and pushes him downstream into the hands of the Arikara. The chief, accompanied by Powaqa, scalps and kills Fitzgerald, but spares Glass. After completing his revenge, Glass retreats into the forest and experiences another flashback of his deceased wife after the death of Fitzgerald by the Arikara.
In the entire movie Glass is hunted by the Arikara but why do they spare Glass at the end?
