Note that Kiowa isn't even telling Glass to stop his quest for revenge—he's merely asking him to put it on hold. Glass has no interest in this advice, however.

This is a perfect illustration of U.S.-Indian relations of the frontier.

The only question that remains is who's going to drop the match.
