By asking Cole to think of the rock as his ancestors, Edwin essentially asks Cole to think about other cycles aside from violence that may be a part of his family. It forces Cole to consider what he may have learned from his mom’s choice to finally report Cole’s dad, or to consider his dad as an example of what not to do. Even though Cole doesn’t see the point of the ritual this time, Edwin nevertheless makes it clear that going forward, if Cole wants to improve, he must make the choice to take it seriously.
