In chapter 17, besides when Edwin refers to when he was banished to the same island him, Garvey, and Cole are on, what are some other insights about Edwin that are referred to by him?

The reader gets the idea that Edwin's wisdom comes as much from experience as it does from elders and thinking about life. He uses metaphors and parable-like stories to get through to Cole. Edwin also speaks from experience whenhe warns Cole about how hard winter will be.
