though Jerome is a strong character, he is sometimes emotional. When do we see him becoming emotional

Jerome gets frustrated when things go wrong and he thinks his buddies are being inept. At times Jerome will launch onto a diatribe about things that make him angry. In chapter 8, for example, J talks about on the violence he would like to inflict on landowners who actually do enforce trespassing laws on tourists like himself, since their claim at owning the river is specious in his mind. J can be romantic as well, like when he describes the beauty of a calm night.
