What is the beginning problem

Things begin to change soon for Josh, however. JB gets a girlfriend, and begins spending less and less time with Josh and Chuck. Josh begins to feel lonely, and jealous of JB, leading to anger on the part of Josh. After a failed bet with JB leads to JB accidentally cutting off five of Josh’s dreadlocks, Josh must have his head shaved, and his anger toward JB only increases. At the same time, Chuck’s health takes a precipitous decline, as his lifetime of poor eating habits combined with a genetic predisposition to heart conditions finally catches up to him, causing him to experience numerous symptoms from nosebleeds to coughing fits to mild heart attacks.
