What does Josh and Jordan’s dad lecture them about? Why do you think he does this?

Dad’s questions are about if Josh has practiced and if Jordan is still with Alexis; Josh’s are about if their family is falling apart, if Dad knows the championship game is tomorrow, and why Dad still calls him Filthy. When Dad asks Josh whether he can see that Dad needs to be here so they can fix the damage done to his heart, Josh replies that he wonders who will fix the damage to his own heart.
