He also suffers from severe narrow angle glaucoma; an acute condition that if untreated can lead to permanent blindness. JoLynn cares for Johnathan alone while her singer/songwriter husband David travels in search of his big break.

During her son"s absence, Johnathan has become more undisciplined than Linda would like. While Mark tries to keep the peace, he is torn between his wife and their daughter-in-law, who he loves deeply.
