mental degradation and alienation from those around him culminate in his chronologically last appearance in the novel, in which his attempts at speech and facial expressions are incomprehensible to others. The origin of Hal's final condition is unclear; possible causes include marijuana withdrawal, a drug obtained by Michael Pemulis, a patch of mold Hal ate as a child, and a mental breakdown from years of training to be a top junior tennis player. Avril Incandenza, née Mondragon, is the domineering mother of the Incandenza children and wife of James. A tall (197 cm, or 6 ft. 5.5 in.), beautiful francophone Quebecer, she becomes a major figure at Enfield Tennis Academy after her husband's suicide and begins, or perhaps continues, a relationship with Charles Tavis, the school's new head, also a Canadian and Avril's either adoptive or half-brother. Her sexual relationships with men are a matter of some speculation/discussion; one with John "No Relation" Wayne is depicted. Avril has phobias about uncleanliness and disease, closed doors, and overhead lighting, and is also described as agoraphobic. She has an obsessive-compulsive need to watch over E.T.A. and her two youngest sons, Hal and Mario, who live at the school; Avril and Orin are no longer in contact. James Incandenza believes that he can connect with his children only through her. Orin believes she runs the family with ingrained manipulation and the illusion of choice. Her family nickname is "the Moms". James Orin Incandenza Jr., Avril's husband and Orin's, Mario's and Hal's father, is an optics expert and filmmaker as well as the founder of Enfield Tennis Academy (though he increasingly leaves E.T.A. business to Charles Tavis). The son of small-time actor James O. Incandenza Sr. (who played "The Man from Glad" in the 1960s), James Jr. created Infinite Jest (also known as "the Entertainment" or "the samizdat"), an enigmatic and fatally seductive film that was his last work. He used Joelle van Dyne, his son Orin's strikingly beautiful girlfriend, in many of his films, including the fatal "Entertainment". He appears in the book mainly either in flashbacks or as a "wraith", having killed himself at the age of 54 by placing his head in a microwave oven. He is an alcoholic who drinks Wild Turkey whiskey. His family nickname is "Himself". Orin also calls him "the Mad Stork" or (once) "the Sad Stork". Mario Incandenza is the Incandenzas' second son, although his biological
