Ender's Game Edit
Pinual was mentioned briefly when Ender Wiggin encountered the Giant's Drink in the Mind Game. Major Anderson mentioned that Ender seemed like Pinual because he kept returning to the Giant's Drink, to which Hyrum Graff replied that "Everybody [looked] like Pinual at one time or another. But he's the only one who killed himself." When Ender returned to Earth after Bonzo Madrid's death, Major Imbu mentions that Pinual was the only student in the history of Battle School to have committed suicide.
