Affliction with Incuritis

- His son is afflicted with a most terrible disease... He doesn't have long, it seems.

In 2025, Greyerl was afflicted with the rare disease Incuritis, likely from a foreign visitor visiting his father. Incuritis has no cure, except a medicine extracted from a Borginian cocoon; however, importing Borginian cocoons to the United States is strictly illegal, and carries the death penalty in Borginia, as changing the process to create the cure even slightly instead allows one to create a highly deadly poison. Greyerl's was the first case of the disease of the disease in the United States. His parents tried a few things to help cure Greyerl, but eventually gave up; by 2029, Rei said that his parents may have even decided to completely give up on him.

- It's just, I've been friends with the Chief Justice since we were students. It pains me to see him going through such a difficult time.

In 2026, Jean's sister, using her father's name, attempted to smuggle a Borginian cocoon from Borginia. However, her plan failed thanks to the interference of Interpol agent Romein LeTouse. LeTouse was fatally shot by one of the smugglers, Daryan Crescend, and Apollo Justice ended up defending the other smuggler, Machi Tobaye, who had been accused of LeTouse's murder. Though Tobaye was eventually acquitted of the murder on July 10, 2026, with Crescend being named the true killer, he was found guilty of smuggling, and so the case ended with both smugglers in prison.

Coincidentally, The Judge visited Greyerl in hospital several times the week of LeTouse's murder, even asking the defense and prosecution to end the trial quickly so he could get to the hospital, and later delaying the trial to visit Greyerl again. In addition, Greyerl's condition apparently worsened considerably the morning of July 10, 2026; his case was reported on in the newspaper that day.

On April 23, 2029, Apollo Justice encountered Rei comforting Jean Greyerl at the hospital, where he had been directed to by pichuis. After stepping outside, Rei explained her tragic backstory to pichuis, including her full name, Shuichi Greyerl. Rei insisted that she would eventually manage to obtain a cure for Jean, saying that she had promised him a happy life.

Three months later, Jean had entered critical condition, having only a few months left to live. Justice encountered Rei crying in his local Subway, where he learned this.

Although Justice did not meet Jean during mvdy's case, he was mentioned a couple of times by Rei, who eventually broke down exclaiming Jean's name before being arrested for Stealphie's murder.
