Later in the season, Pratt discovered a church holding an illegal prescription drugs exchange program between church members. Pratt tried to reason with the pastor to seek better alternatives. With no compromise being met, he decided to take part in the program to make it safer by donating some narcotics from the ER. However, when a member of the church died from the result of the drug exchange, an investigation was conducted by police and social workers. Pratt soon admitted to his chief, Dr. Kovač, that he was solely involved in the scheme, preventing any repercussions on the department. Pratt was arrested by the police (though Kovač helped bail him out) and was put before the review board at the hospital for an explanation of his actions. Surprisingly, Pastor Watkins of First Mission Baptist and his congregation showed up on Pratt's behalf and explained the entire story of his contribution. The board subsequently dismissed Pratt from any suspension, allowing him to retain his medical license and job. Near the end of the season, Kovač asked Pratt to be best man at his wedding and Greg said yes.
