Lewis goes off, wondering who is going to be next. Det. Falsone comes to the squad with news about why he thinks Beau Felton killed himself. Lewis and Stivers discuss the Mahoney shooting. Cox finds something interesting about the Felton case; she digs in deeper and the results change the case to a murder. Bayliss turns up the next day and disappears again to his Uncle George's place.
