Many were concerned about how 9-1-1: Lone Star would handle Sierra McClain’s exit in season 5, and, unfortunately, her character’s absence has led to some problems that could make Grace the villain. The Fox procedural drama TV show created by Ryan Murphy, Brad Falchuk, and Tim Minear is a spinoff of 9-1-1. It premiered in January 2020 and follows a group of first responders living in Austin, Texas, including McClain’s Grace, who has been around since season 1.
