Tracy Spiridakos' character Hailey Upton is a crossover from the NBC series Chicago PD.
Monica Raymund directed this episode. She was in Chicago Fire as Gabriella Dawson, another Dick Wolf-produced series.
This serves as the season finale with a shorter season due to the COVID-19 pandemic.
Allegedly Hailey Upton's (Tracy Spiridakos) crossover from Chicago PD was meant to last more than one episode, but Covid cut the planned story arc short.
