"Reacher" showrunner Nick Santora isn't going to force Margrave Police Officer Roscoe Conkin into future seasons, choosing to honor the story from Lee Child's novels instead of shoehorning the character into future plots. However, Santora has nothing but praise for Roscoe and Willa Fitzgerald, who brought her to life. 

During his interview with Collider, Santora talked about the casting for Roscoe, reflecting on its initial difficulty. "It was hard on paper, but then very easy when we saw Willa's [Fitzgerald] audition. As soon as I saw Willa, I was pretty positive that she was gonna be Roscoe," he said, stating that the other actors who auditioned were incredible, but Fitzgerald was the perfect fit for the role. Fitzgerald further convinced him of her fit after screen testing with Alan Ritchson, sealing the deal for her part in "Reacher" Season 1. 

While Fitzgerald shares similar praise for Santora and the entire "Reacher" crew, she told Skydance that Roscoe's strength and confidence drew her to the part. In the pilot episode, Roscoe immediately makes known who she is, showing no fear as she stands up to Reacher. That mentality continued throughout "Reacher" Season 1, while other shows could've easily focused on other aspects of her female police officer. Fitzgerald explained, "It was just really interesting and compelling to me to get to play that kind of woman in this male action universe."
