Reacher season 3 expands the character of Jack Reacher and dives more into the life of Frances Neagley, franchise stars Alan Ritchson and Maria Sten reveal in a new ScreenRant interview. Jack Reacher is known to be a character who does things his own way, and the latest season of the Prime Video show leans into that. This season, Ritchson’s Reacher is set to do more on his own, stepping away from the season 2 storyline that saw him working with the 110th Special Investigations Unit.
