Reacher season 3 will see Jack Reacher partner up with Sarah Duffy, following the same pattern as with season 2’s Dixon and season 1’s Roscoe. Widely considered one of the best Jack Reacher books, Reacher season 3 is adapting Lee Child’s Persuader and will see the titular hero go undercover within another criminal enterprise. In the process, Reacher season 3 will see Reacher (Alan Ritchson) cross paths with Sarah Duffy (Sonya Cassiday), who oversees the operation. As confirmed by the trailer, their dynamic won’t remain platonic.
