Warning! This article contains spoilers for Reacher season 3’s finale.Neagley steals one of Jack Reacher’s best lines from the original Lee Child books in Reacher season 3 and, surprisingly, makes it sound even better. Since Reacher season 3 adapts Lee Child’s Persuader, it was initially not expected to feature Neagley as one of its characters. In the original book, Neagley does not help Reacher with his overarching undercover operation at all. However, given how Neagley showed up even in Reacher season 1’s ending moments despite not being a part of Lee Child’s Killing Floor, her appearance in season 3 was not surprising.
