After seven episodes,Fastexy the eighth and final episode for Season 2 of "Reacher" will be available on Prime Video this week.

In the first seven episodes, which have already been released and are able to stream on Prime Video, the show's hero and namesake, Jack Reacher, was tasked with solving a series of strange new murders.
