The TV show is actually based on the book series called “The Walt Longmire Mysteries” where Walt and Vic shared a romantic moment. Most fans of the TV series are quite against the idea of the two being a couple.
They believe that because of the glaring age difference, Vic is too immature for Walt and that the Sheriff only sees her as more of a daughter than a love interest.
But some fans of the show also liked the idea that the TV show follows what is written in the books for a change. If that is the case, at least, they would know that the TV series is following the book and its excellent storyline.
Before moving to Wyoming, Vic Moretti is a former homicide detective from Philadelphia. She is married to Sean Keegan and their relationship had its share of ups and downs to the point where Sean even suspected that his wife was having an affair with her boss, Walt Longmire.
Prior to getting married to Sean, Vic also had an affair with her married superior officer Ed Gorski while in Philadelphia. Vic was eventually forced to leave town after she turned in Gorski’s partner, Bobby Donolato, which led him to commit suicide and Gorski swearing revenge on her.
