While "Person of Interest" season 5 release date has not been confirmed yet, fans are already up the wall.  

With no updates at all as to when the next season is coming, many wonder if the sci-fi drama is still going to air, if the next season is already going to be the end of the series, or if another network is going to get hold of the series after CBS.

In a previous interview, CBS president Glenn Geller said that the season 5 will premiere this spring. However, it is only a couple of weeks before spring but CBS still remains reticent about the much-anticipated premiere.

Writers of the show also recently posted a rather enigmatic message on Twitter, saying that the upcoming season may already serve as the finale of the series. The post was accompanied by a group photo of the cast and crew of the show, captioned #theend.

The cryptic post troubled fans, who immediately thought that their efforts to stave off the cancellation of season 5 had already come to naught.

Aside from the much talked-about premiere of the upcoming season, another controversy surrounding "Person of Interest" season 5 is the online leakage of its episode titles.

The leaked titles that surfaced online revealed that the upcoming season will have 13 episodes in total, with episode 13 entitled "Return 0." This has fueled speculations that the title of the final episode may be a sign that there is no coming back for another season.

With the leakage of the season 5 episode titles, there is a huge possibility that fans will still get to see the next season, albeit not sure if it is going to be this spring.
