CBS Person Of Interest was given a reduced, 13-episode order for Season 5, it was left on the bench for fall and as of today, still has not been scheduled, signaling a likely post-upfronts summer return. If all that wasn’t subtle enough, executive producer J.J. Abrams today articulated fans’ worst fear — that the upcoming fifth season of POI will likely be its last.

“My guess is it is the final season,” Abrams said during a panel for his Hulu series 11.22.63. “The only heartbreak there is how much good story there was to come if it were to have continued.”

He confirmed that creator/executive producer Jonah Nolan and executive producer Greg Plageman are treating the upcoming episodes as POI‘s last.

“Jonah Nolan and Greg Plageman have done such an amazing job on the show. We don’t yet have a schedule, but I know these episodes will see the light of day. People will get to see these episodes.”

There are no current efforts to shop POI elsewhere, Abrams said.
