Joint Fringe showrunner Jeff Pinkner won’t be seeing the show through its final 13 episodes, it was announced on June 19th.

According to a statement from co-creator J.J. Abrams, “We’re so excited to begin work on a fifth season of Fringe and to be able to deliver the 13 final episodes to our passionate and devoted fans. For four years, J.H. Wyman and Jeff Pinkner have worked tirelessly as a team to keep all the worlds in order on Fringe. We’re thankful for the invaluable contributions Jeff has made to the show and of course wish him well and look forward to working together in the future. J.H. Wyman’s importance to Fringe cannot be overstated, however, and I’m thrilled that he will continue as showrunner for the concluding chapters of our story. We can’t wait for our fans to see what we have in store for them in the wild conclusion of Fringe.”

TV Guide, who broke the story, added that Pinkner will not receive an executive producer credit on the final year and that it was an amicable split, caused by Pinkner’s desire to pursue other projects.

Pinkner posted on Twitter to say: ” Hey all! Me here, wanting to say once more: you are the single best, most devoted, most supportive, and, well… fanatical fans in the (red) universe! As you know, there would be no season 5 (or 4… Or 3, etc) without you!  I love you all (yes even YOU — you know who you are…) You are in good hands from here.  But don’t think you’re getting rid of me that easily. Again, much love!!! Jeff.”
