After renewing its popular supernatural police procedural drama earlier this month, NBC has now cut the "Grimm" season 6 order to just 13 episodes.

While a shortened season is still better than an outright cancellation, fans of the show are now worried that the downsized season may be an indication that the occult detective fiction could be on its way out. An episode order of 13 episodes is nearly half the length of a regular full order for a network television show, which typically consists of at least 22 episodes.

Deadline reports that with so many other drama series on its plate, NBC may have halved its "Grimm" episode order to give NBC executives some scheduling flexibility. The outlet also noted that there may, in fact, be more than 13 episodes in the next season, depending on how the network's schedule is organized.

As Deadline noted, 13 is not a fixed number. Though the season 6 order is said to be for a minimum of 13 episodes, there is a possibility that the pickup could be for more.

Meanwhile, "Grimm" actor Reggie Lee recently spoke about the surprising transformation his character, Sergeant Drew Wu, underwent in the previous episode, titled "Good to the Bone."

"It's interesting, because I didn't think I would ever be here," Lee told IGN. "I always thought I was like the human that was safe - safe being a relative term in 'Grimm.'"

According to Lee, he didn't know when he was shooting "Good to the Bone" that Sergeant Wu's transformation would be permanent. He also admitted that he read up on Neanderthals and werewolves in preparation for the episode.

"This episode and the next episode are really pivotal, and that's why I asked for a lot of [prep time]," he said. "I'm crazy about my prep time, but when there's an emotional change and a physical change, I think it's integral that I get it as accurate as possible for myself emotionally."

"Grimm" airs Fridays at 9 p.m. ET on NBC.
