All good things must come to an end, so NBC has decided that its drama TV series “Grimm” has to bid the small screen goodbye for good after its sixth season.

The “final season” will begin on Jan. 6, 2017 and will consist of only 13 episodes as opposed to the 22 the show has been airing for each of the five previous seasons, according to Variety.

The news has saddened a lot of fans, who wasted no time in expressing their displeasure on social media with the hashtag “A Grimm Farewell.”

A fan named Jennifer Norris tweeted that she’s not ready to let the series go just yet, but she hopes its two stars will find a happy ending.

As for Twitter user Elodie, she has been anticipating the cancellation of “Grimm,” but that didn’t make the news any easier to handle.

On the other hand, the cast tried to maintain an optimistic stance regarding the cancellation. Lead star David Guintoli, who plays Nick Burkhardt in the series, said the whole cast and crew will probably get emotional filming the final season.

On his Instagram account (@mrgiuntoli), he posted the cast’s group photo and wrote, “Season 6 premieres Jan 6th. Grimm's Final Season. Will we go out with a group sob?? Probs. You have been the most splendid fans. See you in January. Love you all!”

Reggie Lee, who plays Sergeant Wu, also shared the same photo as he wrote, “Will truly miss this #wutastic family that causes one to make up words like #wutastic.”

As for Bitsie Tulloch, who plays Juliette Silverton, she guaranteed that fans won’t be disappointed with what they’re going to do for the final season. “While we're sad to announce the 6th season will be our last, we're thrilled to be going out with a bang,” she said.
