On Friday, "Grimm" will be entering its sixth and final season, and the fantasy series will finally be looking to provide viewers with answers to some really big questions. The final season of the show is scheduled to have 13 episodes and will be getting down to the truth surrounding the keys, the magic healing stick, the changes that have been taking place in some of the characters including Eve and Diana, and the introduction of a new and very sinister force.

In an interview with Access Hollywood, David Guintoli, the actor who plays Nick Burkhardt, says "you couldn't fit a frame of film between the end of last season and the beginning of this one." This means the season premiere will begin where last season's finale left off with the gang still underground and still unaware about the fate of their friend Nick.

"You're going to get a lot of answers", says Reggie Lee, the star who plays Sergeant Wu, in an interview with IGN. He also adds that the final season's story will tie everything up and provide fans with the answers that they have long been looking for. But at the same time, he also says that viewers should feel nervous because a lot will be happening in season 6.

One of the best things that the show has going for it is that everyone involved in it knew that this season going to be the end. Many of the cast members spoke in length about how grateful they were to have a chance to end "Grimm" with a final season, and called the ending of the show a "bittersweet" moment for them.

Bitsie Tulloch's character "Eve" will also be facing some struggles throughout the final season. In the finale of season 5, Nick and Eve both had a moment before they headed towards the tunnels with the rest of the group. It was during this moment that he thought he saw Juliette coming through. This could prove to be one of Eve's major struggles in season 6.
