For Grimm fans, the wait was finally over as the show returned for its fourth season with episode “Thanks For The Memories.” The NBC supernatural drama aired Friday.

Nick Burkhardt (David Giuntoli) was a normal investigator in the homicide department of the Portland Police Department until he learned of his lineage. He was descended from a line of Grimms, who are able to see other worldly creatures called Wesen. 

With this gift and curse, Grimms are responsible for maintaining the balance between humanity and the Wesen mythological world. Over the past three seasons, fans see Nick and friends take on the journey of doing just that.

While “Grimm” featured creatures brought to life from many different pieces of work, many were inspired by the characters of “Grimm’s Fairy Tales.”

Avid watchers were left with the cliffhanger that ended season three, which was \ a wedding from Hell, for lack of a better term.

 Back at Nick’s apartment lied ex-federal agent by day and Wesen by night Weston Steward, decapitated in the front room.

Newly discovered Grimm Theresa Rubel (Jacqueline Toboni) was responsible for the beheading and, as expected, had some unanswered questions. 

While the authorities were skeptical of her calmness following the incident, Rubel was able to maintain her composure and story long enough to satisfy her self-defense claim. 

 No one knew how this worked in relation to proportional response, but hey, it’s best to not question it.

Nick and his girlfriend Juliette (Bitsie Tulloch) are forced to confront some serious relationship issues in this episode; the main problem stemming from the fact that Nick had an affair. In his defense, he had no idea he was even having it. 

Wesen creature Adalind, who appeared as Juliette, came to Nick. 

After their sexual encounter, Nick not only discovered the truth of his infidelity, but also realized that in sleeping with Adalind he lost his Grimm abilities.

As Nick carried on with his now ordinary police job, viewers are introduced to a criminal who attacked citizens and left them completely dumbfounded and seemingly memory-less, unable to identify their attacker. 

Most importantly are the circumstances currently surrounding Captain Sean Renard (Sasha Roiz). Not only is he the high-ranking officer that Nick and other detectives report to, but he is also half-Hexenbiest. 

That being said, he knows of the supernatural world and of Grimms. While his intentions toward Nick are questionable in the beginning, he became a form of protector to Burkhardt over time.

Throughout the hour-long season four premiere, Captain Renard laid in a hospital bed surrounded by medical professionals and hospital staff. After being shot by the now headless Weston Steward, his future is looking a bit grim. 

The show is a little farfetched, if that wasn’t made obvious. However, so are the Brothers Grimm’s folklore and dark fairytales that have become so world renowned and widely loved since the 19th century. 

The actors and the effects make for a pleasurable viewing experience, and the show is able to accomplish violent scenes without making gore scenes too stomach churning.

For a supernatural drama and occult detective fiction television show, “Grimm” is wonderful; just ask the 5.3 million viewers that tuned in for its airtime Friday. 

Watch the second episode of season four on NBC at 9 p.m. on Friday.
