The CW TV series "Supernatural" reached another milestone with their 200th episode. The entire production team of the show decided to thank the fans through the fifth episode of "Supernatural" Season 10 titled "Fan Fiction."

Spoiler Alert: This feature contains major spoilers on "Supernatural" Season 10, episode 5 titled "Fan Fiction."

The students are rehearsing for their "Supernatural" musical production but a conflict between the director and a cast member made their teacher walk out on them because there is too much drama in the drama department. However, the teacher disappeared when something grabbed her from the bushes and left behind a purple flower.

Dean Winchester (Jensen Ackles) comes across the missing teacher case then convinces his brother, Sam (Jared Padalecki), to work on it because going out on a hunt makes him feel normal. The Winchester brothers head to the all-girls St. Alphonso Academy to conduct their investigation.

Sam and Dean were stunned to see that the school is working on a musical play about them. The Winchester brothers talk to Marie, the student director, and May, the stage manager, regarding their missing teacher.

After several protests from Dean over the "Supernatural" musical, the brothers decide to split up to further investigate on the case. There is not enough evidence to prove that they are dealing with a monster so Sam and Dean concluded that there is not a case here.

However, Marie was forced to call the "FBI Agents" back because another cast member from the "Supernatural" musical play was grabbed by their prop scarecrow. Marie recounted that she and the second victim, a student named Maggie who portrays Sam Winchester, had an argument that led to Maggie's decision of quitting the production.

Marie is now convinced that monsters and ghosts are real because she witnessed the scarecrow grab Maggie with another purple flower left at the scene. Sam, Dean, Marie and May dig into the mysterious case of the scarecrow.

Sam's research revealed that they are dealing with a goddess called Calliope, who protects the musical play's author and director until her vision is realized. When that happens, the goddess muse of epic poetry will eat the author.

Sam and Dean tell Marie that the "Supernatural" musical play must go on in order for the Calliope to appear and they will be around to stop her. Marie starts to panic but Dean was able to calm her down and convince her to believe in their musical play.

Marie, who now takes on the role of Sam Winchester, introduces the musical play with the Winchester brothers standing by backstage. The scarecrow shows up just a couple of minutes after the production started, grabs the real Sam Winchester and disappears before Dean could stop the scarecrow.

Sam regains consciousness at the school basement where the teacher and Maggie are locked up. The Calliope finally reveals herself and explains that something about the "Supernatural" musical play attracted her attention.

While the goddess was busy explaining herself to Sam, Maggie grabs a book and hits the Calliope on the head. Sam saw the opportunity to take down the Calliope while Dean was busy fighting off the scarecrow onstage when the supernatural creature showed up again to grab Marie.

Marie grabs a stake and stabs the scarecrow at the same time that Sam stabbed the Calliope down at the school basement. The Calliope and the scarecrow also explode at the same time where the audience watching the musical play got covered in the monster's purple goo.

Sam and Dean stay behind to watch the students sing their emotional version of "Carry On Wayward Son" in their "Supernatural" musical play. Then, the Winchester brothers drove off after saying goodbye to Marie and May. Dean places the prop Samulet that Marie gave him on the rear view mirror of his "Baby Impala."

Back at the auditorium, May tells Marie that the ticket she left for the publisher of the "Supernatural" books got claimed. Marie excitedly talked to the publisher and even asked him what he thinks of the musical play. "Not bad," Chuck Shurley (Rob Benedict) responds.

"Supernatural" Season 10 will return with episode 6 titled "Ask Jeeves" which will air on Tuesday night, Nov. 18, at 9 p.m. ET on the CW Network.
