Captain Kirk, Spock, and Scotty left the diner and spotted something that looked like a Broadway theater from New York City.
Curious to see as if it would fix any of their problems, Captain Kirk, Spock, and Scotty entered the theater for anything that could be some use to them.
They entered a stage area, and it was nothing but dark.
"Why is it so dark in here, Captain?" Scotty questioned.
"Obviously, Mr. Scott, there isn't a show being taken place, at the moment." Spock replied.
"No…but we certainly a part of a show, that's for sure." Captain Kirk spoke.
"I would certainly feel a whole lot better, had I knew what on haggis's moon is goin' on here." Scotty remarked, frustrated.
"Me too, Scotty," Captain Kirk answered.
As they were about to continue investigating, spotlights appeared out of no where and shined on the three Starfleet officers.
"What in tar nation is this," Scotty exclaimed.
Music began playing, and soon enough, a song known as "Summer Nights" from the musical, Grease, was playing and other people joined them in singing.
Captain Kirk sang Danny's part, and a Cruon girl sang Sandy's part. Scotty was a man in Danny's group that had a solo once and a while. Spock stood by the bleachers and watched his friends do another musical number. Soon after the song began, different colored lights turned on and changed from red, to orange, to green, to blue, to purple, to pink, and back again.
They sang their final chord and got into their finishing poses. After that, the other women and men left the area, leaving only Captain Kirk, Spock, and Scotty the ones remaining.
"This is ridiculous, Captain," Scotty cried.
"I agree, Scotty, this madness needs to stop." Captain Kirk answered.
"If only Mr. Spock could interpret those readings." Scotty exclaimed.
"On the contrary, Mr. Scott; I've been slowly fixing my tricorder's functions to measure the amount of brain activity and hormones being active before, during, and after these singing episodes you and the Captain continue to suffer from." Spock answered.
"What have you found out so far, Spock?" Captain Kirk questioned.
"It appears that both you and Mr. Scott have had an increase in endorphins, since arriving here on Cruon VI." Spock responded.
"What about you, Mr. Spock?" Scotty questioned.
"Considering I am still well under my trance, I do in fact have an increase of endorphins, but the process has stopped, since putting myself into the trance." Spock replied.
"So, when the trance wears off," Captain Kirk began.
"Then I shall resume the process of increasing the amount of endorphins in my brain." Spock answered.
"You can put yourself back into the trance, right?" Scotty questioned.
"Only if I do it at the correct moment in time, Mr. Scott." Spock answered.
Captain Kirk nodded.
"Alright, gentlemen; shall we continue investigating?" Captain Kirk questioned.
"Aye, sir," Scotty answered.
"Affirmative, Captain," Spock replied.
The three men continued walking around and examining and looking for anything beneficial to them that could possibly stop their urges to dance and sing, and possibly figure out what was causing this erratic behavior in the Cruons.
Hours later…
Captain Kirk, Spock, and Scotty headed back to their hotel and sat in the lounge. Captain Kirk was drinking a glass of some sort of drink, and Scotty wa drinking a big glass of Scotch, while Spock had a glass of water.
"How are we gonna figure out what's causing all this musical chaos to take place, Captain, if we don't even have the smallest lead?" Scotty questioned.
"Good question, Scotty; Mr. Spock, do you have any ideas?" Captain Kirk questioned.
"None, Captain," Spock answered.
As they were about to say something else, music began playing softly in the background then growing louder. It was the song "One" from the musical, A Chorus Line. Captain Kirk began to smile a little, then frowned.
"What, Captain," Scotty questioned.
"Oh, this was just Bones's favorite song from his favorite musical." Captain Kirk answered, sadly.
Scotty smiled, thinking of Dr. McCoy, then gave a sour frown, and managed to fight off his heartache, so he wouldn't start balling. Spock sighed, not helping but not finding Dr. McCoy not there with them logical.
"Captain," Scotty began.
Captain Kirk looked at Scotty.
"Do yah think Dr. McCoy's in heaven?" Scotty questioned.
Captain Kirk smiled.
"If he's not in heaven, then the three of us are in some huge trouble." Captain Kirk chuckled.
Scotty sighed, then drank more of his Scotch.
Spock felt the sudden urge to dance, but closed his eyes and began to put himself in his trance, since it had worn off. Captain Kirk and Scotty began swaying back and forth then got up and began singing and dancing to the melody and rhythm. Spock came out of his mind meld, and was again in his trance, as he looked over and watched Captain Kirk and Scotty dance and sing a long to the music and lyrics. He turned on his tricorder and began taking more readings on the insane increase of the amount of endorphins in Captain Kirk and Scotty's brains.
Captain Kirk and Scotty finished their number then quickly sat back down.
"I think we've gone mad, Captain." Scotty wailed.
"And, I am correct of the endorphin levels; whenever you and the Cruons begin to sing and dance, your endorphin levels go up beyond normal circumstances which create to put you in a type of euphoria until the song has resolved itself." Spock stated.
"So, what does that mean, Spock?" Captain Kirk questioned.
"Right now, your endorphin levels have lowered down due to stress and worry. When you two begin to sing, those endorphin levels increase dramatically sending you into what is a slang term known as 'slap happy'." Spock replied.
"So…you mean to tell us, if we can manage to keep our endorphin levels down enough, we won't sing or dance." Captain Kirk replied.
"Correct, Captain," Spock answered.
"So, how do we manage to do that," Captain Kirk questioned.
"…I don't know, Captain," Spock answered, modest.
