Pala who was left behind due to the crowd that prevented him to get through was catching up with the train that Liu and the others were in using a rail cart. Using Golden Hair Pala after drinking his potion made him catch up to the train and jumped with a death-defying leap to board the train.

"Success... I barely made it" Pala muttered with an exhausted voice. He reached into the doorknob and tried to open the door, only to realized that the door was jammed by something on the inside, he bashed his shoulder towards the door several times to open it but it refused until his final attempt which opened the door before seeing a "Dead" Pululu on the floor with a black bruise on its head. 

"Hey, are you alright?" Pala asked before assisting the Pululu's aid but it didn't respond nor breathed which caused Pala to panic. Soon he heard a voice coming towards him so he hid in the bathroom all he could hear was a female voice screaming a murder as the other passengers came to the location along with the other Running Men. The Yellow Impala shivered in fear, biting his nails from the thought of him committing a murder, soon he heard a loud male voice, it was Detective Frick. he peeked from the door and watched as the Detective blamed the Running Men for his crime. With the Detective's badge showing his badge on his black Bowler Hat. Cuffing Liu with Popo, Lonky with Kuga, Miyo with Gai, and Yuu with... both of his hands.

"Wait this seems unfair for me" Yuu commented with his usual lazy gaze.

"You are all suspects and fugitives on this train!" Said the Detective "By 32 years in the field and 430 arrests have given me a keen instinct on the crime scene and that instinct are telling me that you are the suspects!"

"Shouldn't you be looking for clues first before instincts? Just saying" Said Yuu

"Shut it! You have the right to remain silent"

"We're all innocent!" Yelled Popo

"At least tell us why you think we're all guilty," Lonky asked

"Alright, if you find it a bit difficult to admit your crime then let me explain it step by step... You all are a group of professional hitmen and you planned this crime against this victim at least 6 months ago, and when you found the right opportunity to steal the victim's drinks, The monkey lured the victim into the free-planned position, blocking their entry and exit points so they couldn't leave... To cover this up as a simple train robbery, you even tried to steal his properties! But you can't fool me with that. You couldn't even prepare for the ticket check so you framed the victim for stealing your tickets. With the crowd accusing the victim of theft you planned to use your ultimate weapon, the tiger to end his life. Chasing them to the last train cart and executing a death strike. That is why you fools are the culprits!" Yelled Detective Frick, pointing his pipe towards them.

"The heck? You assumed we planned this crime for 6 months and we simply forgot about buying a ticket which was a normal routine for a train ride? And where was I in the flashback?" Yuu asked in confusion.

"Hehe, Funny you should say that because you were their lookout! but you fell asleep on the job where I slip right past you and solved the case!"

"Bruh..." Yuu muttered as the other Running Men complained. Soon Liu decided to solve the mystery on his own and saw Footprints on the spilled drinks leading to the bathroom.

"Look Footprints!" Liu yelled as they all looked over at the clue

"And see this injury on the Victim's head? Mr. Detective if Kuga was the one to attack then he would have done a lot more damage" Liu stated as the others nodded

"Don't try and talk your way out of this one, the evidence~" Frick was cut off by Liu.

"And judging by this dent on the door it seems like this was the reason for the Victim's death."

"Heh, so you are confessing that you used the door to kill the victim?"

"Bruh..." Yuu and Miyo muttered.

"After Killing the Victim, you probably fled out from the seen through this Laboratory!" Frick opened the bathroom door where Pala hid but was gone, only an opened window was left with black handprints on the ledge which Liu immediately suspected.

"I think you're right, looks like someone hid in here and escaped through the window"

"Yes, you guys left through the window, suspects always Lie but the evidence speaks the truth!" Frick stated.

"Bruh..." Said the Running Men in unison.

"Time for a field trip, follow me," Said the Detective before climbing out through the window and on top of the  Pala is seen from a distance. "Hey! Excuse me! It's dangerous out here Please go back inside!" Yelled Frick to reach Pala but he was too far away as the winds were blowing the sound of his voice backward. As the Train went train a tunnel, Pala entered the train through a ceiling vent. Soon Rick and the other Running Men tried their best to push forwards through the strong, harsh wind, although Kuga seemed fine since he was aerodynamic while Yuu hid behind Kuga so the wind wouldn't push him. Meanwhile, Pala was on the floor after falling from the ceiling vent. 

"How did it come to this... I just wanted to go on tour with my friends..." Pala muttered before Frick and the others fell on top of him, but the dark light due to the tunnel prevented them from Noticing Pala.

"Jeez... I got dust all over my face now" Liu muttered

"I feel fine..." Yuu responded with a light shrug.

"That's because you are covered in bandages," Said Gai before Lonky managed to grab a towel and gave the others a spare. After they wiped their dusty faces, they were shocked to see their face mark on the clean towel. Just as the train was about to exit the tunnel, Pala managed to escape leaving his face mark on a towel he used which was on the floor. 

"Huh? Whos this?" Liu muttered before picking Pala's towel off the ground.

"Anyways, you illegally slipped away from the crime scene through the roof then returned to the crime scene when you heard the screams as if it was your first time being there," Frick stated while Pala arrived back at the crime scene.

"Wait why am I back here?!" Pala muttered before accidentally stepping onto the red chalk that Frick dropped. In a panic state, Pala hid somewhere where no one can see him. The Running men arrived once more at the scene of the crime where Liu noticed the broken chalk where Pala stepped in before smirking.

"The mystery is almost solved" Liu muttered before picking up the chalk and drawing at the blank wall

"Three footprints so the suspect has three feet..." Liu muttered once more before drawing three feet on the wall. "Scratch marks on the bathroom window so the suspect has two antlers... The suspect escape through the window and entered through the Ventilation shaft like us and wiped the dust on his face with this" Liu showed them the towel that Pala used, intriguing them to learn more.

"So the suspect has three feet, two antlers and a face that looked like it had an allergy while wearing glasses... sounds like an alien" Yuu commented

"The suspect is here,  right now" Liu pointed at the red footprints from the chalk.

"These are new, suspects always return to the scene of the crime" Liu stated before they followed the Footprints.

"And our suspects are..." Tension was build as they gulped from the thought of finally seeing who the real suspect was which was on top of the vending machine but they were all in shock to see it was Pala, hiding on top of the vending machine.

"Pala?!" Said the Running Men.

"This deserves that fail trumpet sound..." Sad Yuu. Pala fell from the Vending Machin and hit the cold hard ground.

"I Just wanted to join you guys on this fun-looking trip...  didn't mean to kill anyone... That's all I wanted!" Said Pala with tears falling down his eyes. The detective smiled softly and helped him up...  before cuffing him of course.

"Hey detective, there is no way Pala could kill someone" Liu stated and the others agreed.

"Yeah, he's too pathetic to do that" Soon the victim's body arises from where it was with its eyes flushed in dark red as if something happened to him. The Running Man team was alerted as it walked towards Pala slowly from behind him.

"Pala look out!" Yelled Yuu before The victim Tackled Pala and bit him by the hand turning Pala into a flesh crazed Zombie.
