"We're back!" Heechul and Han Geng came back to the Idol Mansion after spending the night at Heechul's home.

"Welcome back." Jungsoo was first to greet them. "So... How did it go?"

"Better than we expected. And they seem to be okay with our regular zombie selves." (Han Geng)

"That's..." Jungsoo sees Heechul staring at the window. "Is he okay?"

"I don't know." Han Geng answers in a worried voice. "He's been acting like that since last night."

"Maybe something got onto his mind?" (Jungsoo)

"If so, I would've noticed." (Han Geng)

Days passed in a flash. Everyone was getting ready for their Halloween event. Everyone expect Heechul...

"Is Heechul oppa okay?" (Yuri)

"Yeah, he's been stuck in his room for a while now." (Taemin)

"We wanna know too." (Youngwoon)

"Even Hankyung hyung can't get through to him." (Kyuhyun)

"Maybe something happened back home?" (Kibum)

"Again, if it did, I would've noticed." Han Geng reminds them.

"But we never seen him... sulking." (Key)

And he was sulking. Just sitting on his bed while petting Heebum. The feline doesn't really mind since he doesn't have to feel anything.

"What now..."

[Meow?]

"Scared..."

What is he scared about? He's been acting like since he visited his family. Maybe a bad memory popped up in his head?

"Son..."

[Meow?]

"Heebum... What... do I... do now?"

Heebum doesn't answer. Of course, because he's a cat...

"Nothing's in the vents." (Mr. Kim)

"Nothing's in the pipes either." (Yoowan)

Han Geng told Heechul's family that he kept sensing something in the laundry room. So they checked all the vents and pipes but found nothing.

"Maybe it's the furnace?" (Heejin)

"At this time? It's still only October." (Mrs. Kim)

And she's right. Even though the weather has become colder, it's still not cold enough for the furnace to run.

Then Yoowan finds something behind the dryer. "Funny. Why is one of Seonju's shoes here?"

"Maybe he wanted to wash them?" (Heejin)

"Um..." Yoowan shows them. "They're leather..."

"Leather shoes behind the dryer? Wait..." Mrs. Kim remembers a clear detail. "Seonju wore those when he left!"

"And he doesn't have another pair in the same style..." (Mr. Kim)

"You don't think..." (Heejin)

"I do think. This is really bad." (Yoowan)

"What now?" (Mrs. Kim)

"I think it's time." (Mr. Kim)

Meanwhile, with Finale...

"Another job well done!" (Rico)

"You said it, bro. And I can't believe it's Halloween already." (Ando)

"Halloween event, here we come!" (Lueun)

"Has anyone seen Seonju hyung and Woorin hyung?" (Ireun)

"I think I know..." (Xin Jing)

Seonju's been sulking on the balcony, thinking about something.

"Why..." (Seonju)

"Why what?"

"Huh? Oh... hey, Woorin." (Seonju)

"Is something going on?" Seonju tries to brush it off but... "I know that face. Come on, just tell me."

"Okay. I kinda... lied to my family?" (Seonju)

"You did WHAT?!" (Woorin)

"I didn't do anything illegal. I just lied to them that I had to go out of town for work." (Seonju)

"But... Why did you do that?" (Woorin)

"I needed answers." Seonju starts shivering. "About my father."

"So..." (Woorin)

"So, when I overheard something about Heechul hyung and Hankyung hyung coming over, I had to find out what's really going on." (Seonju)

"You and Heechul hyung are relatives. You know that." (Woorin)

"Yeah, but my grandparents and aunt mention him and Hankyung hyung a lot. People don't really talk about their distant relatives so frequently." (Seonju)

"You're right. That does sound weird." (Woorin)

"And..." (Seonju)

"And what?"

But as soon as Woorin asked that, Seonju started crying.

"I... My father..."

"Your father? But he died years ago." (Woorin)

"No! Well, kind of? Yes, he did die... 18 years ago..." (Seonju)

"So why are you mentioning him now?" (Woorin)

"Super Junior..." (Seonju)

"Super Junior? What do they got to do with any of this?" (Woorin)

"EVERYTHING!" (Seonju)

"Huh?" (Woorin)

"My father was assaulted by my "mother" during university. He was an aspiring author. He was killed by that woman and her husband. Heechul hyung knew everything about this." Seonju listed what he could remember in his head.

"Maybe it's because your family told him?" (Woorin)

"Or maybe..." (Seonju)

"Maybe what?"

"Woorin, haven't you realized the similarities between Siwon and your favorite actor?" (Seonju)

"Well... A little bit." (Woorin)

"NOT A LITTLE BIT!" Seonju shows him pictures he got off the internet. "This picture of this actor from 2002. Siwon in 2023."

Now Woorin realizes, "The same face..."

"And I don't think it's just a conicidence." (Seonju)

"Wh-what are you saying?" Woorin asked in a shaky voice.

"They're not alive..." (Seonju)

"Not..." (Woorin)

"And so are the rest of Super Junior..." (Seonju)

"Are you-" (Woorin)

"I'M SURE OF IT! And I saw them too..." (Seonju)

"You mean?" (Woorin)

"Without their makeup... And I saw their scars..." (Seonju)

"Seonju..." (Woorin)

"Heechul hyung... He's my father!" (Seonju)

He finally said it. And Woorin still can't believe it.

"We've been seeing walking corpses this whole time..." (Woorin)

"No, not corpses..." (Seonju)

"Huh? What do you mean?" (Woorin)

"They don't bite, they don't walk like the zombies in those movies..." Seonju lists everything he can from his mind. "And the incident at the Busan Art Gallery..."

"He lost his memories..." (Woorin)

"Not just that... He lost his human consciousness..." (Seonju)

"Than doesn't that mean he's-"

"He's not!" Seonju cuts Woorin off again. "He's gotten most of it back. He recognizes my grandparents, aunt and uncle. And even the kids..."

Woorin still couldn't piece everything together. But the things he didn piece together, that's when he realized...

"I've been working with my idol this whole time... And that phrase!"

"Vigilance makes a professional."

"Siwon... I mean, Siwon hyung? How does this work?!" (Woorin)

"I think we should stay silent about this." (Seonju)

"But-" (Woorin)

"Just until the time is right. We can't just bombard them with sudden questions." (Seonju)

"Seonju..." Woorin can see both what Seonju has endured and his determination to keep Super Junior's secret.

"Woorin, let's not tell them too. You know how they'll react when if we tell them."

"You're right. For them." (Woorin)

"For them." (Seonju)

Now 2 of the Finale members know Super Junior's biggest secret! How will things so from here?
