The True Killer's Evidence

Even Suk Min Joon confessed freely being the man behind the murder case 12 years ago. He asked, "Have you discovered the bodies I killed?" he exclaimed that he would not admit the crimes if they could not find the victims' bodies. Seo Do Won and Han Seo Kyung of "B" struggled to find the evidence they needed, but with no luck.

Suk Min Joon said that there was still one victim left and that he intended to commit more crimes as he left the investigation room. Seo Do Won thought that the bodies were still in the universe "B," and headed to the 8210 train to find them.

The Last Target

As the "Train" is hurtling towards its finale, viewers ask, "Who is Suk Min Joon's final intended victim?" Before Suk Min Joon left, he showed Seo Do Won the ring that belonged to Han Seo Kyung's mother and said that he would show Seo Do Won the ring on the hand of someone closest to him again.

Seo Do Won thought that Suk Min Joon's final target is Han Seo Kyung. Meanwhile, digging into Suk Min Joon's past, Han Seo Kyung discovered that his rare disease is passed down through maternal genes and that he seemed to change his last name. Han Seo Kyung then ran towards the Mu Kyeong police station, knowing the next target of Suk Min Joon.
