A month later, Team Tangsooyook took on the 36th Floor test and Baam passed out again. As the team mused on his condition, Ha Jinsung appeared. Meanwhile, on the train, Rachel's group overcame a surprisingly difficult puzzle before defeating a guardian and unsealing Hoaqin's first part. As Jinsung inquired as to what happened to Baam, Hoaqin got acquainted with the people around him. Jinsung told Baam and his companions that they should not pursue the train and then escorted them away. On the train, Hoaqin and Rachel's group encountered Yeon Yihwa and Ja Wangnan and captured them after a minor altercation.
While Hoaqin and Rachel's group passed the train's 36th Floor stage test, Khun executed a plan that allowed Team Tangsooyook to escape from Jinsung and head for the 37th Floor station.
