The frightened De Lan than confessed that he didn't mean to rape Quan Na and that it was all Zhu Cai'er and Fu Ming Ti's fault. After hearing that, they got a phone call from the hospital that said that Duan Ze was somehow suffocated to death while saying sorry to Quan Na and begging for his life from Ren Yu. Then, the janitor came and told them that Zhu Cai'er is found dead in the girl's bathroom and indeed, more blood dots were missing from around the painting.
When they went to the scene, the bathroom was flooding with red water and the blood came from the dead Zhu Cai'er, who was nude. Having figured out who the six people are, they decided to gather everyone in a group and protect them for the night while trying to find a way to appease Quan Na.
