For this episode, contestants from Produce 101 Season 1 Kim Sohye, Choi Yoojung and Kim Sohee appeared as special panelists. The episode opened with the remaining 98 contestants from each company entering the main studio by company. In between announcements of each trainee's ranking, events leading up to the elimination were shown, such as their dorm life, exercise, and a hidden camera prank. I.O.I's Kim Doyeon and Choi Yoojung met with the trainees and hosted a dance battle among the trainees, in which Hong Eunki was crowned "Dancing King". A poll for 'Top Visual' was also conducted, in which Park Jihoon was ranked 1st. Lee Daehwi was ranked 7th in the ranking announcement, the shocking fall in his rank surprised everyone. After announcing the top 59 trainees, BoA announced that the last trainee to be saved from elimination was Kim Sangbin, ranking 60th. At the end of the episode, BoA announced that the team formation for the 3rd mission, which was the concept evaluation, would be decided by online voting. This was a major difference to that of Produce 101 Season 1, where trainees got to choose the song they wanted.

Explain Yourself
The trainees were allowed to do a segment where they asked the other trainees to "explain themselves" about certain topics, for humorous fun.
- Kang Dongho was confronted about his stubble and "manly" face on camera when he chose not to wear makeup.

- The MMO trainees were confronted for talking so much on camera. The fans made a joke that MMO stood for "말많오" [Mal Man Oh], which means to talk a lot. The trainees blamed Yoo Jisung, who's nickname is "Auntie" because he talks so much.
- Noh Taehyun was confronted for crying on camera so much. Fans started calling him a "fruit", not because he is refreshing, but because tears ["juice"] is constantly coming out of his eyes.
