After the cypher mission which ultimately resulted in the elimination of a couple contestants, the remaining rappers got to take a breather as they sat back and judged the producers' performances!�

This time around, the contestants were the ones reviewing the judging panel on their rapping in order to decide which producer team they want to join. The producers all put on the best stage they could by showing off their swagger and pouring forth their energy. Tablo and Jinusean, who were third to perform, brought on fellow YG mates Bobby and B.I. for added force.

Producers LOCO and Zico noted the special appearances of the iKON members. LOCO jokingly said, "I think Bobby and B.I came out too fast. It was enough seeing them in their previous performances [in the third season]." Zico shared similar playful sentiments, as he told the production crew, "In my opinion Bobby was cooler when he didn't come out."�
