The girls prepare for the final showcase, where the Major and Minor teams will perform "Do It Again" back to back. The teams spend one last night together reminiscing on their journey throughout the show, laughing at each other's silly moments, and sharing their heartaches and hopes. The finalists are gathered on stage where the Major team turns in their necklaces. JYP then throws in a twist, announcing that Twice will be a nine-member group. Along with the current Major line up, he chooses one contestant from audience's opinion through online voting and one from the A&R Team and the Trainers' decision.
