On the March 6 airing, Nana was driven to tears after receiving a good talking-to from the drill sergeant for the way she talks. The sergeant had asked her, "Why do you think you were called out?" and Nana answered, "My head remembers but my body doesn't follow."
The sergeant was unsatisfied with her response and scolded her, "The way you talk doesn't reflect instructor-like behavior." Nana replied, "I don't think I'm used to it yet," to which the sergeant sharply remarked, "If you are committed to the training, then you should change your attitude first. If you act up again then you will be reprimanded."
At the sergeant's unrelenting rebuke, Nana couldn't help the tears that welled in her eyes. The idol poured out her frustrated heart during the interview with the production crew, saying, "I've been trying to fix the way I talk. I heard that I 'fool around' a lot. It can't be helped but it was really hard [for me]."
