The first three trainees to take viewers behind the scenes were Jung Dong Soo, Choi Seung Hyuk, and Yoo Ho Yeon. Jung Dong Soo took viewers through while his "Shock" team went up to line up for their meal, chatting with the camera about having to eat broccoli because of his diet, and more. 

Choi Seung Hyuk sat around with his fellow trainees, playing with the camera's zoom, while Yoo Ho Yeon attempted to interview his and his opposing "Replay" team members! During Choi Seung Hyuk's cam, teammate Lee Joon Woo came over, claiming to have something to show and tell. 

It was none other than a fancy toothbrush and case belonging to Choi Min Ki, or NU'EST's Ren! Lee Joon Woo claimed that because Choi Min Ki's toothbrush case was so fancy with a built-in light (for who knows what), he must be rich.
