So, here’s what happens [I actually didn’t understand till now and thought they were reacting to camera guy “eavesdropping” on them]

Kim Soo Ro wisely hid the flag with Jong Hyun who then terrified hides between the lockers.

This is apparently such a good hiding place that no one, not even his team mates know where he is. 

Good for the flag’s safety, bad for overall mission.

Eventually Jae Suk locates him.

Jae Suk then reports of Jong Hyun’s location, telling everyone to remain calm so that other team wouldn’t figure it out.

These are their “remaining calm” reactions.
