The Front Man discreetly took orders from Il-nam
Throughout the series, we saw how the staff couldn’t care less about what happened to the players outside of the six official games, so this scene from episode 4 does stick out.
It appeared like the Front Man was showing mercy on an old, frightened man during the first dorm room scuffle, but after we learned that Il-nam was, in fact, the game’s mastermind, it’s evident that the Front Man wasn’t taking pity – he was obeying orders.
