He wasn’t really scanned by the giant doll
People were too shocked by the game’s rules to notice this subtle distinction in Red Light, Green Light, but when the enormous doll turns its head around to survey the players for any signs of movement, she doesn’t appear to scan Il-nam thoroughly.
The doll’s eyes can be seen through the player’s, with a distinct green border and a green fog that turns crimson when motion is detected, although Player 001’s green foyer is not as intense as the others, suggesting that the doll was programmed to avoid him.
