Episode 6 squid games - room 33

During the game on episode six 6️⃣ on the new season of Squid Games, groups of 4 people are supposed to go into each room before the door locks. One group went in with only 3 people, which happened to be room 33, and is the only room in the round to be eliminated.

The shooter happens to have the triangle pattern on face, and last scene closes out with their face centered in the peep hole (all seeing eye, black&white duality)
