Theory: Player 246 is ALIVE
Ok… So you know that player 246 is the father of the daughter (Girl with strawberry hat). And we know that triangle 011 (girl pink soldier) knows that he is her father. MY THEORY is that she was the one who shot player 246 when they surrendered near the end of episode 7. I believe that she saw and recognized him, and instead of fatally shooting him, she shot him in his shoulder: This would also put him in a coffin that would take him to the surgery room, which would 1) keep him alive so they could both make an escape, and 2) put her back on the black square boss’s good side, as he is mad at her at the moment. I think this could be a side story that could also allow the two to escape and give either the police or another group of people information on the whereabouts of the island.
