The players Deaths was spoiled before the games, it can happen in season 3

In season one, Sangwoo came back to the game when he was about to commit suicide. Then he killed himself in the finale. Sae-Byeok put a knife to his enemy's throat and his throat was cut. Ali betrayed his boss and died as a result of betrayal. Deok-su jumped off a bridge while running away from his enemies and died after falling off the bridge. In season 2, we don't know what many characters did before entering the games, but we saw 222 on birth control and 246 trying to save her daughter. Therefore, we can see that 222 died while giving birth. Since 246 is most likely not dead, she may leave the games and sacrifice herself for her daughter.
