As finalists, Gi-hun, Sang-woo, and Sae-byeok are given a change of formal clothes. Sae-byeok hides a severe stab wound she received from the glass bridge explosion. After eating dinner, each player is left with a steak knife. Gi-hun suggests to Sae-byeok that they should ally against Sang-woo, realizing he will go to any length to win. Sae-byeok instead begs Gi-hun to promise that whoever wins the game will look after the other's loved ones. Gi-hun goes to kill Sang-woo when he falls asleep, but Sae-byeok stops him, telling him he is not a murderer. Sae-byeok's injury worsens, prompting Gi-hun to call for help. When Gi-hun is away, Sang-woo kills Sae-byeok and the staff arrive only to collect her corpse. Furious and heartbroken, Gi-hun tries to attack Sang-woo but is prevented by the staff. Meanwhile, Jun-ho makes it to another island but is quickly tracked down by the Front Man and the staff. To Jun-ho's shock, the Front Man reveals himself to be his brother, In-ho, who tries to recruit him. When he refuses, In-ho shoots Jun-ho in the shoulder, causing him to fall back over a cliff edge into the sea.
