The biggest twist in Squid Game season 2 saw Lee Byung-hun's Front Man join the game in disguise as a player, borrowing a trick from the former Host, Oh Il-nam, and going undercover as Player 001.
While the audience knew Oh Young-il was really Front Man (real name In-ho) himself, Gi-hun remained completely unaware – even during the dramatic Squid Game season 2 ending, which saw a newly re-masked Front Man shoot Gi-hun's best friend Jung-bae dead, right in front of him.
