I really wanted Ali to make it because he was so sweet but before they found out about the marble challenge when he and Sang-Woo were like "We're going to work together and get through this" I turned to my partner and said they're all gonna end up playing against each other so one of them is going to die.
I was punching the air when I correctly guessed the identity of the Front Man!!
It was when the detective read in the file that his brother won in 2015, I theorised that maybe he ended up succeeding the previous Front Man for some reason.
I was expecting him to be younger though so it threw me that he was older. Looking back though the detective found a card in his room, so he must have been invited to be the Front Man? That would also explain someone else's theory that he squandered all his winnings if he was living in that tiny room and was offered some sort of second chance. But then I'm sure it's said that the Front Man has been doing it before? Idk
Annoyingly I then spoiled the twist ending for myself when I accidentally read something online about the old man! I felt so betrayed because he was so sweet
I do think it would have been more poetic and done Gi-Hun's kind side justice had he and Sae-Byeok got through to the final against each other and he fell on his sword to let her win. I hate that Sang-Woo redeemed himself at the last minute when he had been so selfish up to that point.
However all of it went on to prove that Gi-Hun won purely out of luck and also because others helped/saved him. He wasn't the main character because he was the main character, he was the main character because if you played it backwards to figure out why that person won you would find it was all down to chance and circumstance and not skill or strategy. I think him being kind to other players saved him without him realising.
