Squid Game fans spot tiny detail that may reveal identity of Front Man.

'This SHOOK me'

Season two of the hit Netflix series was released on Boxing Day, meaning many have already finished watching the second instalment of the dystopian South Korean show.

Set three years after the original events, the story follows Seong Gi-hun (Lee Jung-jae) as he re-enters the deadly competition with a new mission.

Minor Squid Game spoilers ahead.

Obviously, considering how the first season went, there weren't many characters who could return for the second series. However, one person who has returned alongside Seong is the mysterious Front Man.

The Front Man is a key figure who oversees the deadly games. In the first season, it is revealed that his identity is Hwang In-ho, the brother of police officer Hwang Jun-ho.

Hwang In-ho was a former winner of the Squid Game and later assumed the role of Front Man, orchestrating the games under the direction of the mysterious organisation.

Now, some viewers reckon they worked out a key part of the character's past thanks to one innocuous line from the series.

In a post on X, one fan recalled how Player 001, the old man who organised the game, told Seong in series one that his son couldn't drink milk.

In series two, there's a scene in which the Front Man offers a carton of milk away because he "can't drink it anyway."

This has led some to theorise that the Front Man is 001's son.

Reacting to the theory, one person commented: "Damn didn’t think there was this much attention to detail."

Another said: "Oh snap…this will be a nice way to tie both seasons."

A third wrote: "Everything makes sense now..."

Responding to someone else, the original poster said the theory "shook me."

But not everyone was convinced, with one person writing: "Too easy. Wasn't there for his death. My theory is that he always took a liking to those that reminded him of his son."

A second said: "Google says 75% of Koreans are lactose intolerant, so it could just be an in-universe coincidence. It's definitely an intentional reference tho."

All episodes of Squid Game are available to watch on Netflix in the UK and Ireland now.
