There is little doubt that The Man in the High Castle Season 4 will be the most exciting season for the Amazon Prime series. After all, fans will finally learn how it all ends for Juliana Crain, who has spent most of the past three seasons looking for a way to save her own universe, and John Smith, who seems destined for greatness. But will the final season prove to be a vulnerable one for Inspector Takeshi Kido? There is a huge possibility that the Kenpeitai leader's only weakness will be revealed this November.

Inspector Takeshi Kido is undoubtedly one of the strongest characters in The Man in the High Castle. Although most people view him as a likable antagonist, some believe that Kido is more of an antihero who will eventually show his vulnerable side. Since Season 4 is set to be the show's final season, there is a huge possibility that fans will finally learn more about Kido and what truly makes him tick. Interestingly, actor Joel de la Fuente may have confirmed this as he discussed the upcoming season.

Joel de la Fuente had previously shared a brief video on Instagram where he discusses what fans can look forward to in The Man in the High Castle Season 4. The Hemlock Grove actor confirmed that there would be major changes about his character in the final season as Kido begins to show the truth about himself. In addition to that, de la Fuente teased that there will be "a lot of personal aspects" to Kido in the upcoming season. This could mean that Kido could finally reveal his only weakness.

In the video, Joel de la Fuente also confirmed that The Man in the High Castle Season 4 will introduce an unexpected character. It was revealed that Kido's son would finally debut in the final season. In his post, de la Fuente shared that his character's son will be portrayed by Origin actor Sen Mitsuji. Interestingly, there are brief moments in the video where the new character is shown interacting with his father.

The name of Kido's son was not revealed, but it appears that the Inspector truly cares about the boy. Could Kido's son end up being his downfall? Or will the character make Kido even stronger? Everything will be revealed in the next month.

Are you ready to find out about Inspector Kido's fate? The Man in the High Castle Season 4 will premiere on Amazon Prime on November 15.
