Just watched the trailer. The number is definitely there. Though it appears after a clip of the main character describing his childhood as ‘unusual’ then showing his father, (one of the main Neo Nazi characters from the series Oz, Lee Tergesen) being paranoid abusive and reclusive.
So I’m supposing that the main character is raised by a White Nationalist Prepper and that’s the reason 1488 appears over his name. Spending the series trying to help people and deal with the indoctrination.
