This inclusion of characters like labor contractor Chang and crew leader Tao aligns directly with the historical record of immigrant workers on that project during the 1860s, rather than serving any contemporary ideological agenda. The season also features the original character Mei, who disguises herself as Fong to join the railroad crew, integrated into the narrative as a period-appropriate survival tactic amid the harsh conditions of the era. The storytelling prioritizes classic Western elements such as labor disputes, personal vendettas, and the drive to complete the transcontinental line, without overlaying modern social justice frameworks or systemic oppression themes.

There are no instances of race- or gender-swapping established characters, and the creators have not issued statements promoting activism or diversity initiatives. Episodes portray events like worker strikes and cultural observances such as the Tin Hau festival in a straightforward historical manner, resulting in a season that maintains its entertainment focus on frontier expansion and individual resilience.
