The core cast features Jale and Ramin Dschami alongside Till, Stella, and Pinja, with the Dschami siblings reflecting organic ethnic diversity through Persian/Iranian family names and heritage that fits the port-city setting, including a recurring Iranian grandmother visiting in traditional attire. This casting aligns naturally with the Hamburg context rather than any deliberate swaps of established characters or foregrounding of identity as the point. The season's plots incorporate incidental episodes involving bullying, poaching, flash-mob thefts, corporate spying, and a theft from a refugee clothing donation center, yet these elements function strictly as standard case backdrops without activist messaging, systemic-oppression narratives, or lectures on social issues. The storytelling remains focused on traditional children's detective tropes of teamwork and problem-solving, keeping any light social topics peripheral and free of identity-politics framing or thematic centrality to the premise.
