The season's clearest progressive element is concentrated in episode 9, 'Gefahr von Rechts,' which centers on the protagonists investigating a neo-Nazi youth group after an attack on Nina's brother Matteo. The plot incorporates the black sun symbol, school recruitment efforts, and distribution of right-wing music, framing right-wing extremism as a threat that must be exposed and opposed.

This single episode delivers overt social-issue messaging in a program aimed at viewers as young as six. Additional episodes introduce lighter social themes, such as assisting the homeless in episode 1 and confronting illegal toxic waste disposal in episode 13, though these remain secondary to the mystery format. The season adds two new original characters, Jessi and Luis, without any race or gender swaps of established figures. The overall approach keeps ideological content episodic rather than foundational to the premise, resulting in a moderate score.
