Why the Question Arises
Viewers sometimes question whether cast members have departed due to production cycles, temporary hiatuses, or shifts in episode focus. When certain episodes feature smaller teams or rotating specialists, it can appear that a regular is missing. In Dietzen’s case, sporadic absences are typically tied to shooting schedules, location shoots, or temporary story arcs rather than permanent exits.
