It’s bugged me a little in previous episodes, but in this episode it really bugged me that the entire medical staff seems to be M’Benga and Chapel - I know it’s normal for Trek for the staffs to appear small but normally either it’s been a plot point (Voy), others mentioned if not seen (DS9) or that we occasionally see them (TNG, DIS, TOS). It’d be nice just to see a few others about.
