Other side of the sister?It's another case where DSC excels in consistency by highlighting inconsistency. Klingons always look different; DSC stays true to that. The thing darkening the skies above Shi'Kahr either is there or not; DSC supports the ambiguity in full. Spock is emotional or stoic, in DSC just like everywhere else.
What I worry about is the fate of the third body in the setup. It's there between Vulcan and this visitor in TMP. It's there again in "Lethe". Where is it in "Unification III"?
