I was just re-watching "Resolutions", and a few things occured to me.
1. Tuvok, being a stickler for protocol, probably should have been wearing a command uniform once he took over as captain.
2. If something had happened to Janeway and Chakotay, Voyager would still have been in good hands.
3. When I saw Janeway and Chakotay return to their formal roles... I felt a twinge of deep sadness, as though something that might have really been wonderful had died.
