How many times do I have to repeat myself? Jeri Taylor created Kathryn Janeway. Jeri Taylor wrote the novel Mosaic. Jeri Taylor told us in Mosaic that Kathryn Janeway first met Tuvok after her first mission as a captain. She was repeatedly addressed as "Captain" by rank and it was repeatedly made explicit that she had been the captain of the ship. That is the intention of the woman who created the character. What the hell more do you need?
I'm confused. What are you getting at?
