ANEWAY [OC]: Personal log, Stardate 48546.2. Our journey home is several weeks old now, and I have begun to notice in my crew and in myself, a subtle change as the reality of our situation settles in. Here in the Delta Quadrant, we are virtually the entire family of man. We are more than a crew and I must find a way to be more than a captain to these people, but it's not clear to me exactly how to begin.
Why would Janeway be measuring months in increments of weeks?
The only people that do that are mothers with their babies.
Now this could have something to do with their dog(s)?
Or... Janeway was trying to have children with Mark?
I'd go a step further and say that she was pregnant when Voyager left DS9.
A further step would be to ask if she lost the baby naturally, or terminated the pregnancy because she didn't want to raise a child on Voyager so far from home in front of a crew she didn't feel she could command respect from if she was both a mother and a captain?
