It seems that many people with command aspirations do not have families. Picard didn't.
Almost all captains we know, ended their missions, single but we could have imagined another fate - more happier - for Harry Kim, the eternal hopeful and sentimental guy, who fell in love so easily and jump back on horse quickly after each failed attempt, we met and followed for 7 years.
I mean, after to have spent 7 years to chase the wrong hare, we could hope to see him founding, finally, the right woman, one who would loved him and supported his carrier, in accepting to follow him on the USS Rhode Island.
-> it's not because he saw his mentor, Kathryn Janeway, living a lonely life aboard of Voyager for 7 long years, than he had to copy her lifestyle, using a holo-character to fill his sex life like she did with Michael Sullivan (I can't imagine that Tom didn't talk to him about Janeway and Sullivan).
They were not made by the same wood (family histories, aspirations, expectations, ambitions and personalities).
(Hey, even Joe, the former Voyager's CMO, found his "better" half... though well younger than him and a a bit too much submitted to his egomania to my taste... in the point to think that after a few years of common life, she would have grown up and become fed up with him!)
Anyway, the questions that arise are the following ones :
1) did Harry totally waive the idea to have a (successful) love life to pursue a brilliant carrier or fed up after a lot of one-nighters, he decided to focus his attention and efforts to his carrier, in hoping more success?
2) Could these both souls who were Harry and B'Elena, have fitted on together? And if yes, would B'Elena's presence (and/or even that of a child, like Miral) in his life have changed him, like it was the case for his BFF, Tom Paris?
