I just made a whole topic of "What is the idea forum for." Christ, why do I bother.
Also I appreciate all the people speaking for me while I'm on vacation. You da real MVPs.
I'm pretty sure I've said this before, but (basically what you said)... Reaha's definitely an NPC I think would work well as a mother. Unlike Anno, who's career-oriented, or Saendra who's likely to blow herself (and quite possibly you) up at literally any moment, Cured Reaha's actually... a pretty stable and safe person, who doesn't have a lot of demands on her time (assuming you're taking care of her), leaving her in a good position to dedicate herself to motherhood. Having her get pregnant would probably necessitate moving her off the ship -- I've explained before why having pregnant women about a combat starship is a Very Bad Idea(tm) -- but now that the nursery exists as well as the ResDeck, it's not like she'd be vanishing off the face of the earth.
Honestly I think Reaha'd be a pretty good mom, especially if she has the PC and Briget to support her.
