Some companions will bring up adoption if you're separate races? That's interesting. I had no idea. I guess I assumed that since Sith "purebloods" and humans could reproduce that a majority of the humanoid races could do the same.
Any examples of a pair that brings up adoption rather than conception?
Vette brings it up in the letter where she talks about having kids. She's uncertain if she can actually bear the Sith Warrior's children, being a twi'lek as opposed to the Warrior's human/Sith/zabrak.
