Valkyrie
It is safe to assume that she is not born in the next year or two, yes? So there's time. You don't need to rush. I suspect perhaps it's something that occurs. Do you know if it was an intentional birth from a relationship? Or is the rumor I heard of the valkyrie seeking out others solely to bolster their own numbers and return with a child?
Alas, you'll have to wait until we've returned from the mission. Estimates are another day or two.
