Thanks for the chapter. Saving her life while also committing to save her grandfather's life is definitely a step up from "he was a little nice to me," but boy does she come on a little strong.
Considering little girls IRL frequently play with baby dolls and pretend to be mothers, I could see a girl her age wanting a child... though obviously folks don't usually explain the process to get a kid when they're young.
Her asking for a child is wild but at the same time:
She's from a family who is all about bloodline. Talks about it & preserving it are day 1 affairs
2. Crime lord is a pretty high octane low life expectancy job. She nearly died literally 3 days ago.
3.As a base having heirs with legitimacy by blood ASAP isn't insane. Keeps succession stable.
4. Obtaining people with crazy lineages seems to be the way to go if grandad is anything to go by.
