Wbuna was very excited to see this new child looked much more like her than the girls did.
When the twins had been born, Wbuna had been worried. She'd always been taught that Alien traits were more dominant. That was the entire point of the breeding program. Human sims presented the perfect vessel to continue their dying species. While the offspring from tests were still half human, their traits tended to be on the alien side of things, which was the best that the species could hope for.
Wbuna had worried maybe she was... defective when Liliana and Eloisa were born, taking on none of the traits of her parent species. Thinking critically, she'd assumed that it was due to the more natural process they'd been conceived under. That that had skewed the test results her species had.
Now though, she was happy to see her alien traits were strong in the newest member of the family.
