That continued to befuddle her: the mixing of genetics from separate realms creating any kind of combination involving the cavities of the two parents. That meant Olivia could have ended up with any pair of Intel, Dev, Still, or Passion Energy, given they were opposite energies. It didn’t matter that her parents were Intelian and Stillian, for Dev came from the Knowledge Cavity just like Intel, and Passion came from the Emotion Cavity just like Still.
That makes sense, but what I do not understand is how she could get both passion and still, from the same cavity.
