When he became an eight year old, Jan became a top hunter. He'll crush the eggs and whack trees. His emotions are so swinging severe that there aren't any cures for his hereditary complex PTSD, which means that it runs in the whole screwed up family.
As a twelve year old, Jan will have to wrestle with various animals in order to get food. Even as Chicma is dying, she'll have to be sacrificed by him on the day her brain stopped working.
