I Made a mistake: The Keaton's son is named Admir, not Marty. Sorry.
But the AI-names really are "interesting"...my game seems to like old-fashioned German names: this time, the Ursine girl is named Ilse. Ilse is aging much more faster than the Keaton boy (Garbert!), she is now a teen while he is still a child. Perhaps she thinks that she could change her name when she is old enough.
