Origins of Purple Quiddity?

[Schroeswald]

I think he might have been referring to the fact that each inherited a trait from the non-custodial parent as well (Elan got his dad's penchant for narrative, while Nale inherited his mother's obsession with overly-complicated plans.)

Of course, we can't know whether this implies anything about Lamarckian evolution unless we confirm that those traits didn't exist in previous generations. It's quite possible that Elan is only the most recent sequel in a franchise stretching back to the creation of this world.
