Bank on it.
I've been having serious doubts about nadin's cerebral capacities for quite a while now; it
is possible the way she uses that particular resource, she's actually stupider than Beth.
Her "knowledge" of history, for example, is more "ideology" than pure history.
She's a discredit to all the cerebrality of those from whom she derived, a discredit to her race, being the way she is.
