If we assume the Patricians growing interest in the crossword puzzle lady, along with the surprising risks he has been taking, is a sign of growing instability, what would happen if he became too unstable?

Since this is all hypothetical, you can't be wrong.
However, you can be questioned. Be prepared to defend your stance, and also be prepared to look at other people's ideas with an open mind.
