These are what we call the 'YMMV items.' Things that some people find in this work. We call them 'your mileage might vary' because not everyone sees these things in the same way. This starts discussions in the trope lists, a thing we don't want. Please use the discussion page if you'd like to discuss any of these items.
Creator's Pet: Gladia. If you didn't like her much in the last book, you won't like her here, no matter what the writer tells you you should. And if the muttered, clumsy justifications under Your Cheating Heart aren't enough to sway your mind, she more-or-less takes advantage of Lije's impaired mental state.
Crowning Moment of Awesome: when Baley, Daneel and Giskard are returning to Fastolfe's home after interviewing Amadiro, Elijah starts to suffer from an agoraphobic crisis in the middle of a brutal storm, at the same moment the vehicle they are in starts to fail. In spite of his terrors, he has enough presence of mind to realize what happened (the vehicle was sabotaged) and to divine Amadiro's plans, so he is able to save the situation by ordering the robots to leave him alone and go to Fastolfe's, and then he has the presence of mind to outright lie to several robots that were looking for Daneel.
Freud Was Right - Played with. Vasilia offers herself (i.e. proposes sexual intercourse) to her father, Han Fastolfe, though she insists that this was because he was the only man she knew up to that point. He himself believed it was natural for her, since he was close to her and educated her on the subject, and for the life of him couldn't figure out why he refused.
Your Cheating Heart: Even though Elijah Baley cheats on Jessie with Gladia, you still root for him because the alternative (Kelden Amadiro) would be a total disaster. Plus he's kind of a Wise Owl to the robots.
