Caris has spent the musical interlude considering his situation.
It's not that he can't be more forward. He doesn't particularly care to, as a personal quality, but this here is a competitive sport and winning is enjoyable regardless of what you're winning at. The problem is that he doesn't, in fact, want to do exactly what the Emperor's lovers always do, insofar as he can even guess at that, and he does not in fact want to leave the Emperor entirely satisfied and pleased with himself. You don't get married if you already have all the things you want from someone.
And it feels like there's - something missing here, something more than the Emperor preferring to be lazy while other people make themselves busy pleasing him, which is an entirely normal preference. This feels like a test of some kind, and he hates failing tests, and he's not sure the answer is to do what presumably every single other person in this position does. He has advantages over them. He's safer, more valuable, has more powerful magic, can take a lot more punishment though absolutely no one on this stupid planet seems to appreciate this despite how it's obviously one of Carissa's better qualities -
- what does that get you? Nothing, without the answer to the question 'what does the Emperor want'. What the Emperor wants quite obviously includes Caris figuring out what the Emperor wants without being told, and doing it without being ordered. Maybe the test is just how much research Caris put in -
- but again, it doesn't feel like that. It feels like the answer isn't one that boys often come here possessed with.
