This is just a small detail... but still this 'quest' can seem a bit 'not worked through' under some circumstainces. I am writing this in regard of Astarion story and romance as I have tried visiting Zethino after finishing The Pale Elf quest. In my story Astarion did not ascend, killed Cazador, got his revenge and had this new goal to 'live', since he is finally free. Yet after coming to Zethino, the answers are still the same like they were if you take the test before meeting Cazador. His greatest desire is still revenge. It would be really nice if someone thought about this and changed the answers in consistency to the story. But I guess, it is possible that nobody even thought of the possibility, that the player will visit Zethino after the Cazador confrontation, since it happens in the Lower city, where the player still might not have access, when they first encounter the circus.
Anyway, it is just suggestion it might be more immersive if even this small encounter would take into consideration the players choices.
I can imagine the ascended version of Astarion could crave to rule over the city (or even the whole world). And also the other companions - I have not done the test with anyone else, so I do not know about their correct answers - but I can imagine, how the answers would be different depending on the player choices. For example Shadowheart which killed Nightsong vs Shadowheart which rejected Shar. Can someone confirm if her answers differ based on this choice? Or the other companions...?
