So Kiaver goes in - it's really something to watch her go through that door, which otherwise looks pretty human-sized - and then comes out and says Kithabel doesn't find her mesmerizingly beautiful but is willing to behold other dragons under the same conditions.

Dragons march past Kithabel into their own world.

Kithabel does not find them mesmerizingly beautiful. Pretty, yes, but not mesmerizing.
