Having George in the advanced classes didn't change their atmosphere. The Princess' presence always filled the lessons with faint tension no one could ignore. Khan's relationship with her had improved, but even he had to remain polite and distant in public.
Things obviously changed whenever the group returned home. The atmosphere in George's flat was always cheerful, and Anita soon got a piece of that. Ron could only praise another well-mannered descendant, so she had no problem joining the Princess.
The week went by quickly. The immense amount of homework kept everyone busy, and Khan had it worse than his peers. The Princess, his studies, training, and relationship harshly affected his sleeping hours. He had to wait until after his flying lesson to get any decent rest, and even that was short-lived due to the trip.
