Despite being able to move, Sir Erin insisted that she take the wheelchair to get back to her bedroom. Her knees were weak, footsteps were wobbly- so she didn't complain. Yanarym was naturally lazy, now that there were many people who were her servants, shouldn't she exploit them the best she could?
Especially after taking this rest, she had to go back to the capital and run around everywhere to proceed to the next agenda. That was… make contact with Cain… it would probably take her a whole year to cajole him to like her- not even like but maybe just work with her. But she didn't have that much time, in about a few weeks from today, Caius would be arriving at this kingdom. By then, she had to pay close attention to what was about to happen. She had to play by the plot until she had to escape.
