Carmen was used to cleaning up Andrew and his wives' mess in their room every day, so she didn't even flinch when Andrew asked her to clean the office.
She was not new in this business, you have to remember that both she and the other older maids were already working in this place before Andrew bought it, of course, they were slaves before.
Andrew decided to go to the dance room to check on the dancers while Carmen cleaned the office. Although Andrew had forbidden the dancers to practice in the evening hours, these girls always met in the dance room to discuss the upcoming day or listen to Helena with any direction or comments.
When Andrew entered the dance room he could see the girls gathered together talking and laughing. They weren't talking about work or anything like that, they were just having an idle and carefree chat, they were just relaxing.
