Alita simply introduced Quera to the rest and let her get another room for herself while she deals with her business.
As she had a lot to do, she left Quera to Zara as Zara was practically the leader of her partners on Eartha and she understood her operations very well.
Although Alita was planning on making Quera an official wife, it didn't mean that she should throw air when facing her concubines. They all should treat each other fairly and be like family.
Zara thought that Quera will act pompously but was glad when she saw the other's attitude. It made the three of them very relieved as they didn't want to have their backyard on fire.
To be honest, Alita didn't have much to do in this life apart from making money and increasing her family as her dream was still there.
