Ok, you conveyed it. However it should had been clear Ruby and Cerulean will stay in the city, Silk has likely arranged a escort for them to get to her brothel along with other children. As in her manse they are relatively safe (although neomah's need to continue attend guests and customers as usual but they know the girls/children are off limits). If Sanger would ask why it's arranged so, Chorgath would had told Sanger that Ruby and Cerulean are demons, or rather mortals turned to demons more precisely.
