The two youngsters chatted merrily the entire time, which was made much more enjoyable by Amy's refusal to bring up the subject of Lucas. Amy knew that the more she brought up the subject, the more suspicious she became, so she just let it go.
When they arrived at the mall, the two girls exited the car, and the driver drove away. Arianna didn't feel threatened because she was aware that she had guards following her that Amy was unaware of.
Paulo began training guards before assuming the mantle of Duke in order to fully protect his family. Arianna had no idea that guards were always following her wherever she went, and this could have remained a secret if the new Arianna hadn't sniffed them out with the help of the system.
Outside, she had no trouble moving around because she knew that some individuals had promised to protect her and would go to any length to keep her safe. If Amy is up to something nefarious, those people will emerge and deal with whatever is going on.
