Feron told Liara to let him do the talking, which led to Aria teasing her for being unable to speak. Aria said that she would divulge where the Blue Suns are taking the body if they told her why the Shadow Broker is so interested. Liara then blurted out that the Shadow Broker is selling the body to the Collectors, catching Aria off guard, and forcing Feron and Liara to leave.
