The words spoken by Fisher were naturally heard by the two ladies present, but each received different messages.
Renie was well aware of the conversation Fisher had with Old Jack in the tavern earlier, knowing clearly that Old Jack did not inquire about his future movements. But that was just the surface logic that made sense; what she truly cared about were Fisher's later words, as they held the real meaning within them.
Firstly, Renie and Fisher had been separated for a long time. During his time in Nali, when he was severely injured and had enemies everywhere, forcing him to flee, it was Alagina who helped him. Even if Alagina might have had her own ulterior motives and small purposes, Fisher could not forget the kindness she showed him in his time of need.
He was telling Renie that he must provide an explanation to Alagina, which was the true reason he sent a messenger to her.
