"SO, CAN YOU share the bad news now, Mon?" Calleous opened up after a long while of walking.
Since they came out of the cafe, the two of them had been walking aimlessly, with Calleous only following after Amon while the latter took the lead in walking around. As they continued walking, Amon did not forget his role as the tour guide. He keeps on introducing shops and places to the unfamiliar Calleous.
On the other hand, Calleous didn't feel anything and just went with the flow. He knows that whatever Amon will tell him might be a sensitive topic to be discussed naturally while being surrounded by many people.
So he just goes with the other's shenanigans. Calleous knew as well that Amon really planned to share it with him. The other might just be waiting for the right place to share it with him.
