After Zachary and Camilla left, Charles returned to his dormitory. Mousie was still outside and had not come back, which suggested that the person tracking him was still not giving up and was waiting.
Without waiting for him to rest for a while, Celestine sent another message: [Charles, you took a break today, right? How about going to Cross Street later to investigate a bit more?]
Charles replied: [No need, I've made some progress here and don't need to go again. You should take it easy today.]
Less than a second after he sent the message, Celestine responded: [Alright then, I don't have anything to do today and I'm quite free.]
Charles understood Celestine's implication, she was hinting at something.
However, he didn't plan to meet Celestine. It was better to be cautious until the situation was resolved. Besides, Charles didn't want Celestine involved, as there could be dangers.
