Ye Shuang and Cedrick were both silent but for different reasons.
After returning to the apartment, the first thing to settle was the accommodation problem for Su Zheng and Cedrick. Staying at a hotel was out of question; the sensitivity of these two's identity was as high as Ye Shuang and Han Chu's. That was especially so for Cedrick, who was a high-profile target within China. Even though the case that he was involved in had been resolved at light-speed earlier.
However, it was not going to work for them to stay close to Ye Shuang. One, it would be too easy for others to connect them together, and two, it was hard to find another two empty rooms in that building.
