Luo Yusu didn't immediately confine Lin Xiao; he and Zhou Wenqing had just returned and needed to handle some matters.

Midway up Zixiao Peak, there were two adjacent courtyards where Lin Xiao and Zhou Wenqing lived.

Zhou Wenqing arranged for Yuewu to stay in her courtyard and then went to find Luo Yusu, seemingly not planning to return tonight.

The master and disciple hadn't seen each other for a long time and indeed had much to talk about.
