Yang Yi needed to make contact with the janitor, but the intermediary he required now wasn't quite effective anymore.
Who then? Of course, it was Bonnie.
Yang Yi hadn't seen her for quite a while, as it was inconvenient for him to meet Bonnie again now. Since the Grey-cloaked People had already discovered Bonnie's true identity, although Yang Yi could still reach out to the janitor, he would surely try to choose a method unknown to the Grey-cloaked People.
If Yang Yi couldn't contact the janitor through Bonnie, he would need to find another reliable liaison, but the problem was he didn't have one now—no one he could easily contact and meet.
Like John, the FBI's crime investigation expert, Yang Yi definitely couldn't discuss anything related to the Grey-cloaked People with him. Why not? Because John wasn't qualified enough.
