Back at the station, the sergeant reprimands Yuk Bo and asks her to reconsider her decision to be a policewoman.
To cheer Yuk Bo up, her teammates decided to have an impromptu BBQ party at Pak Kiu's place. Yuk Bo is surprised to see Fa Si Lai there. It was then that she knew that Fa Si Lai has been working as a housekeeper all these while.
Yuk Bo rushed out from the house and Pak Kiu runs after her. She goes to the pier and dives in. Pak Kiu dives in after her to help her. Yuk Bo then confides in Pak Kiu and Pak Kiu promises to help her be a better policewoman.

Laughin told her that Hau Ko may have started to plan to revenge on Tin Ko since two years before and may even intentionally arrange for Chung to be Tin Ko's driver.
Laughin advised Sam Jie to go to Taiwan to investigate further. He offered to accompany her but Sam Jie declined, saying if they both go together, Hau Ko will be suspicious.
Hau Ko and Laughin were together in the car when Hau Ko discovered the hidden recorder. Hau Ko confronted Laughin (with a gun to Laughin's head) and Laughin confessed that the recorder was planted by Sam Jie. Laughin pleaded with Hao Ko and said he will help Hau Ko to be the new leader.

Sam Jie returns to Hong Kong and is surprised to learn that Tin Ko's urn placing ceremony is over and no one informed her about the change of time. Her name is also not carved on the marble as Tin Ko's wife.
Back at Chun Hing, the triad elders questioned her loyalty to Tin Ko and accuse her of wanting to become the new triad leader. However, Hau Ko protect her and inform the triad elders that he is the one who asked Chung to look for Tin Ko two years ago. Hau Ko said as Chung has many enemies in Taiwan, it will be better for him to be in Hong Kong after his release from prison, so Hau Ko asked Chung to look for Tin Ko to get a job.
