Yuksuen, in her capacity as Tingtong’s colleague, once kept a close watch on Tingtong. She noticed he was a loner and also knew he was undergoing an internal investigation. While Sukmui is looking at Yuksuen’s notes which Yuksuen wrote when she was a decoy, Sukmui has no idea who is the sender. She also does not know how to ask Ting-tong about past events. Ho-yeung describes those days when he is growing up. His relationship with Ah-hei progresses further as he is encouraged by her. Ching-chik uses some method which he has learned from Ka-keung to play football. Hop-sing tells Ching-chik to stay away from Ka-keung as he reckons Ka-keung has improperly taught Ching-chik. Suk-mui has stolen Kei-gee’s Id. She pretends to be Kei-gee and interrogates Wing-luk’s minion. She also covertly captures their fingerprints. Ah-hei asks Ho-yeung to come to some herbal tea shop which he has mentioned. But the boss turns them away. Ah-hei then realizes the herbal tea shop belongs to Ho-yeung’s parents.
