GUCCI feels very unsettled. She worries that something bad has happened to SING. He suddenly appears at the KIMs’ and criticizes GUCCI’s radish cake, which she worked overnight to make for him. SING tells ATHENA that MARCO and KELLY have photocopied some personal letters at the office, and LAU KAM sleeps during work hours. SING keeps behaving strangely and seems to be attracted by red objects. All his colleagues interrogate SING about the snitching. He admits that everything is a practical joke. SING tells NG SAU that he wants to cut off all links with GUCCI. SAU asks him why, but he finds it hard to explain.
