Episode 16 - S1.E16

When LEUNG and CHUNG learns of PO's plight, they rush to help him and arrange to smuggle him to Taiwan. KWAN discloses MING's real identity and TIN forces PO to kill him. PO only wounds MING and later risks being caught when he sends MING to the hospital for treatment. In the end, MING's life is saved but PO is put to jail. PO suspects that KWAN has betrayed him and he asks LEUNG and CHUNG to collect more evidence about KWAN's evil plot. They then reveal KWAN's evil deeds to TIN who also grows suspicious of KWAN. During the interrogation, KWAN makes all sort of excuses to cover up his evil deeds and he even urges PUI to admit that it is she who provides MING with information concerning their trade. To prevent PUI from disclosing the truth, KWAN kills PUI. This leaves the gang with no choice but to believe in KWAN.
