'Lian's First Time' is a bonus mission in Syphon Filter: Logan's Shadow which introduces the relationship between Trinidad and Lian Xing. It is where the latter performs her first assassination on Qwan Tak, governor of Altay, Mongolia, while the former provides overwatch and supervises her.
When the mission starts, Lian radios Trinidad, telling her she is close to the insertion point. She is told to lower her voice since the guards are close, and does so. Lian is told that although she was top of her class, there is nothing to test agents like their first mission. Lian tells Trinidad she is near the power line and the guards can see her. Trinidad responds, telling her she has line of sight to the south patrols.
