Jeong is hiding with several other Exogeni people at the Skyway Weigh Station. He is the only member of the Skyway survivors who knew about the Thorian's presence at Zhu's Hope. After the geth attack, he was aware of the danger of infection from the spores, so he deliberately prevented the survivors from returning to the port. He tells the Skyway survivors that Fai Dan's group is probably dead, and discourages investigation of Zhu's Hope by arguing that the Skyway is too dangerous. Unfortunately, he then realizes that they are effectively trapped on the Skyway, with the geth on one side and the Thorian's thralls on the other. His only recourse is to wait for ExoGeni to send a rescue team.
Commander Shepard's arrival panics Jeong, due to his fear of ExoGeni's secret being discovered. When he fails to discourage the Commander from going to the ExoGeni headquarters, he demands that Shepard be careful when launching an assault on the ExoGeni headquarters — Shepard is not to "damage corporate property" — though Jeong secretly hopes that Shepard will be killed by the geth instead. However, Shepard returns after learning about the Thorian and ExoGeni's role in the Zhu's Hope infection only to find Jeong threatening Juliana Baynham with a pistol. Communications have returned, and ExoGeni is planning to purge the colony. Jeong, having learned about Shepard's military background, is distraught, and the Commander has to choose how to handle him. If sufficiently persuasive, Shepard can effectively defuse the situation; otherwise, the Commander is forced to shoot and kill Jeong in self defense.
