Just like how Clementine could not stop Tang Shaoyang from creating the mission, Tang Shaoyang could not stop her from following him too. They had the same authority, and Clementine could cancel the mission with her authority. However, she knew it was useless because Tang Shaoyang could create the same mission. Instead of playing a childish game like that, Clementine chose this way, joining the mission to ensure the new Executive Administrator's safety.
Clementine did not look down on Tang Shaoyang's power. She was aware of how strong the man was, but she had experienced the fight against the Void Cult. If the Void Cult had created a meticulous plan to kill Tang Shaoyang, they would have succeeded. She almost died countless times in the hands of the Void Cult, but her experiences saved her from them. On top of that, she had been in this position too long, and she had an ideal built for her class which she believed made her stronger than Tang Shaoyang.
