Deadly Chess Game

"What makes you think that the traitor is still nearby?" Keiko asked. 

"The sonar device's area of coverage is very limited, so this person couldn't be that far away from us. She must be with the team that was stranded outside the city. I have already confirmed that Elisa Ford killed two soldiers and escaped. I doubt that she could escape that far in such a period of time. Also, I've checked using the life detector and got no response. It means that she should be dead by now," Jeanne elaborated her guess to Keiko. 

Keiko wasn't that surprised by Jeanne's explanation.

She realized that there was indeed a traitor in the team and that the traitor was someone who was very familiar with the third squadron's convoy arrangement.
