Claire has been demoted from the Control Section to the Debris Section, where she replaces Hachimaki and is trained by Tanabe, who is upset about Hachimaki's absence. Cheng-Shin forces himself onto Tanabe, claiming that she should leave Hachimaki because he wants to be alone. Hachimaki and Hakim join two other candidates in the second round of tests, where they are isolated in a pod for ten days, and they must assemble a model of the Von Braun before they are released. However, the main power unexpectedly goes out on the last day, jeopardizing the isolation pod's power and air supply. The air supply will only last for three people, so the four of them must think of something to survive. Hakim considers killing one of them to save the rest. After the test is over, the rescue squad realize that the four lowered their body temperature to minimize their oxygen consumption, allowing them all to survive. (Source: Wikipedia)
