Some of Rachel's backstory is revealed. She believed the tower was calling for her, but when she arrived Headon tells her that the tower did not call her at all and that she is too weak to enter. Desperate to become special, she begs for any kind of chance. Headon holds her immobile and she watches as Bam arrives and is able to defeat the first test. She is jealous of Bam and wants to be special. Headon gives her a special test, telling her that she will be allowed to climb if she defeats Bam with her own two hands. She demands a special weapon (since Bam was given an amazing weapon in front of her) and Headon gives her a bodyguard that will die in her place once, allowing her to essentially have 2 lives. She makes her way through the tower knowing that she must kill Bam but unable to bring herself to do it. She becomes more and more jealous, urging him to stay away from her in her mind. She is told that if she waits long enough and follows the signs given, she'll be given a chance to kill him. So she allows herself to be taken by Hoh and uses the bodyguard to die and return. She waits until Bam is injured then pushes him into the Shinsu lake to kill him. When the others find her alone, they ask where Bam is and she says the bull came then passes out. Everyone assumes Bam is defeated and decide that as a favor to him they will help Rachel reach the top. Rachel, resting in her room after the trial, laughs wildly then covers her face--conflicted over what she's done but still determined to reach the top. After everyone leaves for the next level, Bam wakes up in a deep cavern badly hurt. He remembers Rachel pushing him. He decides he needs to climb to tower in order to find his own answers.
