46화: 레슬이 크란켄 박사의 심장을 받아들이면서 어둠의 면이 발동하고 조와의 대결이 시작된다.
Dr. Kranken disguises himself as a shopkeeper, and gives Rachel a heart so she can feel emotions. At first, it seems innocent enough, but the doctor's real plan is but to awaken the dark side of her. She eventually goes berserk, saying she hates Joe, leading to a showdown with Joe at a baseball field. Her evil side reveals anger for wanting the heart destroyed, but Rachel eventually surpasses the heart's evil, saying she can act on impulse and wants to be with Joe. She smashes it and sends it hurling back to Dr. Kranken in the shape of a baseball, with a home run swing from Joe. When wondering how his plan failed, Sprocket tells Kranken his heart doesn't understand emotion. Meanwhile, Alastor refuses to partake in anything but defeating Joe. (Source: Wikipedia)
