Emma is the opposite of her sister Kitty in almost every way; she is a no-nonsense, highly motivated law student and takes the competition very seriously. After being dumped by her ex-boyfriend Jake, Emma finds it hard to trust anyone and refuses to team up with any teams, even if said team are the among the nicest of people or are not the kind who would betray them. She sees her sister as a liability to her throughout the Race and does not let Kitty participate in challenges, even if Kitty is successful. Being a competitive-freak, Emma denies her faults and blames her sister or anyone else on several occasions for any mistake she has made. As the Race progresses however, and after she experiences new love, Emma realizes that winning isn't everything and starts to cherish her sister's effort, in addition to warming up to the other teams. Though she tends to be more level-headed than her sister, Emma acts differently when it comes to her love life, showing signs of obsession and begin to think on how she and her partner would spend their future together, which according to Kitty, was the reason Jake broke up with her.
