Powers and Abilities
Chelsea is gifted with the supernatural talent of influencing the emotional ties between people, either by weakening or strengthening them. Aro, one of the Volturi leaders, used her gift to keep Marcus loyal to the Volturi after Didyme, Aro's sister and Marcus' wife's, death. Due to the importance of her gift, Aro thinks of her as one of the high ranking members of the Volturi, along with Jane and Alec and uses her as a secret weapon to disband their enemies and binding wanted people to the coven.

Chelsea's main occupation is to distance the innocent emotionally from the guilty by severing the bonds that are shared. Also, when a vampire that Aro is interested appears, she secures the ties of that vampire to the Volturi, prompting them to serve willingly. Eleazar suspects that Aro had been using her power to make the Volturi guard co-exist easier, as well as strengthening their willingness to obey the leaders.

However, her power has a few limits; as stated by Eleazar, she cannot as easily influence the emotional ties of people that are stronger than friends or acquaintances, and in a normal case, even those who think of each other as family. She could not have changed the way that Bella Swan and Edward Cullen felt about each other, for example, or the ties between a true family. When she is not around those whose bonds are tied by her power, her influence will not fade immediately; rather, it wears off over a matter of time depending on how long a person has been exposed to her power before separating from her.

Also, though she can influence these ties, she probably doesn't have the power to see them. This is supported by Marcus's ability to read emotional bonds between people and the fact that Aro does not surround himself with second-best gifts. If she could see them in the first place, he would not have needed to keep Marcus in the coven. Her power is also the main reason Caius had not attempted to overthrow Aro.
