Amber Volakis was one of the applicants for the fellowship positions that opened up in Season 4.
She was first called by her assigned number, 24, and then later by her first name, she was usually referred to by Gregory House as "Cutthroat Bitch" due to her manipulative nature. Despite her failure to obtain a fellowship position, Amber remained a potent force in the series well after her dismissal, and even after her death at the end of Season 4.
Amber becomes the patient in Wilson's Heart, where she experiences multiple organ failures as the disease progresses.
The cause is revealed to be amantadine poisoning, as her kidneys were destroyed by the crash and she was unable to process the medication she was taking for the flu - amantadine was left to circulate in her system for more than a day, damaging all major organs, and making her ineligible for transplantation in the process.
Amber was one of the forty applicants who were fighting for the available fellowship positions in The Right Stuff.
However, she revealed to Jeffrey Cole that she was still doing work at her old job while she competed for the new one.
He realized Amber would be the best choice because she wanted the job the most and wouldn't let him die.
In addition, the men won by default when although Thirteen got the diagnosis right, the women’s team failed to ensure the patient was treated properly and House fired all the women except Amber and Thirteen.
She was quickly identified as the most ambitious candidate when she was assigned along with nine other candidates to wash House's car while twenty others were running tests.
She quickly mutinied and took eight others with her with only Cole staying behind to do the work.
However, she returned fifteen minutes later to rejoin Cole and took the car to a car wash.
She aggressively made suggestions and even broke the rules to keep medical records on the patient on her PDA for easy referral.
She had a similarly tough time in Ugly, particularly when it appeared Samira Terzi was going to nab one of what appeared to be two remaining spots.
