Amber Volakis appears in the second episode of the 4th season, when Dr. Gregory House begins to form his new team to help him conduct differential diagnostics. Having recruited a large number of candidates, House then filters them out for various errors and violations, so that in the end there are 3-4 most suitable ones.
Amber Volakis receives #24 in this "competition". Starting from the very first medical case, Amber proves herself to be both a good doctor and a good "manipulator".
