Samantha Who?:

Sam's friendship with Andrea becomes compromised, once Sam asks Andrea for help in finding an aid to help her out at her new job. After Winston hires her to head his charity foundation, Samantha evetually hires Andrea to be her vice president of legal affairs; Dena, hoping to be a bridesmaid, offers to help Andrea with the wedding plans.

Sam realises she has made a mistake in hiring Andrea and soon meets someone who is far better qualified and wants to give them the job instead. But when Andrea refuses to leave the job and makes Dena her Maid of Honour over Sam, Sam gets her own back by refusing to relinquish her Maid of Honour role.
