Jessica Capshaw — Arizona Robbins
"I auditioned for this show two weeks after I had my son Luke, and I was not interested in auditioning for anything because I was interested in being a mother. But my agent called me and said, 'I wouldn't call you for any other reason other than Grey's Anatomy, because I know that's your favorite show.' So two weeks after I had the baby, I... auditioned for Nurse Rose [eventually played by Lauren Stamile]. I knew Patrick because I had worked with him two years prior, so he and I got along real well. But they picked the other girl and I was like, 'Man!' About a year later, I went in for a part that hadn't been named yet, but she was this sexually promiscuous, adventurous part, and I didn't get the role again. That was Melissa George's part, Sadie. They kept saying they really love me and I was like, 'If they really love me, I would have a part in the show." A month later, I got a three-episode offer to play Arizona Robbins."
