Dr. Ethan Haas says, "You know how, in that Wizard of Oz movie.... that girl, Dorothy, how she goes on this amazing adventure that's all in glorious Technicolor, right? And then she ends up back on the farm in boring black and white. That's how it was with this woman. Before her, I knew exactly how my life was going to go. And then I met her, and suddenly I could see a totally different future for myself. In color. Once you've seen Oz, who wants to go back to Kansas?"
