Kate Walsh is my second favorite actress on Grey's Anatomy because Addison is my second favorite female character not to mention that she is so beautiful. I love Grey's Anatomy mainly because of Kate as Addison and Eric Dane as Mark. Even when Kate played Addison as a girl whose husband was still in love with his ex-girlfriend, I still hated her. Kate has amazing chemistry with Eric Dane. When Kate left the show, she was still my second favorite actress on Grey's Anatomy and Addison was still my second favorite male character. Kate Walsh did and still does an amazing job as Addison over the past five seasons. I cried when she didn't go with Mark even after he told her Derek was in love with Meredith and Kate played that scene well. I think it's one of my favorite scenes that Kate has done as Addison over the years. Kate Walsh is and will always be my second favorite actress on Grey's Anatomy just like Addison Montgomery is and will always be my second favorite female character on Grey's Anatomy.
