Eric Dane is my second favorite actor on Grey's Anatomy because Mark is my second favorite male character not to mention that he is hot and sexy. I also love Grey's Anatomy mainly because of Eric as Mark and Kate Walsh as Addison. Even when Eric plays Mark as a manwhore, I still love him. Eric has amazing chemistry with Kate Walsh. If and when Eric does leave the show, he will still be my second favorite actor on Grey's Anatomy and Mark will always be my second favorite male character. Eric Dane has does an amazing job as Mark over the past four seasons. I cried when he told Addison he loved her until Derek who loved Meredith and Eric played that scene well. I think it's one of my favorite scenes that Eric has done as Mark over the years. Eric Dane is and will always be my second favorite actor on Grey's Anatomy just like Mark Sloan is and will always be my second favorite male character on Grey's Anatomy.
