I love Maddison because Maddison is an amazing couple just like Derek and Meredith. They have dealt with so much as a couple. I loved their scenes together in "Yesterday" plus I feel like they are a great couple. I feel like the moment in "Oh, The Guilt" where Mark tells Addison that her angry divorcee thing is sexy was great. Everytime Mark and Addison have sex, I loved watching them together. I wanted Addison to leave with Mark when he told her that Derek loved Meredith and not her. "He doesn't love you. He's in love with that intern." I believe that Mark and Addison's relationship was a great relationship because they really love each other so much. I didn't understand why Addison didn't come clean with Derek about her and Mark's relationship until after their divorce became final. Mark loves Addison just like Derek loves Meredith. Mark called Addison "the woman he loved" just like Derek calls Meredith "the love of his life." Mark and Addison's relationship progressed as something more then they thought.
