If you love someone, what would you do to be with them? For Addison Montgomery, it meant she would follow them to the ends of the earth. Which was why she followed her husband to Seattle. But when she meets Meredith Grey, suddenly what she came for and what she really wants isn't the same thing. Meredith is something new, something amazingly, perfectly new. What Addison feels, thinks and wants all changes upon meeting her husbands mistress. Love has a new meaning, dynamics of affairs shift, and biology takes a back seat as Addison finds herself, against all odds, in love with her husbands mistress.
