I respectfully disagree with changing all of the "Torres" references to O'Malley.  This has been discussed on the Grey's Anatomy and List of characters from Grey's Anatomy talk pages, although it hasn't been an issue on this article before.  Several characters have casually referred to the couple as "The O'Malleys" and Callie as "Callie O'Malley", but professionally and probably legally (despite the soundtrack of the most recent episode"My Favorite Mistake") she is still Callie Torres.  Her medical license would be in the "Torres" name, so until and unless she went through the arduous and long process of changing it, she would have to practice medicine as Callie Torres.  There is certainly precedent for female surgeons retaining their "maiden" names upon marriageMiranda Bailey's husband is a Jones, and even Addison hyphenated her last name prior to her divorce.  In addition, Callie's labcoat in "My Favorite Mistake" still reads "Callie Torres M.D."when Addison's character name changed to Addison Montgomery, she also got a new labcoat.  Callie seems to still be using Torres, aside from the casual "Callie O'Malley" nicknaming.
