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
