Many writers have depicted Diana in different personalities and tone; between both of her diametric extremes; that of a worldly warrior, a highly compassionate and calm ambassador, and sometimes also as a naive and innocent person, depending on the writer. What has remained constant, and is a mainstay of the character, is her nurturing humanity: her overwhelming belief in love, empathy, compassion, and having a strong conscience. This trait had been the reason for her induction into the Star Sapphires.
While Diana stood admiring the replica, Bruce Wayne appeared. He proceeds to angrily confront her by grabbing Diana's arm and asking her about the information device that she had stolen. Bruce claims to see right through her "babe in the woods" act, saying that while Diana doesn't know him, he's met "a few women like [her]". Diana, however, calmly smiles and retorts that Bruce has never met any women like her. She then proceeds to tell Bruce that she was unable to obtain anything from Bruce's device, due to Lex Luthor's data having military-grade encryption. Diana explains her intention to re-obtain her photograph from Luthor, stating that she only borrowed Bruce's device, and has already returned it to him shortly beforehand (placing it into the glove compartment of his car), before calmly excusing herself and leaving.
The New 52 universe does not have a "Diana Prince" identity as stated in an interview by series writer Brian Azzarello. However, when she and Superman began dating, for her civilian identity she used the Diana Prince alias whenever she was around Clark Kent; such as when she introduced herself to Lois Lane at Lois's housewarming party under that name.
