The Doctor began referring to Clara as Clara Oswin Oswald as soon as he knew her middle name. That's what he called Victorian Clara at the end of "The Snowmen" and what he erroneously called Clara in "Bells." He mirrored this at the end of "Bells" with the omission of "Owsin" after having learned that Oswin was not the middle name of this Clara.
