Clips at the series three press launch have shown Simm and on the Newsround report on the 22nd March show Tennant and Simm both referred to the character as 'Mr Saxon', but Tennant also goes onto say that he's 'more than a match for the Doctor in ways that he can't imagine'. Tennant hesitated before saying 'more than a match...' as if he was searching for the right words.
