I think that Jim meant 'a fraud' in as much as he played the game by not rising to Linda's bait. [Luisa's too for that matter]...because I believe that in the 'real world', if Linda or Luisa had taunted and goaded him like they did in the house, there would have been real fireworks coming back at them from Jim in retaliation!...as Jim himself has told us on several occasions..the whole point of him being in the house was to change the public's perception of him!...And to do that he donned the 'calm and perhaps a tad too-reasonable persona' ..and generally bit his tongue during the two dragon's bitch-attacks on him, which he was all too well aware were designed to get him to appear the "angry misogynist that is capable of being a real life Bill Sykes character"!...So he feels a fraud because he mastered his compulsion to 'give it back' ...simply to win the public over!
Well done Jim...I couldn't have done it...I would have strangled Linda with Luisa's gizzards, and been evicted to great boo's , pretty sharpish!
