I don't think the traitor is anyone we know yet. Off the bat, I have to disagree about the Heart Pirates. Law isn't dumb enough to throw his shichibukai seat to propel a charade. Even if Momo is a sleeper agent, he's eight years old and up against a handful of people more than capable of dealing with anything he does. Other than that, everyone's story checks out. Rebecca and the soldier have motives for going against Doflamingo. The dwarves are too enthusiastic to be traitors (don't ask). I'm surprised you didn't pose the same question about the Donquixote Pirates. How do you know there isn't a mole in their organization? I'm not saying anyone as high up as Diamante or Trebol, but maybe CP8 agent Jora or Commodore Machvise has been under deep cover for ten years or more. Or even a foot soldier like Violet could be a mole. It might be a secondary explanation as to why no action has been taken against him.
