Ame also has fourth wall powers, and Terra's story seems intertwined with Lin's rather then Radomus.
About Radomus the chessmaster. Chess is in essence a very cold game, only slaying the king counts. The fact that he applies it to his real life problems is scary. I can get the cheeky comments and metafors but making the personal comment "I'm playing black this time" when gardevoir is captured does lead me to believe he actually does think in it. Remember everything but the king is disposable. Also by allowing the El to be this close, strongly suggests that Luna is not the king because if Luna was king then he would have placed himself in check or in layman terms, the risk is too great. Gardevoir is also most likely not king as well based on a interview. So what is his 'king'? Himself, doubtly. It might either be his dead wife/soulmate or a greater cause. The dead wife might explain his ties to team meteor: new world, revive wife, you know the drill. The question is then what event made him a turncoat?
