[Daffodil]

It was Charlie who told the musketeers to get out of jail. It was Charlie who told them not to return to jail (after BB asked them to). Yet he hasn't been punished. And when Rodrigo asked him why he was taking 'their' side, he answered that he was helping them because they were in the sunlight.
His real reason, of course, was that anyone else's bad behaviour makes his own look even better. Charlie is a snake.
