I'm pretty sure what Padme did by just trading Grievous back for Anakin on her own accord would be considered treason myself. I'm pretty sure a clone would punch her out. I'm going to guess that the whole incident was somehow just swept under the rug by the Gungans, Padme, and even Anakin. It couldn't be more obvious they are something like a Hollywood scandal. Lies were told and no one besides them will even know. The Separatist's style doesn't seem to be blackmail, probably because this particular plan made no sense. Yeah, it still amuses me with the assumption that all aliens look alike. Really?
