For once he was pleased that no one he had met on this planet had recognised him. It was not because he was caked in mud and other people's blood (he had long become used to the smell and feel of dry blood). It was more because, like so often now, despite the exterior of fearlessness, behind the dark robes, is a man shaking with fear.
It is even worse when he is on leave (he no longer has a strategy to plan or a battle to win or a ship to fly) and when he comes home to Padme (she just doesn't understand). He doesn't tell anyone (there would be too much to tell and too much to relive) and so he just stays silent.
Padme tries to coax it out of him but in an attempt to avoid the question he kisses her on her lips and then for a while the shaking of his hands stop and only the smell of her skin, her hair and her kisses are real (though he knows that as soon as this is over the shaking will resume).
Looking up he sees for a moment a flash of blue and white head tails and orange skin disappear behind one of the buildings and for a instant he thinks it is Snips (though deep down he know it isn't) and for a while he stands there lost in thought as if by thinking it will bring Snips back (he knows it won't though).
So he stands there for a while until Rex comes over and asks him of he is OK to which he says he is (though both know he isn't) and if he wants to come to medbay to get cleaned up (he does as it mean he will to be able to try and scrub the experience away) and so they walk away.
Even after he has scrubbed the mud, blood and the sight of the blue and white head tails away, like a ghost they linger on. The stain will never truly come out.
