ACTUALLY! The transformation thing in this particular ep just brought another question to my mind: how does the stinky jacket fit in with "what happens to Shen Wei's day clothes when he transforms into the Envoy?"

I've seen people make a convincing argument that he can fix his clothes as he materialises and dematerialises them, but if he could rematerialise them in a fixed/clean state, surely he wouldn't deliberately go for bringing back the smelly blood?
