It was a good episode. I was half the time unsure whether Lyuze was just dreaming of getting rusty or whether she really was beginning to get ruined. But I guess at least the piece falling from her neck was real. The hand probably wasn't as it was shown a few times, as if by purpose, after the scene and it bore no marks.

The relationship of those two certainly countinue pretty rough. It makes good scenes, though, when Lyuze seems to want to touch Casshern but is only able to when she forgets to keep herself in check, and then when she notices, she always jumps back like from an enemy. And Casshern certainly has no clue of what's going on.
