Oh they insisted on how Luke is was a perfect copy of Asch, down to the last details.
They kept repeating it.
However they're wrong.
He's not a perfect copy:
-He didn't possess anything from Asch personality or memories
-He may have a dark future if his formicry transformation fails as in the first "tryouts" meaning the copy has a defect somewhere, meaning he's not a perfect copy.
So at the time Asch was copied Luke was already different, and the difference grow stronger as time passes.
Animation quality really did drop this ep. Nothing interresting too.
