This Ur is a fake. Despite her uncanny similarities with the original, even Lyon acknowledges that she is a fake. I don't see why people think that Lyon would even think that this is an opportunity for him to see whether he can surpass Ur.

Gray's reaction here is the most logical, imo. Pure rage at having the memory of their master defiled.
