Rewatch the latest episode and look at their faces. It's all crooked, and the parts are all disproportional. The mecha fights are 3D, so those aren't gonna get weird on you.

The problem with the sister sex scene is it made Theodor look dumber than necessary and changed nothing more than that. Taking it out would not change the flow of the story at all. Take note that I actually like incest stories, as is obvious from my sig.
