Okay, here's what I understand.

People seem to think the spike Ruby used to tease Zwei with a turkey should be visible somewhere. Whether it is behind her of in front, I'm unsure. Because they can't see it, they think that therefore either Crescent Rose is broken, or there has been an animation error.

But the angle she is laying on the side of the airship combined with the angle the shaft of Crescent Rose is on means that the spike is not visible. Instead, the spike is hidden by Ruby.

The head of Crescent Rose, including the part you circled in the picture Jaden, is not visible in the image of Ruby hanging from the side of the airship because we are too clos to Ruby. She is hanging from the lower half of the shaft; the head of Crescent Rose is behind the 'camera', and out of the field of view.
