Other mistake: Cyborg confronts Batman about throwing Yo-Yo off the roof and then turns on a hologram projector in his arm to show other super heroes.

She rakes her fingers across his shoulder and down his chest with her bloody fingers, leaving no trail of blood, but when she places that same bloody hand on her face it leaves blood all over her face and mouth. (00:35:05)
