David Gale has a similar appearance to AI Gale except he has blonde hair and blue eyes, opposed to AI Gale's green hair and eyes. David Gale, however, lacks AI Gale's characteristic hood and is typically dressed in a white lab coat. Furthermore, Gale's constant habit of touching his forehead before speaking can be attributed to the fact that David wore glasses. Gale is unintentionally acting as though he's still wearing glasses and trying to "adjust" them.
