Batman: Arkham Shadow, not unlike every Arkham game before it, has its core plot or theme bundled intimately with its subtitle. The idea of someones shadow in relation to their ego or id is assessed heavily while interacting with Drs. Jonathan Crane and Harleen Quinzel, and this theme runs parallel with the story and its depiction of characters until credits roll, sometimes subtly and other times brazenly. Many characters have sides of themselves they conceal, for example, and how someone presents themselves isnt always a particularly truthful shade of who they actually are, leading to conflicting personas.
