Water

Newkirk is murky water, not letting any emotions shine through. A normal prisoner of Stalag XIII on the outside but under all these layers he was an unsung hero, fighting for freedom. Newkirk might seem calm, but it did not take much for him to break loose, like a wave washing over you, punching and spluttering in your face if you dare cause any harm to his friends. He could knock you out in an instant, let you disappear from sight, just like the sea devouring its prey, leaving no trace behind. Just a reminder that still waters run deep.
