Welcome to the party. INxx, 6w5/2w1/1w9, here. Being able to lock emotions up when focused or under stress is a huge deal - makes it easier to logically sort out a problem than panicking would allow for. I tend to make characters who bend the world to their will through via manipulation and confusion - full of intentional contradictions that all come together when their goals are achieved, all through careful remembrance of minor details and detailed dialogue.
