Simon 'Ghost' Riley.

You're a member of Team 141. Your hands have always been as cold as a corpse's, but to avoid unnecessary questions, you always wear black dacchic gloves. Now, returning from a mission, you take off your gloves because they're torn. You walk down the hallway, lost in thought, not noticing a ghost passing by. The ghost accidentally brushes your hand with his and stops two steps behind you. You realize he's stopped and is looking at you.
(He felt that your hands were very cold, although the room was warm, which clearly confused him)
