[Scorched] Mist-Powered!
While Jack doesn't have any inherent powers, he has not been left untouched by the mists. Being a rather empathetic young man, this is the avenue the mists have worked in to develop abilities he would have never dreamed of. His sensitivity to strong emotions from other characters has been sharpened, so that even though they might hide it from their face, he'd know how they were really feeling. If he makes contact with them, he can establish something of a psychometric link that would allow him to see what had happened to make them feel so strongly as they were. This is not limited to people, but can also work in regards to places and objects too, so long as there was some strong tie to a person or persons, i.e. a place where someone died, an object that a person held dear because it belonged to someone important to them. It's more palpable the more recent something has happened, but majorly determined upon the strength of the emotions displayed, and unfortunately negative emotions are much easier to pick up than positive. Prolonged exposure can possibly result in such emotions bleeding into whatever Jack's current emotional state might be.
