James is pretty upset that his choice to go find that strange book got Kitty in so much trouble. Hovering between them, is Intention-his and Kitty's thoughts and then thoughts around him imparted by others. We have dove too deep into intention in the comic yet, but I'll finally confess that's what is up with the words. James is only see pieces of it right now.
The mist of Intention seems to signal when his powers are about to act up, as he has another uncontrollable magic spell, healing Kitty and Christian both this time (though Kitty is more noticeably healed). He has apparently used too much magic, as he immediately faints, still glowing. The three look very concerned about what has happened.
