He was actually quite impressed, her certainty that he was still there not just driven by fear. She could some how sense him and he was quite curious to know how she had managed that. Not curious enough to try to communicate with her of course, the projected illusion of his invisibility would have been broken and likely would have only caused them to 'freak out' further. He could only think life was a strange wonderful mess, that he had managed to set off events with such minimal effort and yet got such a great feast in return. He would have to continue to be gentle, he decided, if this was to be the outcome.
At least the boy didn't seem too harmed by their encounter, not that he was anything other than indifferent to the lives of those around him, but he had caused heart-attacks before and knowing what to do with the bodies was always a little troubling. For a moment he had worried that he had sparked off something terrible, with the teen causing the park to wither around them and with the woman building that golem, something that would have gotten back to the Sidhe or their enforcers and would have led back to him. But all seemed well now, or at least it would be if the young man got away from the woman and she kept control over that thing she created.
Deciding that he perhaps ought to help end things he took a few steps closer to her, moving in a wide enough circle so as not to set off whatever it was that allowed her to sense him through the illusion. Eventually he was behind her, moving steadily but slow, ready to slip off his illusion and project a peaceful image into her mind as he had done to the boy. But it didn't happen, not in that moment. He had stopped mere inches from her, the smell of her hair or perfume kicking the broken mind he was inhabiting into a series of memories so strong that he had to completely stop to sort through them.
