Betrayal! A white hot realization. Damn his stubbornness. He wanted to get through to Zilliah so badly. Solena hadn't liked this idea at all. If she knew he had gone off with the fae, she'd have downright forbidden it, but it had all been in the moment. He thought he had finally found a way to force middle ground, to breach the gap between himself and the unknowable so that the shadows would stop moving around him. DOING things was what mattered. It's what mattered with Niall, and maybe Zilliah would work the same way.
The fae wasn't human though. He didn't think the same way Elliot did, and Elliot would never, ever be able to wrap his head around that. So this felt like betrayal instead of fun. Granted, so much of that was that the Brown boy took what he did so very seriously. This was his life now. Skulking. Stealing. Sneaking. And before long, hitting people from behind. He had made some futile grasps for something else, subconscious and pathetic, really, and maybe this was one of the last of them, but it was well past the point of mattering. There was no going back to being a squire now. He had a taste of it, and it had a hold on him.
Now he was careening forward, however, and lessons took over. He could gracefully dodge out of the way at the cost of his balance or his control, or he could storm forward, driving his foot down upon the poor unsuspecting sleeper, really planting it for a moment so he could keep control. That's what mattered. Control of your body. Control of the situation. Oh, his new victim would be awake now, but the room was dark and he would be hurting, disoriented. So Elliot would dart into the shadows, cloak whisking around him. He would regroup and do whatever next on HIS terms.
