Ed watches Oswald carefully, aware of the trembling and hoping it's reflex, not fear (Oswald doesn't really know fear, Oswald knows fury and rage and charges at fear with an iron poker or a cheese knife, teeth bared to rip out its throat if he has to) that makes him tremble. He leans back a little to check his expression, that this is wanted still. "Okay?" His voice is soft and husky.
