[That's a good way of putting it, both literally and figuratively: Simon does breathe, but not to keep his dead heart beating, and when he's not using his lungs to speak they tend to be unconsciously, unnervingly inanimate.

Similarly, there are ways he's just like anyone else and ways he absolutely isn't. Like his body, his expression tends to be unnaturally still. The further he gets into this discussion, the more signs he shows -- tiny ones, a twitching of the mouth here or a squint there -- but he knows he's difficult to read when he wants to be. It's a talent he's cultivated. Right now, he could be almost talking to a wall, except for the very fine edge of irritation in his voice.]

Well, that's up to you. As for me, I think the setup in my cabin will be suiting my purposes just fine from here on out.
