Well, he's still there, which is a start. In a fit of Break-like pique, he's stretched himself out on the ground where he'd fallen, legs crossed at the ankle and hands clasped over his stomach. Yep. Here is a guy who is totally here on purpose. Nothing dubious going on in this here backyard.

...of course he thought of leaving. He knows perfectly well that he's been played. Everyone who knows him probably knows to play on his pride the way Lacie did if they want him to do something, but he can't exactly go against that, can he, not with something like pride. Pride is what you have when there's nothing else. So although he certainly considered it, he can't even leave out of spite. He doesn't turn his head when Lacie emerges, although he certainly knows that she is there, and the Headless Horseman can probably hear his teeth grinding all the way in the Marsh.
