Cecil frowns, greatly perturbed, and checks again, squinting a bit either with the effort of checking vague metaphysical truth mandates or due to the wind off the sea. Nope, still unnaturally truthy, for reasons he can't ascertain and isn't inclined to really question.

Maybe the ocean's doing it." He gives the ocean a distrustful look.
