This is every bit as unnerving as wandering about Asshai, so Melisandre feels right at home, presumably while Rafe wonders if it's too late to just leave her to her fate.

She'll offer a friendly (but overtly religious) greeting directed at whichever area seems to hold the most unseen horror, take a careful step or two in that general direction, and set down one of the two loads of food Team Fuck has brought along for this purpose.

It's an offering, she'll say. So you eat that and not us, Rafe will think.
