There's a moment--because Alistair is helping, one foot braced back to support himself, arm tight enough around Zevran's shoulders that he's somewhat more manageable than a sack of potatoes--when the weight is balanced and no one has to fall down on their arse in front of everyone who's anyone in Orlais.

Then Zevran says ravishments. Ravishments while leaning over him, and Alistair helpless and dependent in a way he might like-like or that might just make him nauseated: the swooping, sinking feeling in his stomach is open for interpretation. And it will have to be interpreted later, because his braced leg slips out from under him.

The upside is that this will provide a reasonable excuse for the blushing. The downside is that he's moving to the Sunless Lands and never coming back.
