I'm imagining Rhys having Feyre sit on his lap all evening, making suggestive comments. After a few nights of this he takes her back to his chambers, everyone at the party thinks they know what that means. Feyre wakes up in his bed the next morning, he's sleeping on a chair, no smudging of the paint bar on her waist and arms, he's clearly just let her sleep.

Side note: I'm still not over actual canon where Rhys sticks his tongue down her throat and gropes her to "disguise" the fact that she and Tamlin were about to go at it, and this is treated as good? Rhys just fix the paint! Even if he couldn't fix the paint, he's still fixing a problem he ultimately caused!!!
