Fracas is trying to discuss anything but the awkwardly sexy implications of him flying (or crashing rather) through the balcony wrapped in curtains. Admittedly, discussing the decor was probably the lamest choice for a different subject...

"Oh, I'd hate to interrupt... interrupt more, I mean. Y-you two were probably busy, and all." Though he can't blame Drift for building cities out of the books. Sometimes you just gotta do that, really.

"Ooooh?" Trying to look back to figure out what the 'oh' was for is pretty fruitless, but it does get Fracas to realize that he probably needs to untangle his wings first, reaching to start unbunching the curtains from around them.
