Oz might have given his brother a real answer, except that at that moment the woman (creature) had looked in his direction and he had momentarily lost the ability to form coherent words. His mouth went dry and his tongue was too sluggish. This interaction already felt sour to him, no matter how beautiful she was (and no matter that she was ostensibly innocent in this; it was hardly an act of aggression for her to merely look in their direction, however it felt). He didn't enjoy feeling as though he had been robbed of his charm or wit, the two pillars around which he'd built his public persona for most of his adult life. So he was keen to pull his brother off to the side and find something else to do with their time and attention, but of course Endymion had other plans.
He was going to make a damned fool of himself, sure enough, and it became immediately apparent to Oz that the fact of their being in a crowded ballroom was hardly going to prevent him. "Endymion Keats Dempsey," he hissed under his breath, but the idiot was already smiling across the room at her like a fool and probably hadn't heard him — and certainly wasn't going to be so easily dissuaded from foolishness, if he had. It would only be harder to pry him away if he actually made it across the room and started talking to her (and who knew what she might do or say that would make everything worse), so to prevent that, Ozymandias stuck his foot out into his brother's path, hoping to trip him. Maybe the floor could knock some sense into him, although admittedly the chances of that weren't high — but in any case, a fall might succeed in making him look graceless enough to be dismissed by the young veela.
