Tiberius was usually conscious of trying not to rise to Antigone's jibes, but if this was her way of baiting him, he wasn't sure what she was getting at. He had been quite content with his animagus form, all things considered. He still wasn't sure it was worth all of the effort that had gone in to obtaining it, but he had never been too keen on the idea in the first place. As far as animals went, it was fairly useful. He'd already used his new wings to search her out more effectively than he could have with a simple spell. It was a respectable form to have; it was a bird of prey, a predator. Was he overlooking something? Some reason she might have to disdain him for it?

"Why?" he asked, glancing over at her. It wasn't the wolf he told her he'd be expecting, when they'd first had that conversation years ago — but he hadn't ever really anticipated that, since he'd lied about it being his patronus form. A falcon was more useful than a wolf, anyway, for most tasks. A wolf probably would have been better suited to snapping her little cat neck in its jaws than a falcon, but — well, hopefully that wouldn't be relevant again after their earlier spat in the woods.
