Watching Angelina, Cade had no intention of doing any convincing. Not in any way she probably expected, that is. The she was looking at him, the flick of tongue over her lips, told him all he needed to know.
That headbutt had disoriented her as much as it had him, and Cade took advantage of it. He feinted, throwing his body right then immediately shifting left instead, waiting for Angelina to either enter his space to block - which would give him opportunity to get behind her - or dodge away - and leave her open for him to place a firm but painless blow to the back of her knee and make her crumple.
