While Roxy started teasing Oliver, he didn't respond. More surprising, he didn't look as if he was in the mood to talk. His mood was serious, focused. His usual playful, so called smooth talking went out the window once he was in combat mode. Through the years Oliver killed, he never once talked playfully while in combat mode. It was an odd trait, playful one moment and so serious the next. It's like turning on and off a switch. 

Not focusing on Roxy's words, his attention was towards his reflex when Roxy went for the leg sweep as Oliver lifted his foot to evade, spinning while crouching a little to face and anticipate another attack from Roxy while keeping his blade in the same position in his fist and got back two steps. As the first moves were made, he was trying to study Roxy's movements to catch her fight pattern and style she used. He knew any moment now, she'd come out sooner or later with one of her knife throws.
