"You are." He couldn't help but agree. It was nice, seeing his friend just having fun and being normal, not that feral killing machine he'd met years before. Nebula was slowly becoming more... if not human, then something akin to one. Less of a machine, at least. He could give her that much credit, even if he didn't know exactly how to categorize what she was now.
It took no time at all for her to score again and she made her little quip there, but even as he reset the board, he was smirking back at her. "Come now, Nebula. You know me better than that. Me? Concede? Never again."
He was back on the attack without even breaking eye contact with her. That was just to show off, but then he did need to focus, so he lowered his gaze.
