Keith didn't have to ask if she was talking to him, there wasn't really anyone else watching her after all. He ate the last bite of his burger and took a quick drink to clear his mouth before saying anything.
"I was going to watch. I've never played and I was learning from watching your strategy." She didn't sound like she cared if he joined in but she might look at it like he did practice with fighting or his weapons, it was boring to deal with a beginner.
