Reese had noticed her zealous drinking. When the waitress had gone and the band had started back up again to eliminate the chances of anyone overhearing, "Is that how people drink off-the-grid?" He smirked to show he was joking, although... it was only a half-joke, really. She seemed eager to get a lot of liquor in her quickly.
"You've played paying gigs?" he asked next, interested. He had never inquired how involved she was in her music career; for all he knew it was just a hobby. "Have you got any coming up? I'd like to hear you."
In response to the karaoke comment, he snorted and sipped at his drink. "No, no... the world almost faced extinction not long ago. It doesn't need to suffer the agony of hearing me try to sing."
