Karis stares at the Doctor for a long moment, incredulous. What is wrong with this man? She finally breaks out her self-imposed stupor to wave a gauntleted hand at him, voice rising for the first time since they've landed. "Are you serious? Are you really...? It's just a Light-forsaken rock! It's nothing special! You can find rocks like these anywhere! Are you really worried about me hurting a rock? Did I damage its precious feelings?"

She trails off, glowering. No, she does not care about their prospective host. She does not care about the mission.
