"A lot of things..." Ren shifts a little in his chair. "They said some bad people were fighting for a...a Grail? And the bad people would have friends like them, and they were going to help me get it so the bad people wouldn't have it. They made it sound really scary, too...I thought wars were big things, but only a few people know about this one. But if you can get wishes, wouldn't a lot of people want to know about it? What if someone won it and wished for something terrible that hurt people?" He stares at Laoise solemnly. "But...I don't think they're right about everything. Adults know a lot because they're older, but...that's also why they can be wrong, isn't it? If you think you know how everything works, even if you're an adult, you'll be wrong even more than a little kid is."
Ren screws up his face in concentration and mimics the voice of the female Assassin. The result is alarmingly accurate - if Laoise hadn't been looking, it might have given her cause to think the Servant had materialized in the room. "'Only selfish people fight in these wars, Master. Even I am here because of selfish reasons.'" Dropping the adopted accent, he continues, "But they're not really bad. You aren't either, or you wouldn't have been so nice to me." He colors a little bit and busies himself with the mostly empty soup bowl.
