Wh-- twelve?? This man is obviously joking, but twelve? Brain looks nothing like the same age as Ven, thank you very much. He laughs at that, not actually offended. "I'm a bit older than that. Try adding five years."

It's not exactly much to tack on, but Brain feels like it's a difference. He always was one of the older kids in his parties, and was definitely older than the majority of the leaders. Whatever. The guy was just teasing Brain. No harm done.
