[If Ren was insistent it was because he was so anxious to know someone else who knew his father so well. For as long as he could remember it was only their immediate family he could talk to. Hunters and Vampires alike did not approve of his existence so it wasn't as if he could ask anyone second hand about his family. Ichiru was his family, whether the hunter liked it or not.]
Ah- are you sure? I think it would... it would make father very happy if you came to dinner. I think he was planning to make tomato soup...?
[He knows hearing him address his father as such would surely only rankle his uncle further. He wasn't comfortable with his relationship with his family any more than hunters and aristocrats were when Ren was growing up. He understood the tension it caused.]
