They took him into custody and questioned him and he told them everything that Guren did such as receiving an invitation from the Thousand Nights but not coming to an decision and that this war started while he was considering his answer. He also tells Guren that his father is very weak as he broke down and talked five hours before he did but then his heart gave out in the end. He assures Guren that his father isn't dead as they revived him and sent him home.

He adds that he's sure that Guren will do be fine since to him, Guren is smarter that him. Guren jokingly answers that if he was that smart, he wouldn't be caring about gaining more power.
