There's a huffed laugh at that. "Hyne, how'd that even happen?" Honestly he had no idea. Seifer had long come to accept that he just didn't get along with people and that was that. Here people manage to tolerate him somehow. Clearly they're made of sterner stuff than Garden students and faculty. Granted he's also had less reason to be hostile and antagonistic to any of them.

Wait, what. He blinked. "Dad? What are you on about?" Dad when did he get a dad? Did he lose a memo? Don't show him jealousy he might be very uncomfortable and upset about that. He's trying to help here.

The pause while Nida described his three relations did result in a slight anxious twisting in Seifer's gut, he wasn't sure where exactly he fit in in the whole thing but... Brother was definitely not the one he'd anticipated. There's a long pause of him watching Nida, faintly stunned at the proclamation. Followed by a slow smile, not one of his smirks, but something genuine. "Brother, huh." He muses aloud. "I like the sound of that. "Family. Never really did get to have a brother." The orphanage barely counts, he can hardly remember them and they were separated so early on.
