that old guy is differently a Kuchiki look at his scarf it the one Byakuya were's.
What i like to know is who is that guy next to Shinji can't see the picture good ? I think it's that guy who annoy's Love by spoiling his manga.
In that exact same picture, Rukia's captain is the one closest to the front. The one in the back that he's talking about is indeed the long-haired blond Vaizard. He was on the title page of this chapter along with all the other Vaizards.
