For all of his mental preparedness, Julian found that actually going to the world of the living was still something of a shock to his system. He had known only the Rukongai, after all, and so to see this world, with all of its many wonders and technologies...it made the man sick to his stomach. That his people lived in veritable poverty, while the world moved on past them to this era of modern magic... It was good that he was a master of maintaining his facade so well, else he would have scowled.
But, instead, he simply sat upon the beach with a smile on his face, keeping a wonderful facsimile of enjoyment across his features. Was he having fun? No, of course not. He never had fun. But this sort of social interaction was exactly the sort of thing that brought him further into the Gotei, made him more trustworthy, all of that. It was exactly the sort of thing that he rather desperately needed in his journey, like it or not. So, here he was. Watching the waves of Earth, making friends with his "comrades."
How he missed the Rukongai.
