Who is Julius Clarke from The Emperor's Children and what is their importance?

Julius is a gay man approaching his thirties. He is the son of a fierce but gentle Marine from Danville, Michigan. In moving to New York City and attaching himself to Danielle and especially Marina, he has shed all that he ever was born to, striving to surround himself with the rich and powerful. He wants a long term relationship with someone, but that dream clashes violently with his addiction to chance sexual strangers. Julius comes away from his best chance of being part of a great gay couple scarred for life.

Julius has high aspirations to be rich and powerful, but would rather be with someone who has these qualities than cultivate them for himself. He reaches for the dignity and solidness of a relationship, but is unable to forsake the wild life.
