How does paragraph 45 contribute to readers’ understanding of Antonio’s perspective?

Amigo Brothers:

Antonio was passing some heavy time on his rooftop. How would the fight tomorrow affect his relationship with Felix? After all, fighting was like any other profession. Friendship had nothing to do with it. A gnawing doubt crept in. He cut negative thinking real quick by doing some speedy fancy dance steps, bobbing and weaving like mercury. The night air was blurred with perpetual motions of left hooks and right crosses. Felix, his amigo brother, was not going to be Felix at all in the ring. Just an opponent with another face. Antonio went to sleep, hearing the opening bell for the first round. Like his friend in the South Bronx, he prayed for victory via a quick clean knockout in the first round.
