Mexican White boy

Uno's anger from hitting danny in the head definitely stems from something more than a simple accident. 
Danny came out of no where, and he was the new kid on the block ans he schools and amazes everyone with his hitting skills.  Uno is known to be the hardest hitter in stick ball and he realizes that danny hits way better than him.  After danny swung his last tennis ball and accidently ripped manuel one in the face, i think he felt that that was his Q to take out his anger but to cover it up and make it look like it was for his brother.  Obviously Nobody realized that it was because of this, because the reason seemed so clear, his brother got hit so he was ticked, but little does everyone know, he definitely despised danny and was jealous of his insane hitting talent.  I think Uno also resorted to violence towards danny because he didnt want to lose his reputation and get clowned on for having someone beat him at slamming tennis balls over roofs.
