When the music started, Spencer smiled and started dancing, did what he did best. There were other people in the theater too, he just didn't see them. He did the intro to the song, then when he heard that specific point in the song, he began to sing.
"She was more like beauty queen from a movie scene. I said don't mind, but what do you mean I am the one?"
He sounded incredible. No one in that theater have ever heard a powerful voice like that from a boy. Everyone was mesmerized by the sound of Spencer's voice and his awesome dance steps.
"She told me her name was Billie Jean, and she caused a scene, then every head turned-"
Spencer stopped immediately when he looked to his left. He took one look. One. His face went pale, and he dropped his microphone. He stood stunned for a full minute, then bolted to his right backstage. He immediately went to the dressing room he previously occupied, grabbed his stuff, and ran out.
Everone was stunned. Why did he stop? He sounded so good.
It was William.
Seeing that Enrique was only a mere boy, he managed to shake him off and lock him in a closet. He then ran to grab his son before he could do something that William thought was "stupid", "weak", or "embarrassing".
When he was backstage, he heard music playing. He thought, "Damn him! When I get him..." he walked toward the stage, hell bent on teaching his son a lesson, but more to see his son fail.
He expected the worst when he saw Spencer was starting. He watched intently, waiting for Spencer to miss a step, skip a note, anything. He didn't count on him making any mistakes. What's more...he sounded amazing. William never realized how good his son sounded, until he realized...he never even heard him sing before.
"Oh, god...what have I done?" William thought as he watched his son sing his heart out. "How could have I spent so many years criticizing him when I didn't even know what I was criticizing? God, I should've paid more attention...".
When Spencer ran out, he was scared out of his mind. What happened to his best friend? He had to go back for him. He just had to.
He had to.
