As for any chance of letting him be. Well that just wasn't about to happen, she liked this whole singing thing, and thats what she was gonna do. She was gonna wait it out, sing until he caved and did. He was letting slip some real interesting things through the songs.
"Would you make a sacrifice if you knew if it were right. Well the answers' there, if you look inside. Will you run and hide. Or will you fight the fight.

She was pushing it, more than a little, but he wouldn't walk away from her completely, there was no way.
