"Indeed, if successful, JoJo will prove that the label have held her against her will..."

"The label" is singular. "Have" would be used for a plural noun. Therefore, the correct structure of the sentence should be:

"Indeed, if successful, JoJo will prove that the label has held her against her will..."

Please, please consider studying grammar/English. It's constant errors such as these that make ThatGrapeJuice seem so unprofessional and keep it on the D-list.
