Problem Solved
*The next day at school Austin and Ally talk to the principal about Tilly and she's told to see the counselor twice a week. She's reluctantly apologizes to Ally.
*After leaving office
Austin: I told it would work.
Ally: I guess you're right. I just hope she doesn't do anything when teachers aren't around.
*For the rest of the week Tilly doesn't bother Ally.
*Friday afternoon Tilly comes into Sonic Boom
Ally: What are you doing here? Get out.
Tilly: I came to make amends
Ally: I don't believe you. You're very manipulative and untrustworthy. I don't want to hear anything you have to say.
Tilly: Please I just want to be friends
Ally: No, I'm not being friends with someone who's held a grudge against me for 10 years. We were five in kindergarten. Get over it. It was just a song. Your anger led you to send me threatening texts and spread false rumors at school. Stay out of my life.
Tilly: Fine, I will. I promise I'll never bother you again. I'm moving anyway. You'll never see me again.
Ally: Good, now get out.
