After a long night in the factory food started coming in thanks to the mayors efforts. Rosie woke up to the sound of mayo falling on the floor. She grabbed the food and bolted, but the mayor and factory owner spotted her. She knew her helpfulness wasn't going to work out.
Rosie was trying to run away but she got caught and sent to prison. The mayor was disappointed and scared for her. She though it might not have been the best choice.
The mayor spoke to her later and told her that she needed to let the town deal with the situation. She agreed and was disappointed in herself. This was the perfect opportunity for her to let the mayor take charge.
