When separated from a Providence supply convoy while transporting toilet paper on a beaten down ice cream truck. Rex's truck with Noah and Bobo stopped on the mini market to buy some snacks. Rex came out of the mini market bringing soda cans in his hands and chips inside his jacket. When he gave the soda to Noah, he immediately knew that those sodas were expired. Bobo spat out his drink saying "it tasted like feet and not the clean kind". Rex ignored their protest and continued drinking it, liking it because they were free.
