Thomas takes Jack and Alfie to a warehouse site for work. The Pack are told to work carefully, or anyone who causes an accident will be sent back to the yards. Ned is worried since he always causes accidents, but he does not want to be sent back to the yards. His banksman tells him not to worry as he will watch over him. Everyone is working very carefully except Jack, who is not quite as careful as he is going too fast. Kelly tells Jack to slow down but Jack thinks he will be fine. However, he backs up and knocks over part of a stack of roofing slate, but no one, not even his banksman notices. Jack knows what he just did, but he does not want to go back to the yards, so he fills his bucket with gravel and drives away. Ned comes over and accidentally drives over the slate. His banksman blames him for knocking them over, but Ned corrects him that he did not do it. Unfortunately, no one believes him, so regardless of what he just said, his banksman calls Miss Jenny. As Ned is about to be sent away, Jack sees Ned heading to Thomas' well wagon as Alfie pulls up alongside. Alfie tells Jack about what Ned had "done" and that Thomas is taking him back to the yards. Alfie asks Jack what is wrong, but Jack has no time to answer him, so knowing that it was all his fault, Jack admits to Miss Jenny the truth that he knocked over the slates, which makes her briefly upset. Jack apologises to Ned for getting blamed and Thomas takes Jack back to the yard, proud of him for owning up.
