Jewel and Darl went to see Cash to see if they can help him finished up building the casket. The casket is made for Darl’s mother who is lying in the bed and going to die very soon. Darl’s mother chose Cash to make her casket because she chose him to build it and everyone grant her wish. Darl also thought of making profit in breeding more chicken so they can help him get more eggs to give to Miss Lawington and have enough to make cake to make extra cash. From the few pages Darl waits by his mother’s death bed and told her to “don’t worry” and “have some rest”, showing his last thing he can do for his mom.
This summary seems inaccurate. Where did you get this information? If might be helpful for you to include the lines that you’re paraphrasing so we can refer to those passages as well and see if we agree about what they mean. Jewel and Darl, for example, do not offer Cash help, and Addie never overtly chooses Cash to build the coffin.
