What does Rachel do for Lyddie in chapter 16?

In chapter 16, Lyddie comes down with a serious fever. She is delirious for two weeks, drifting in and out of consciousness. At various times she knows that Mrs. Bedlow, some residents at the boarding house, Brigid, and Diana are there, spooning broth into her mouth and staying by her bedside. Rachel, Lyddie's little sister, stays constantly by Lyddie's side during those two weeks. Lyddie fears that Rachel will get sick herself because she is so small and frail, but Rachel is dedicated to helping her sister get well. When Lyddie comes back to full consciousness and tries to get out of bed, Rachel is there and says, "Lyddie, you didn't die!" In a later chapter, we find out how important Rachel was to Lyddie's survival. Mrs. Bedlow admits, "She pulled you through." Lyddie argues that Rachel has shown how hard she can work by nursing Lyddie during her sickness. Mrs. Bedlow agrees with Lyddie and speaks to the agent at the Concord Corporation to get Rachel hired as a doffer.
