"Let's go, she has her own things to deal with, don't bother her." Mrs. Hawkins pulled Carolline's hand, she just wanted to see the child alone. For the past few months, she hadn't been able to figure out why, given her understanding of Carolline, even if she had fallen out of love with her older son, she wouldn't have thrown herself at another man so quickly, let alone have a child with him.
Moreover, her older son hadn't been back at all in the past few months, with each month spent in different places, making himself a money-making machine.
About the woman named Phoebe Miller whom her older son said he liked before he left, she had also specifically learned that the two did have a relationship before Matilda Ferguson. But these days, her older son seemed to have truly fallen for Carolline, not at all pretending. There must have been something going on between the two.
