Faye also writes about having delivered Emily's second baby, and how she thanks God for helping her with the dangerous delivery. Tara is furious that her mother delivered the baby at home while knowing how dangerous it was going to be. She closes the email and leaves the house.

After completing her fellowship, Tara travels to the Middle East with Drew. She is in awe of the experiences she has had since leaving home, but also mourns for her relationship with her family. She decides to sever ties with her family for one year in order to heal.
