Celie is holding a letter in her hands. It’s from her sister, Nettie.
She finds out that Nettie’s been writing to her for years and years, but she thinks Albert’s been throwing away the letters.
In bed, Shug asks Celie about Nettie. She wants to know all about Nettie and tells Celie that she saw a letter from Nettie once when Albert picked up the mail.
When Celie wants to know why Shug wants to know about Nettie, Shug replies that Nettie was the only thing Celie ever loved – besides Shug herself.
