In her diary, Hayley doesn’t write out names but refers to people by their first initials. Ella, for example, is “E.” Hayley writes about how in love she is and the night she fell for “S.” He makes Hayley feel valued and like she is not to blame for the “shittiness” in her life, and they exchange phone numbers. A few nights later, Phoebe upsets her, and Hayley goes to a bar. By the time she realizes that she is too drunk to drive, she’s ashamed to tell her friends, so she texts “S.” He picks her up and takes her home. The attraction between them is palpable, but he will not kiss her because she’s drunk. The next day, he tells her to come over after school. This time, they kiss. She says that the “fire” between them starts small and grows into a “conflagration.”

Ella is lifeguarding at the YMCA with Seema. Sean is there, working on the building’s electrical system, and Seema can tell that he makes Ella uncomfortable. However, Seema has a big test tomorrow, so once the pool closes, Ella sends her home to study. Ella reflects on Hayley’s diary entry, realizing that she never knew how intense Hayley and Sawyer’s relationship was.
