At Adrienne’s office, Kristen explains that Priya recommended Adrienne to her, but Emily doubts that she is telling the truth. That night, back at home, Emily re-reads the birthday card Kristen gave her and realizes that it contains a message in the coded language the pair made up as college friends. The message directs Emily to a shared Dropbox folder where she and Kristen store their travel photos. In the folder, Kristen has dropped a photo of Emily with Sebastian’s arm around her waist, walking down a Cambodian street.

Recognizing the photo as blackmail, Emily throws up in her bathroom and, immediately afterward, hears Kristen ringing her doorbell and calling for her to open up. When she lets Kristen in, she is so rattled by the photo that she can barely stay upright but tries to act normal. Kristen can see how ill she is and escorts her to bed. Before leaving the bedroom, however, Kristen notices what’s on Emily’s computer screen: the internet search on Jamie, a news story about the childhood house fire, and the emails to Lydia Brightside.
