One by One

Erin excuses herself to her room to think, trying to rationalize why Liz would have stolen the key. She is gone for too long and Liz comes to find her, scaring her. They both pretend to sleep until Erin goes upstairs to use the bathroom, leading Liz to realize the staff key is gone. Upstairs, Erin lets herself into Elliot’s room and finds his phone plugged into his external charger. She uses the thumbprint scanner and his corpse to unlock the phone, which opens to the Snoop app and lets her view the two people whom Elliot follows—Topher and “Anon101,” which the reader recognizes as Liz’s Snoop profile. Erin eventually realizes this as well and sends a text to Danny.

Downstairs, Liz worries about Erin and thinks of her own history of social rejection. She finally goes after Erin in time to watch her come out of Miranda’s room, claiming mild food poisoning. Liz checks on her room where, folded inside a hidden liner in her suitcase, is a bright red ski jacket, which Liz purchased to obscure her identity in the event of an altercation with Eva. She suspects that someone has moved her suitcases.
