After surveillance shows Caleb and Lina left five minutes ago, Mr. Luke orders his team to find them. At a midday outdoor spot Lina and a man are openly affectionate, drawing scorn from passersby. Lina flirts but then worries aloud about Caleb’s faithfulness and notices a phone case identical to the one she bought him, pauses, and tells herself he can't be here. She drops her phone, which draws closer scrutiny; a bystander reacts and someone calls, "Sara?" — a sudden recognition that threatens to upend the search.
