London is the 20-year-old bank teller at the bank the robber attempts to rob. She’s deeply unhappy, lives most of her life online, and acts as though she’s about 14 years old, so she’s rude and dismissive to the robber and everyone else she encounters. However, when Ro invites her for coffee after the police let the witnesses go, the novel implies that London and Ro will become friends. London is also deeply moved when the robber writes her an apology letter in the weeks after the attempted robbery, though she refuses to admit how much it affects her until she’s much older.
