The Scarlet Godwins - Four

A packed episode in which Marley elaborates on a number of
remarkable assertions, including the claim that drugs no longer
have any psychoactive effects on her. She discusses a game of
no-blinking, fondly recalls a burglary, and mentions her sister
slightly more freely. Meanwhile, deep in thought, Otto pieces
together Charlotte Godwin's university years. In doing so, he is
led further into the nature of his relationship with a person who
is vital to him; the person he is talking to in his head.
