First episode to show a pre-abby.
In the imaginary conversation between CJ (Djimon Hounsou) and his wife (Simone Missick), he expresses desperate feelings of emotional fatigue and isolation. She replies with 'miles to go.' This is part of a line from Robert Frost's poem, 'Stopping by Woods on a Snowy Evening.' The verses are 'The woods are lovely, dark and deep,//But I have promises to keep,//And miles to go before I sleep,//And miles to go before I sleep.'
