Capt. Renault: “What in heaven’s name brought you to Casablanca?”
Rick: “My health. I came to Casablanca for the waters.”
Capt. Renault: “The waters? What waters? We're in the desert”
Rick: “I was misinformed.” 

 Be Warned: This rabbit hole is about water.
                   And God. It's about water and God.
                   If contemplations of faith disturb you, proceed no further.
                   I don't want you to feel “ambushed.”
