From NBC:
She has discovered a makeshift Internet that exists within the walls of the federal prison in Philadelphia: If she scoops enough water from her toilet bowl, LaRose can communicate with other inmates by speaking through the sewer pipes -- they call it "talking on the bowls."
By talking on the bowls, LaRose fell for a new man. She knows little about him other than what he has told her. But she finds him wise, compassionate and righteous. He is not a Muslim but promises to convert when he gets out. That way, they can marry and be happy.
