Who: Lucifer and Mary What: De jure infidelity When: Tonight Warnings: Hot sex.
Lucifer had walked from the Vatican towards Rome and found an airport. Then he had flashed his passport and bypassed various security measures, because Romans have the unflinching assumption that anyone from Vatican City is incapable of crime. He purchased a coach ticket to New York City and declined the headphones; he didn't need to listen to Mean Girls.
On the way he answered a prayer in a vaguely disinterested way, almost completely forgetting about it by the time he landed in New York. From the airport, he took a taxi to Mary's apartment building and walked in. He rode the elevator to her floor and knocked on the door.
When it opened and he saw Mary, he said, "Either Justice has left me or left the universe. Either way, I'd like to talk."
