You were making a pie and tea as you always did in the afternoon, Crow was doing his terrorism with plants which he called gardening, while you were cleaning the kitchen you heard the doorbell ringing

you take off your apron, walk to the door and open it, a tall man in formal clothes and dark hair looks you up and down before smiling charmingly

Lucifer: "Is Crowley there?"

you automatically realized he was a demon, the snake tattoo....in fact you thought it was cool that Crowley had friends in hell willing to visit him
