in the crow city of angels, ashe recites what seems like an old poem when he's going after nemo and the club owner, he says one crow sorrow, two crows joy, three crows a letter, four crows a boy, five crows silver, six crows gold, seven crows a secret never to be told. almost seems like he's talking about what happened to him and danny. i've been trying to decipher what it means and what it comes from. any ideas?
