In the movie Constantine, during the climax in the mental hospital, Gabriel is shown wearing many hospital bracelets.
What, if anything, do these bracelets signify?
Neither the official novelisation nor the original script mention Gabriel's costume.
The question has been asked over on the Movies & TV Stack: "Gabriel's Wristbands in Constantine". Alas, most answers it has received are speculation without source‡. However, they do establish that the bracelets read "Awakening", "Sorrow", "Rage", "Passion", "Love", "Joy", and "Melancholy".
‡ I've since added a copy of the answer I've accepted here, over there.
