John Constantine Cameos
A cameo is a quick, on-panel appearance by Constantine in which he is inactive. Memories, dreams, and crowd scenes are common cameo appearances; Constantine may even have a line of meaningless dialog. For the most part, cameo appearances are not important to the story, although they sometimes foreshadow an actual appearance by Constantine. If the character is not referred to by any other name, I'll assume that the appearance is the 'real' John Constantine, and the appearance goes here. A surprising number of these occur in bars...
