So, Constantine is back and searching for a lost man named Alec Holland, who went missing in the swamps. All of the sudden, Constantine gets attacked by Swamp-Thing, who just happens to be Holland. Now, Constantine has to find out how some normal guy was transformed into a living vegetable/muck monster. Also, Second of the Fallen has tracked down Constantine for some reason. I haven't done enough John Constantine research to come up with a good reason why. All I know is that the First of the Fallen was in the first Constantine, so the second should be in the second.
