Who is the other shadowed figure?

Also in that issue, John vaguely refers to events in the SWAMP THING series, telling Nergal that "The elementals are all going loopy, y'know."
That issue explains the prophecy that will involve Swampy: "There has been a prophecy incontrovertible - engraved on a stone dredged up from Hell. At the winter solstice, a conjunction between nature and super-nature -- a birth. The child will be a healing power in this realm."
Another page shows a flashback to SWAMP THING #49 and #50.
