Constantine looking for Booster Gold ?

In justice league dark on the double page spread of Constantine's information on all the superheros on the justice league part it says he has to find booster gold and flash is more dangerous than anyone realizes, could constantine know about the reboot? it also says "who/what is PANDORA?" i have a feeling constantine will be playing a big role as he has notes on the Circle of Wizards, shazam and a whole bunch of other stuff!

ok umm Constantine is definitely playing a big part in Trinity War, just finished reading the issue
