So wow, this was a very packed issue with lots of teases. So much to digest. I literally don't even know where to begin. Was Plastic Man actually stuck in a container in the batcave this whole time? Duke's mom has some sort of immortal powers or something? Hawkman is back and is the one who had the weird version of the cover. The Anti Monitor tower that destroy's universes is back, makes sense, since the threat will be a dark multiverse. And of course, we have the new 52 Joker back. Should be interesting seeing Duke's reaction since this Joker is the one who poisoned Duke's parents. It doesn't surprise me Joker was the one talking to the two of them since the new 52 has been a master at fooling even Bruce as seen in endgame.
Can't wait for the casting next month!
