- During the first seven days of 52 ground work is laid with the focal characters. Ralph Dibny hits rock bottom with the destruction of his home. Renée Montoya takes solace in the bottom of a bottle. Steel involves himself endlessly in rescue operations. The Question begins looking for answers. Black Adam secures his position in his homeland. Booster Gold returns to the public eye and the sponsors' bottom lines. Along the way is a memorial for the fallen, a mysterious message for Ralph, a hero losing her toys, and the abduction of Doctor Sivana.
There are two continuity hiccups of note at the memorial: 1) the inclusion of the members of Shadowpact seems at odds with the events from Shadowpact (2006) #1; and 2) it is unclear who is in attendance as Nightwing. It may be Dick, who had left with Batman and Robin for a "year away" at the end of Infinite Crisis (2006) #7, or Jason Todd, who was revealed to have co-opted the identity sometime during that year in Nightwing (1996) #118.
