- 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; and 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.
