Subtitle Sunday Bloody Sunday
Date January 2006
Writer(s) Greg Rucka
Artist(s) Steve Lieber
storyline The unmarked car Montoya and Allen were in broke down. He pushed her a bit and she came clean about Corrigan. She'd done what she did to clear him, not worrying about taking the dirty cop down.
They got an emergency dispatch: Riddler and others were on the loose. A patrol car came by and they traded places with the beat cops.
When they got to the scene, they saw the Rock of Eternity exploding in the sky above Gotham City. In the rubble, they found Captain Marvel. He was muttering about the Spectre having killed the Wizard. The Spectre's visage shown across the sky. As Marvel told them what they were seeing, Montoya was shot by a green light. She pulled her gun on her partner, but Marvel got the "possession" to leave her. He explained the seven deadly sins were now free in Gotham. Captain Marvel, worried for his family, left.
Montoya and Allen came across the Fisherman - one of Aquaman's rogues. MacDonald and Driver shot him before he could do much damage. It was only then did everyone realize the world was coming to an end. They ran into some looters, but Montoya took one's kneecap out and the rest fled. Chris got Renee to the restaurant where her girlfriend worked. She gave him her car to get home to his own family.
