As I've said before, this whole scenario was ridiculous. It required Nightwing, scion of the Bat-clan, leader of the Teen Titans, the Outsiders, one time leader of the JLA and generally all round best connected hero in the DCU to become Billy No-mates and no one notices.
Of ALL the heroes in the DCU for Blockbuster to target, Dick is probably the only one who could deal with a villain saying "I shall target your family, I shall target your friends, and I shall never stop" with a simple "My family starts with Batman, my friends start with Superman... get back to me on how that works out for you, would you?"
Then he opens the nearest door, and arrayed outside are half the Outsiders, all the Titans, and some JSA'ers along for laughs (Some have popcorn) "And I have the freaking JLA on speed dial, you idiot. These are just the ones who could make it here at short notice. Shift change at eight."
