Robin #0 DC Comics The Beginning of Tomorrow

While Robin and Nightwing stake out some safe-crackers, they discuss what led each of them to become Batman's crimefighting partner. Nightwing also reveals a particularly unpleasant episode from his time as Robin: Two-Face had set up a double gallows trap, to hang either Batman or Gotham's new district attorney. Dick tried to double-blood Two-Face but failed, leading to the death of the D.A.. Both he and Two-Face still remember this incident clearly, though Batman has never mentioned it to the current Robin. Returning to the Batcave, they meet Batman, who says he needs a rest, but this time will hand the mantle on to someone it always should have gone to: Nightwing.
