A new preview of Batman #13 has been posted by USA Today. Scott Snyder talks about the upcoming series saying,
The Joker is coming and saying, 'Remember all these awesome times we had together,' which are obviously not awesome at all for Batman, but in the Joker's mind are these incredibly loving and terrific encounters over the years,"
In his own oddball way, the Joker sees Batman as the ruler of Gotham and himself as the court jester — Snyder is including Peter Pan and fairy-tale imagery as the Joker shows his messed-up adoration.
"He believes he often brings the worst news of Batman's own heart to him in the form of these terrible nightmares he has to fight. "If that's his purpose, then he sees this family in a lot of ways as interlopers and people who make his idol, his Bat-king, weak."
Snyder went on to say: "Let's make this Joker story the biggest, baddest, most terrifying thing we could possibly do so that no one wants to use the character again in this way for another 20 years."
