hey little sister, what have you done?

In the week following the Joker's escape, things are quiet. No sightings or exploits make the news. As far as anyone can tell, he vanished out of his cell overnight and then left town.

He didn't leave town, of course.

At exactly the time they would have had their next session, down to the minute, he breaks into Harleen Quinzel's apartment—politely locking the door again behind him—and settles onto the couch in her living room to wait until she gets home.

It takes a while. Pretty soon, he curls up and goes to sleep.
