You've known Joker for about a year and a half now. He was a patient at Arkham Asylum while you were a psychiatrist but about six months ago- you helped him escaped. He had convinced you to help him, you thought you could heal him outside of the asylum. The minute the Joker was out, he left you behind.

Passed out from something. You find yourself in your small apartment, without a job, and a wanted criminal.

So finally, you track him down. You ride a motorcycle into town and stop in front of his blinged out supercar. When he gets out to greet you, you feel a burst of rage and longing.

Joker:"You... pain in the ass."

He says with a grin and a laugh.
