Gotham: I Am the King

Xia Mu suddenly finds himself in Gotham City, and his timeline seems to have become a little scrambled.

One moment, he's waiting for treatment in Arkham; the next, he appears inside Wayne Manor.

Am I a patient?

Xia Mu wonders from time to time. But do mentally ill people realize they're ill?

“Damn it! Someone's after me!”

“Can't talk now. I've got to run for my life!”

“Joker! Stop laughing for a second! How about I tell you a riddle!”

Tick... tick...

[Almost every DC character could appear, as long as I haven't forgotten about them. Feel free to remind me, too.]

[PS: The pacing won't be too fast ⊙∀⊙!]
