A little before this arc began, I wrote(ignorant of Morrison entirely at the time, and I was really weirded out to discover this had been going at the same time--this has happened to me more than once with that bastard Morrison; ask me sometime about the KID ETERNITY proposal I wrote right before reading about his one coming out) a play called "Suspension of Disbelief," which is pretty much all on this tack, and that's what I did to my protagonist: he finds out he's a character in a play, but thing is, this makes no difference, because his finding out is also in the script. As is his reaction. He starts destroying the set in a rage. That's in the script too. He even tries to kill the actor playing him(He holds a gun to his actor's head) but the gun doesn't work because I decided it wouldn't at that moment. So I devised a far worse method of torture than Morrison, I think, with no way out.

Morrison's actually nice to AM in the end, finding possibly the only way "it was all a dream" could ever work.
