You go insane and decide to eat the note. Why in the name of all that is holy would you do this? Hell if I know, but you did it anyways. It tastes absolutely awful and you'll probably have ink poisoning soon. Why did you do that?

As you wolf down the note like your life depends on it, someone drops a scroll through the barred window in the door.

Oh, what's this? An unforseen side effect of eating the note was the time until your execution appearing at the bottom right corner of your viewport. Very interesting, I guess there was some use to eating that note for whatever absolutely stupid reason you did.
