Okay so because I'm insane I was thinking about the line that Batman says to tube-Joker in #7 "the devil's in his hole". This refers, I think, to the Led Zepplin song Achillies Last Stand, which was created when Robert Plant was in a wheelchair from a car crash. The lyrics to this song go like this:
It was an April morning when they told us we should go And as I turned to you, you smiled at me, how could we say no? With all the fun to have to live the dreams we always had Oh, the songs to sing when we at last return again Sending off a glancing kiss to those who claim they know Below the streets that steam and hiss, the devil's in his hole Oh, to sail away to sandy lands and other days Oh, to touch the dream, hides inside and never seen, yeah Into the sun, the south, the north, at last the birds have flown Shackles of commitments fell in pieces on the ground Oh, to ride the wind, to tread the air above the din Oh, to laugh aloud, dancing as we fought the crowd, yeah To seek the man whose pointing hand, the giant step unfolds To guide us from the curving path that turns our feet to stone If one bell should ring in celebration for a king So fast the heart should beat as proud the head with heavy feet, yeah Days went by when you and I bathed in eternal summer's glow As far away and distant, our mutual child did grow Oh, the sweet refrain soothes the soul and calms the pain Oh, Albion remains sleeping now to rise again Wandering and wandering what place to rest the search The mighty arms of Atlas hold the heavens from the earth For the mighty arms of Atlas hold the heavens from the earth From the earth I know the way, know the way, know the way, know the way Things to note: the dream references in this song and the Joker's references about how he can't tell dreams from reality. The line seems to also refer to Devil's Hole, in Jersey, UK (not New Jersey). There's not too much lore surrounding how it got its name other than a ship wrecked masthead was modified to look like a devil and placed there.
