(I own the cover) What if Nico wandered out of the hotel by himself before he and Bianca were supposed to be taken out? What if he accidentally shadow traveled to Gotham City? What if he met the Joker there and was adopted by him? (Warnings: cursing, violence, gore, torture, death, and experimentation on human) Don't worry, Nico will be a happy boy in this! But he will be facing many hardships and pain.
