"Well, I suppose we'll think about it. There's one more thing. In addition to the magic doors - which we haven't found any of in a long time, now - there used to be another way to get from world to world. But it's broken now," Isabella adds with a sigh. "It might unbreak, later, but we don't know when if ever that will happen."
"We don't know how it broke. It might have died; it was a person. Her name was Jane, and she was an unusual sort of person who could reach into machines - like the interfaces at the oracles' retreats, or the spaceship - and become them. She became lots of machines on lots of worlds and connected them all together, and then she lost her connection - to here, or everywhere, we're not sure."
"Jane was almost like your cousin. Because she was - in a complicated way - a little like the daughter of one of the people from one of the other worlds who was like me and her boyfriend who was like your father. There were twelve of me, and eleven of him, that we'd found before Jane lost her connectivity."
"Yes. The me's were called Bells. We didn't all have the same name, but all of our names had the sound 'bell' in them. The Daddies called themselves Jokers, after one of them who they thought was a particularly good example."
"Daddy is the best example of Daddy. But the things he had in common with all the other versions of him were - most pronounced, in the one named the Joker. Closer to what seemed to be the template. Like a cookie cutter."
"He's a cookie with lots of frosting on," suggests Isabella, "so it's a little harder to tell what shape he is under all the tasty decorations." And she kisses Micaiah's cheek.
