One lovely afternoon Miles gets a rather urgent call from Ivan.
"Yeah, she pick up thing or person and put it. Places she see. Mommy bracelet have a gem but not me."
"Yeah." She sighs, then says philosophically, "But, Jane break because putting her one Mommy or maybe gems or both I dunno in the bad Jane breaking world. This one not magic, but door not going home dunno how it pick where going!"
"What do you know about how the door works? Maybe we can figure it out."
"Well, for Shell Bell is special. But usually, it eat a regular door. Like, door to room, something - poof, now goes Milliways. Go in, go out back where coming from! Jane do time too and she have part in back yard of bar, but, without Jane do time, time only go if door open. So stay longest while come out still whenever. Shell Bell stayed weeks sometimes when she little to find stuff for bring home. Now she have enchantress aura and can make door eat any door she want, and when going out again can go other place. Home or Downside or anyplace. Jarvises can make door in them whenever wanting to also, if practice."
"Hmm. When it eats a door, does it look and work just the same as the door it ate? If it ate, oh, the door to my house," he waves thereat, "it'd open and close just the same way?"
"Yeah. Some people can make a door be even if not Shell Bell but not Shell Bell people can't every time doing it for sure. Doors like Elspeth but not always. And the door is alike itself."
"Are there a lot of people who know Jane and can go between worlds whenever they like, or is it mostly just your parents and their - others of themselves?"
"Is it possible for someone to open the door and let someone else through into their own world who came from a different one?"
Or not by accident, if someone wanted to strand this little girl on a hostile planet, perhaps for reasons having to do with her powerful parents.
Which will make it hard to track them down, in the not-by-accident case.
"Yeah. Mommies probably find them if someplace where a Jane, but if someplace else maybe not!"
"Yeah. Hmm. And there's no good way to get a door to - Milliways, is that what the place is called? - on purpose from the outside, it sounds like."
"No. Can try open lots of doors but no Jarvis no Shell Bell can't sure about finding."
"Hmm... did you bring any magic with you when you came here?"
"Not much," she sighs. [There's this] "and being safe and that all things. Not old enough for have wishes. Blarg."
"I... see. How does it work? Can you talk to just anyone with it?"
"If knowing who talk to, mm-hm. I can put people, can't put putting people though."
"So - you 'put' me, just now, but that only lets me talk to you, since we're the only two people around with this particular magic?"
